CAS Debuts New Portable High-Speed Data Acquisition System

Delphin Expert Key 200

CHESTERLAND OH—October 3rd, 2011

CAS DataLoggers has teamed up with Delphin Technology to introduce the new Delphin Expert Key 200 Portable Data Acquisition System, the latest high-speed, plug-and-play solution for data acquisition of measurement and process data, experiments and product testing, and automation of machinery and test stands. This compact device’s wide areas of application range from fault troubleshooting, reliability testing, process and laboratory automation, and research and development. Two Expert Key 200 models are available: the Expert Key L pop-up tabletop device for industrial applications, and the Expert Key C model for laboratory uses and installations in control cabinets. Together these high-accuracy units are an ideal solution for projects requiring a compact yet powerful device.

The new Delphin Expert Key 200 Data Acquisition System has been specifically designed for laboratory and experimental applications including automation of measurement processes, process visualization, and experiment, trial and test stand automation. This latest generation of data acquisition system comprises a complete hardware and software package in a lightweight, portable unit with benchtop enclosure, suitable for both tabletop and wall-mounted usage (200L model) and in a panel mount enclosure (200C model).

A true plug and play device, the Delphin Expert Key200 lets users start collecting data as soon as the device is connected to a PC via USB or Ethernet, making configuration and setup quick and simple. The Expert Key 200 offers 28 universal analog inputs which can be connected to mV, volt, 20 mA signals, thermocouples, and RTD sensors, enabling any physical value to be acquired including temperature, pressure, and flow-rate. A universal digital input is available for acquiring status, frequencies or impulses, and a counter input is also included. All inputs and analog/digital outputs are universal and galvanically-isolated to protect against earth loops. Sensors and actuators are connected via plugs located on the side. The Expert Key 200 also features plug-in screw terminals for secure connections and a maximum sample rate of 100 kHz. Measurement data is saved as scaled and linearized to the device (e.g. PSI, ft/sec, GPM). Scaling is pre-configured for all current thermocouple and RTD sensor types, even for large applications, and signal conditioning is also included. Experiments can be controlled or events triggered via analog, digital or by a PWM output.

Free ProfiSignal Go professional PC software is included for the online and offline monitoring and analysis of measurement data. This user-friendly software enables set-up and online or offline monitoring as well as measurement and data analysis. ProfiSignal Go also interfaces with other third-party applications including LabView and Diadem, and data can be exchanged with other systems using an OPC server or Modbus TCP. An OCX interface is also provided to interface with custom programs. The Expert Key gains added value through a comprehensive complete package including ProfiSignal Go and a multitude of software interfaces and drivers for the problem-free integration of external systems, saving the expense of having to acquire additional software.

The Expert Key 200L is designed for table-top and wall-mounted usage, with mounting brackets included in the delivery along with a power supply adapter. A pop-up detachable lid enables a clear overview of connections. Sensors and actuators are connected via plugs located on the sides. The L model has universal capability and is particularly suited to laboratory, servicing and testing environments. The Expert Key 200C model has the same design as the L model apart from the metal housing design, which enables the devices to be installed in cabