Data Acquisition

Quality Assurance Using High-Precision Vacuum Pumps

Delphin TopMessage Modular Measurement Data Acquisition System

CHESTERLAND OH—October 31, 2011

CAS DataLoggers recently provided the data acquisition systems solution for a company providing vacuum solutions for a wide range of modern production and analysis processes as well as in research. The company’s high-quality products found use in everyday devices such as TVs, light bulbs, and air-conditioning units, and also high technology processes including CD/DVD manufacture and medical instruments. Their core competence was the development of systems for vacuum generation and processing gas extraction, placing high levels of quality and precision not only on their own products but also on the technical equipment used for vacuum production and development. At the testing department, the lab team had set up a large test bench where the company inspected its vacuum systems as early as the development stage. Complex testing procedures delivered important data to project engineers including electrical values, vacuum performance, volume flow rates, etc. which enabled them to determine the limit values of their products. These trials then established the parameters that would be used at the final inspection. Development was never at a standstill at the company, with the latest trends moving towards dry compressing fore pumps. In response, management began planning to increase production of these pumps, realizing that this required the best quality assurance procedures, which in turn required cutting-edge data acquisition systems capable of extremely sophisticated measurements and featuring powerful yet user-friendly data acquisition and evaluation software.

The company installed a Delphin TopMessage Data Acquisition and Control System in its final vacuum pump inspection department where all systems were precision-tested following their assembly. The TopMessage device was used to acquire and record data provided by the pumps.

The TopMessage device processed any signal quickly and reliably from just a few thermocouples right up to thousands of measurement points. Universal inputs enabled any unit of measurement to be acquired (e.g. temperature, pressure flow, vibration etc.) often entirely removing the need for costly measurement transducers. Data then underwent direct scaling and linearization. Offering universal inputs and outputs with extended functions and software channels, the TopMessage handled 30 analog inputs or 48 digital inputs and could connect up to 10 slave devices for extended functionality, making it ideal for both small and large applications requiring the processing of thousands of channels. This modular and scalable system featured high accuracy with up to 24-bit resolution and 2 slots for analog or digital input or output cards as well as a CANbus for expansion modules. Housed within an industrial grade enclosure, the TopMessage also featured signal conditioning within the device, an Ethernet interface, and screw terminal connections.

Master and slave devices each accommodated two I/O modules. The customer was presented with a range of I/O modules to select the best one for their application, with different modules available for any number of channels and sensor types. A network interface enabled the TopMessage device to be integrated into a TCP/IP network or to be directly connected to a PC workstation or laptop/netbook computer. Online measurement data could be transmitted, saved and processed, and the data could be stored simultaneously within the TopMessage device itself on its local memory.

To observe what was running when, the company’s vacuum pumps were equipped with a guard which provided constant monitoring of the entire system, giving users early warning of any possible pump malfunctioning. The guard had a serial interface which was connected to the TopMessage device at the test bench, which in turn recorded and reported all important data. The output was then archived for internal use. These reports allowed the company to document their equipment’s condition at the date of supply, which was useful for future customer queries.

Additionally, the TopMessage system was upgraded to include ProfiSignal Basic universal software for data acquisition, test automation and data acquisition applications. This software’s wide areas of application ranged from simple data storage and visualization to a complete automation solution offering reporting. ProfiSignal Basic was easy to configure by PC, and plant engineers found the representation of the channels to be clear and intuitive with a Windows Explorer-style operation. The software was also used to set control parameters enabling automated test procedures to be performed. Management quickly switched from the older MHouse software to ProfiSignal because it offered so many major benefits: this one software package covered all project requirements. The laboratory head explained the situation at the test bench: “Here we can use ProfiSignal to select a start-time for test profiling to begin. This has been set at night so that by the morning we will have a pump ready to be inspected at operational temperature.”

All the functions provided by ProfiSignal were utilized in this application, while the TopMessage hardware performed the important control tasks, as the device functioned without the need for any PC support. Operation, visualization and parameter settings were all performed with ProfiSignal running on a PC. Setup was easy: the software enabled developers to generate systems for tasks which previously could only be met by setting up complex control systems. ProfiSignal was neatly structured according to projects, applications and analysis diagrams, and a structure diagram could be generated with just a few mouse clicks for the vacuum pump test procedures. ProfiSignal had simplified the lab’s test procedures, with each task within a test procedure represented by blocks which acted as containers for program code. Clicking the container allowed access to the code, enabling intuitive programming. The parameter diagrams proved to be just as helpful, enabling a simple method of entering pump test parameters and generating parameter diagrams. Time-consuming tasks such as correcting program bugs or syntax errors became a thing of the past thanks to ProfiSignal’s intuitive operation and simple configuration.

The company was entirely satisfied with their new measurement data acquisition system and eventually came to use more than 20 of Delphin’s TopMessage units. The TopMessage made for an easy install, and another major benefit was the TopMessage’s modular design which enabled future expansion of the testing program with additional inputs and outputs. All in all, lab engineers found that the TopMessage system was very reliable and highly accurate, and operators were easily able to work with the ProfiSignal Basic software for automation and reporting. Users were offered a tool which helped to warn of imminent malfunctions and to detect long-term changes taking place, thereby enabling maintenance procedures based on the actual condition of the machine.

The company’s laboratory head explained, “ProfiSignal can be easily set up and running without any need for specific training, in contrast to the majority of other complex products available on the market. But Delphin’s software and hardware is still capable of meeting both our simple and complex measuring requirements. Using the Delphin device has enabled us to considerably shorten lead times from initial planning through to the start-up of our testing procedures.”

Delphin TopMessage Data Acquisition System

CHESTERLAND OH—October 4th, 2011

CAS DataLoggers recently provided the data acquisition solution for one of the world’s leading manufacturers of large diesel engines, turbochargers and complete drive systems. The company specialized in manufacturing diesel engines for shipping, power generation, and heavy road and rail vehicles with power ranges from 116 to 9000kW. Turbocharger performance determined overall engine performance, fuel consumption, and emissions, and were regularly tested using test benches where they were subjected to high levels of thermal and mechanical stress as well as exposure to temperatures of up to 750ºC (1382ºF) and a 5.0 pressure ratio. These test benches were designed to test the most critical areas and to optimize the robustness, efficiency and operation of the components, and could rotate the turbochargers as rapidly as 90,000 rpm. Given the complexity of these tests, plant managers began to see the need for a sophisticated data acquisition system offering highly accurate measurements, fast signal processing and easy configurability. The customer was also considering integrating more advanced test scenarios utilizing additional inputs in the near future, and therefore a modular system was required to enable management to upgrade the system easily with more input and output channels whenever needed.

The customer installed a Delphin TopMessage data acquisition system in a control cabinet in the turbocharger testing area. For this particular test bench application, about 80 analog signals and about 20 digital I/O channels were required. The analog inputs recorded pressures, volume flows, valve position, and temperatures, while the counter inputs measured rotation speed. The customer’s specific TopMessage system contained the following modules: 1 TopMessage Master with 1 GB memory and ProfiBus DP Slave interface; 3 TopMessage Slave extension units; 6 ADVT modules with 90 analog inputs for temperature and pressure measurement; and 1 DIOT module for digital I/Os for pulse and speed measurement. The system’s software consisted of ProfiSignal Basic process visualization and monitoring software with 250 inputs.

During testing, a high level of accuracy (+/- 0,2 K) was especially necessary when recording the temperature measurements. The ProfiBus-DP Slave interface of the TopMessage was important to integrate it with the PLC system which controlled the overall test cycle. Suited to many different data acquisition, data logging, and testing applications, the TopMessage device processed any signal quickly and reliably from just a few thermocouples right up to thousands of measurement points spread over several plant areas. Offering universal inputs and outputs with extended functions and software channels, the TopMessage handled 30 analog inputs or 48 digital inputs and could connect up to 10 slave devices for extended functionality. This modular and scalable system featured high accuracy with up to 24-bit resolution and 2 slots for analog or digital input or output cards as well as a CANbus for expansion modules. Housed within an industrial grade enclosure, the TopMessage also featured signal conditioning, an Ethernet interface and screw terminal connections.

The TopMessage system was a modular device for data acquisition and automation with a master/slave design making it ideal for both small and large applications requiring the processing of thousands of channels. Master and slave devices each accommodated two I/O modules. The customer was presented with a range of I/O modules to select the best one for their application, with different modules available for any number of channels and sensor types. A network interface enabled the TopMessage device to be integrated into a TCP network or to be directly connected to a PC workstation or laptop/netbook computer. Online measurement data could be transmitted, saved and processed, and the data could be stored simultaneously within the TopMessage device itself on its local memory.

Additionally, the TopMessage system was upgraded to include ProfiSignal Basic universal software for data acquisition, test automation and data acquisition applications. This software’s wide areas of application ranged from simple data storage and visualization to a complete automation solution with reporting. ProfiSignal Basic was easy to configure by PC, and plant engineers found the representation of the channels to be a clear and intuitive with an operation similar to Windows Explorer.

The customer realized several advantages after installing the Delphin TopMessage data acquisition system in the turbocharger test area. The TopMessage itself made for an easy install, so much so that the first test run was performed after just 2 days of installation. Likewise, the installation and configuration of all the temperature sensors was also hassle-free since no additional converter and signal conditioning unit was required, and configuration of individual mimics and HMI screens was simple too. Another major benefit was the TopMessage’s modular design which enabled future expansion of the testing program with additional inputs and outputs. All in all, plant engineers found that the TopMessage data acquisition system was very reliable and highly accurate, and operators were easily able to work with the ProfiSignal Basic software for automation and reporting.

How to Select a Portable Data Acquisition System

Choosing the Ideal Solution for Any Application

CHESTERLAND OH—September 13, 2011

Portable data acquisition systems are used worldwide to capture data and conduct routine testing of vital infrastructures such as mass transit systems, power grids, and bridges, as well as heavy industrial processes and applications. These powerful yet compact data acquisition devices play an important role in the testing and monitoring of many critical systems, and selecting the most suitable device for a given application requires careful consideration. The ideal portable data acquisition system for most users is a compact, lightweight unit powered by either a self-contained battery or a single DC power source, requiring no other connection to function other than the sensors being monitored. Operating in remote areas, a user interface and means of communication with the device become vital features. Signal conditioning such as gain and filtering as well as high-capacity non-volatile data storage are other important considerations.

When selecting a suitable portable data acquisition system for their specific applications, users face a bewildering choice of available manufacturers, models and specifications. Each system has its own configurations that make some units more suitable than others for certain applications. Additionally, purchasers must first consider several demanding requirements not necessary for traditional laboratory devices. Any existing and potentially damaging environmental extremes including temperature, excessive humidity, liquids, dust, shock and vibration should be carefully considered. Other relevant questions to ask include whether the data acquisition equipment can support the particular mix of sensors that will be used, as well as determining if the device has adequate memory and storage to support the specific project.

Before deciding on a specific manufacturer or solution, users need to form a clear idea of the results they require of any system they’ll be using. Sampling rates, as just one factor, are available in a wide variety from as low as once per day to higher than a million per second. Anticipating the future project’s needs today will save precious time and money on installation. Data acquisition system designs range from the simple to the complex, with an attendant variety in performance, features, and cost. Fortunately, in the face of all these options, fundamental guidelines are available for portable data acquisition equipment users to consider before making their purchase.

Of course, the main function of data acquisition systems are their basic function to accurately record data, and here the wide spectrum of degrees of accuracy attainable by units available on the market can make this a more involved decision than expected. A reliable constant, though, is that the accuracy of field measurements is heavily based upon the sensors being used. For most sensors that have been calibrated in the laboratory and installed in the field, accuracies in the range of 0.01 % to 1 % of full scale are typical, with many other sensors having less accuracy. The particular system’s input types must also match project requirements–for example, an application requiring extensive analog measurements would benefit from the portable Delphin Expert Key 200 series of data acquisition system, which features a full 28 analog inputs.

Likewise, the sampling speed of DAQ systems must also be taken into account when determining accuracy. The device must acquire signals quickly enough to avoid any loss of the data. The necessary data acquisition speed is calculated by using Nyquist’s Sampling Theorem, which states that a signal must be sampled at twice the frequency of the spectral signal components which are of interest in order to accurately reconstruct the waveform. The Delphin Expert Key 200 series mentioned above has a 100kHz maximum sample rate.

Also vital to many users’ considerations are the environmental conditions which the device will be subject to. Portable data acquisition equipment is naturally susceptible to damaging environments, such that ruggedized packaging of the DAQ unit itself, as well as its electrical components, is an essential manufactured precaution to ensure both device and data integrity. For example, portable DAQ equipment used in heavy industrial applications often needs to withstand a broad temperature range. In the absence of ruggedized models, a portable enclosure may give adequate protection for the system. In these harsh environments, and to retain their portability, DAQ systems need to be as compact and lightweight as possible. Further, beyond withstanding these environmental extremes, portable data acquisition units need to be able to survive in high shock and vibration environments such as the trunk of a car or onboard an airplane, or just as a result of the occasional accident such as being dropped by its owner. Other sealing and packaging precautions such as watertight housing should be under review for aquatic applications such as flow rate measurement and wastewater monitoring which partially or completely immerse the device.

For remote applications where access to a standard 120V AC power outlet isn’t available, electric power to the system can be provided either through an internal battery pack, or the user can connect an external wire to a DC power supply. Additionally, in order to conserve power and avoid unnecessary processor loadup, users with minimal processing requirements can select a lower performance CPU and rely on a capable storage system.

When analyzing recorded data and exporting to other formats, many users rate software primarily by how user-friendly it is, which often depends on graphical interface style, menu navigation and help tips. Continuing with the earlier example, the Delphin Expert Key 200 series features ProfiSignal software for data storage, display and analysis.

Choosing a portable data acquisition system featuring internal signal conditioning capabilities can greatly improve system quality and performance. Different types of signal conditioning include amplification, attenuation, and filtering. As always, the specific application involved and the types of sensors used to make the measurements will decide the type of signal conditioning required—to measure temperature, a device will probably need to use thermocouples or thermistors. Thermocouples produce a voltage that varies with the temperature, but connecting a thermocouple to a data acquisition system creates a cold junction point at the terminals that acts as a thermocouple itself. Signal conditioning is required to compensate for this, or else the recorded temperature which is taken from the total voltage will be altered by the additional voltage of the cold junction point. Signal conditioning can also be used for signal amplification to mitigate any noise distortion, and is also useful when a DAQ device is connected to other transducers such as strain gauges, accelerometers, etc.

When designed to monitor remote unattended systems, suitable DAQ devices have communications capabilities utilizing telephone connections or wireless systems to download data to remote PCs. They also require ample built-in storage and user interfaces to enable setup and control. Advanced solutions use built-in testing capabilities allowing users to sit back as the system acquires the data.

Taking into account all these specifications when choosing the right portable DAQ device is certainly an involved process, but one made easier by always keeping the needs of the present and any future applications foremost in mind.

Underhood Thermal Management and Engine Cooling Analysis

Delphin Data 64 KTM Temperature Measurement System

CHESTERLAND OH—September 13, 2011

Malaysian automobile manufacturer Proton needed to test the underhood thermal management and engine cooling performance in their new manual 5-speed Proton Persona 1.6 M/T Line test car. The thermal test program was designed to check underhood part performance in order to ensure that the parts were working within design requirements after being exposed to high temperatures during driving and climbing. Engine cooling analysis testing was performed to verify cooling performance under various types of driving patterns including high-speed runs, while idling, and hot soak and dead soak. To collect enough temperature data to get a complete picture of the Persona’s thermal distribution and engine cooldown, Proton’s automotive engineers needed high-performance, flexible data acquisition devices for use in their test setups, supporting large numbers of channels able to connect to the very broad range of thermocouple types the program would rely upon.

The Proton plant installed four Delphin Data 64 KTM Temperature Measurement Systems in its test chamber and in the trunk of the test car, with three of the units acting as slaves to increase the number of channels available to the master. These compactly-constructed measurement systems were protected within industrial-grade 19-inch rack enclosures, with 250 of their 256 available channels used for the thermal management tests. During engine cooling analysis testing, the KTM devices were used to measure the temperature of the engine cooling system, (radiator and water temperature in a water jacket), the pressure of the test car’s A/C system, and engine revolution (RPM), requiring about 85 channels.

A portable, all-inclusive device for multi-channel temperature measurement, the Delphin 64-KTM data acquisition system featured 64 channels of universal thermocouple inputs of every type including types E,J,K,L,N,S,R,T,U–providing plant engineers with a great deal of flexibility for high-precision, 24-bit resolution temperature measurements and achieved, depending on thermocouple and measurement area, an absolute accuracy of < 0.2 K. The modular design enabled the other 64-KTM units to be slaved to a master by simply connecting the additional devices, potentially processing over 5,000 measurement channels this way. The 64-KTM devices performed stand-alone data logging and recorded the test data with a partitionable 1 GB internal memory storing up to 128 million data records. The memory's independent data recording capability provided data security for long-term measurement runs. Integrated engine speed pulse measurement (rpm) was featured, as well as integrated high and low pressure measurement based on strain measurement. The sophisticated 64-KTM systems offered many features to ensure high-accuracy measurements, including differential inputs with 110V isolation and galvanic separation to prevent measurement errors from earth loops. Inbuilt network filters for 50Hz or 60Hz networks suppressed any power supply interference, and cold junction compensation served to isolate measurements from environmental interference and ambient temperature fluctuations. Scaling was provided as required. An Ethernet interface allowed easy integration into the plant’s network. Convenient data evaluation was then made available at any PC workstation in the plant. The 64-KTM also had interfaces for Modbus and Profibus and a TCP interface to a network was also available for online measuring. Proton engineers set up many of the channels for limit values, calculations and event processing. These channels enabled the computation of characteristic values during measurement runs, and also included the calculation of moving averages and enabled monitoring and alarm functions. The master system was able to transmit e-mails or portray limit value violations within an alarm table. Live data analysis and post-treatment was provided with the user-friendly ProfiSignal Basic evaluation software, included free with the device. Plant engineers appreciated its intuitive configuration and also utilized ProfiSignal for measurement data archiving and online/offline measurement data analysis. A driver was also available for all current measurement technology software or OCX driver. The Proton plant’s test programs benefited in several ways from installing the four Delphin data 64 KTM temperature measurement systems, the most immediate of which was the large number of channels available for the auto plant’s demanding test applications. The devices’ universal thermo connectors were easy to use and enabled quick and simple attachment of the many different types of thermocouples used in testing, with each measurement made at a high resolution and accuracy.

Diesel Particulate Filter Testing on Vehicles with GPS Logging

Delphin TopMessage Data Acquisition and Control System

CHESTERLAND OH—August 15, 2011

CAS DataLoggers recently provided the data acquisition solution for Twin-Tec, a German developer and manufacturer of environmentally friendly products and technologies for reducing exhaust emissions, including a wide range of diesel particulate filters and catalytic converters for automotive applications. TwinTec was heavily involved in producing products for retrofitting and upgrading already approved vehicles as well as corresponding replacement products. In Germany, the government encouraged all owners through financial incentives to retrofit their filters since many old vehicles had no diesel particulate filtration. Many German automobile owners became interested in adding a particulate filter to their exhaust system in order to protect the environment and benefit from the reduced vehicle emission taxes. Twin-Tec was therefore developing many different retrofit filters for many different brands. Each filter required testing on the road under typical driving conditions to determine filter efficiency—however, virtually every new filter also required a new design due to the wide variety of exhaust systems and their varying temperature and pressure operating levels. During test drives, the filter temperature, pressure, engine speed, idle times, vehicle position and speed all needed to be measured accurately and reliably to ensure that the filter met all required standards. In order to record all the test data, Twin-Tec needed a sophisticated data acquisition device capable of extreme accuracy and fast signal processing and that could capture the wide range of data required in the tests.

Twin-Tec installed a Delphin TopMessage Data Acquisition and Control System with ADVT and DIOT modules in combination with a GPS sensor to record measurement data from the filters in tandem with vehicle position information. The whole system was installed in a small weatherproof enclosure and its sensors were interfaced to the enclosure through special connectors. During the test drive, all test data was recorded on the TopMessage’s internal memory. Engine RPM was recorded through a separate speed meter (DAB 500 from AVL) which was providing TTL pulse output. The pulses were then recorded by the counter and inputs of the DIOT module. The live data was visualized through a mimic interface using ProfiSignal Basic software.

The TopMessage featured 2 slots for analog, digital input, or output cards, as well as an Ethernet interface and CANbus for expansion modules. The analog inputs could be attached to RTD sensors, thermocouples, volt or 20 mA signals, enabling any physical value to be acquired. The measurement data was saved as scaled and linearized to the device, and scaling was pre-configured for all current thermocouple and RTD sensor types. The high measurement accuracy, up to a 24-bit resolution, enabled high-precision measurements without need for any signal amplification. Additionally, the device processed any signal quickly and reliably from just a few thermocouples right up to thousands of measurement points spread over several plant areas. The data acquisition device also featured screw terminal connections and up to 1 GB of local memory. The TopMessage also offered powerful alarm and programming capabilities to allow the device to process measurements and initiate actions on its own. The TopMessage could be used for local data acquisition and logging when connected to a PC; for remote unattended data collection connected to the internet; or as a stand-alone device.

In order to record the vehicle speed and direction, a special NEMA driver for a GPS sensor was developed. This driver was interfaced to the TopMessage through serial RS232 port. A separate COM channel was created for the GPS information like speed, direction, altitude, etc, and all the data was stored directly on the 1 GB TopMessage data logger memory. After the test drive was finished, all the data was analysed with the ProfiSignal software included free with the TopMessage. This user-friendly software provided for the acquisition of measurement, control and test data as well as functions for archiving, analysis, operation and monitoring. It was also possible to convert the GPS data into a KLM file which could be loaded by Google Earth to plot various measurement channels like vehicle speed, filter temperature or pressure of position or engine speed.

Twin-Tec benefitted immediately from installing the Delphin TopMessage data acquisition system in its diesel particulate filter testing program. Filter temperature, pressure, engine speed, idle times, vehicle position and speed were all measured in the test drives using one powerful device. Twin-Tec subsequently used 5 TopMessage systems to more smoothly run the testing. The universal analog inputs made it easy to connect all the temperature and pressure sensors, and engineers found it easy to configure the TopMessage’s ProfiSignal software to show live reading during the test drives. The data acquisition system’s 1 GB internal memory provided storage capacity for several thousand test drive kilometres, and the interface of the GPS sensor also gave Twin-Tec valuable additional information about vehicle speed in combination with engine RPM and particle emission. Additionally, the small and compact size of the TopMessage (200x73x118 mm) made it an ideal fit for installation in the small enclosure. Additionally, internal calculation and logic channels were used to trigger data logging when test conditions were reached.

In the event that Twin-Tec needed to expand the number of channels used, Delphin slave module expansion chassis were also available to expand the TopMessage to a maximum of 1000 hardware/software channels. Up to ten slave devices, each with identical housings and each equipped with two I/O modules, could be attached to a master, with any combination of I/O modules being possible. Check out the TopMessage’s product page here.

Data Logging With Remote UMTS Access In Natural Gas Dehydration Plants

Delphin Data Acquisition Systems Provide Remote Monitoring Solution

CHESTERLAND OH—August 8, 2011

CAS DataLoggers recently provided the data acquisition solution for a state-owned oil and gas company located in Eastern Europe involved in developing natural gas in distant gas fields. The gas came out of a wellhead for processing in either of two dehydration plants. These plants extract water from the gas before sending it through a compressor station and then pumping it through the pipeline system. However, since the two dehydration plants were based in a remote location, the company needed a standalone data acquisition and logging system to record production and process data from the plant and also to gain remote access to all recorded data. This system would have to be able to perform high-precision measurements and also feature sophisticated alarm and programming capabilities enabling the device to process measurements and initiate actions on its own.

Plant management decided to install a Delphin TopMessage Data Acquisition System in each of the two dehydration plants. Additionally, one ADVT module with 15 analog inputs and one IOIT module with 24 digital inputs for status monitoring were also installed in each plant. The TopMessages were then interfaced via Ethernet LAN to a MoRoS UMTS router to provide remote access functions. In case of an accident in hazardous areas, each complete system was then fitted inside an explosion-proof box outfitted with EX barriers. Within its protective enclosure, each Delphin TopMessage was then interfaced to 3 tank level transmitters using a 4-20mA analog output signal, and also to 3 gas volume conversion devices from VEGA through an RS-422 Modbus RTU interface (see Figure 1).
Figure 1: Functional Application Architecture

The TopMessage data acquisition device was capable of both Ethernet networking as well as direct PC connection (P2P). Its analog inputs could be attached to RTD sensors, thermocouples, volt or 20 mA signals, enabling any physical value to be acquired as needed. The measurement data was saved as scaled and linearized to the device, and scaling was pre-configured for all current thermocouple and RTD sensor types. The maximum 24-bit resolution measurement accuracy enabled high-precision measurements without the need for any signal amplification. Each TopMessage device could be equipped with up to 30 analog inputs or 48 digital inputs, with any possible combination of I/O modules.

Ideal for many different data logging, data acquisition and testing applications, Delphin TopMessage systems perform tasks in the fields of process technology, test engineering, and research and development, offering quick and reliable signal processing from a few thermocouples up to thousands of measurement points spread out over the plant. 1 GB of local memory stored all readings. Housed in its sturdy explosion-proof enclosure, the TopMessage system featured 2 slots for analog or digital input or output cards, as well as an Ethernet interface and CANbus for expansion modules. Screw terminal connections provide secure connections and reliable operation. Additionally, the TopMessage’s small size of 200 x 118 x 90mm made for a quick installation.

The dehydration plant operator based in the save area had a local monitoring PC running Delphin’s free ProfiSignal Klicks software. ProfiSignal Klicks offered a user-friendly development system for programming the data recording and reporting functions with no specialized IT knowledge required. The software also contained functions for automating processes and generating user-defined reports. Operators used the software’s mimic panel to monitor plant performance and also set up input screens for test parameters, test sequences and reports through the Klicks automation programming language. This provided engineers with a flexible software tool for generating their own complete applications. Utilizing the UMTS router, the control room operator at the head office had remote access at all times to the data from the TopMessage device and could see live data and downloaded data from the system memory. Additionally, the data download could be automated by using the scheduler function of the DataService Configurator. The dehydration plant itself was covered by an EDGE G2 mobile communication network.

The oil and gas company gained several benefits from installing the Delphin TopMessage data acquisition system in each of its two dehydration plants. The TopMessage data acquisition device, equipped with the UMTS router, served as an effective solution for this application covering all requirements. Additionally, the TopMessage’s compact size made the system easy to install in the explosion-proof box to guarantee its safety. Additionally, remote access was easily configured with the UMTS router, which also provided networking functions for local PCs and printers. The TopMessage system itself supported many serial interface standards so that VEGA Scan EK220 volume conversion units could be interfaced. The popular ProfiSignal Klicks software was included free to develop an operator user interface, including mimics, and also added reporting functions.

As an option for larger projects, up to 10 Delphin TopMessage Slave Modules could be used as expansion chassis to increase the master unit’s capability up to 1000 hardware/software channels, with all data transfer between master and slave taking place via a CANbus. The slave modules are connected via CANbus to the master with a maximum bus length of 100 meters. Check out the Delphin TopMessage’s product page here.
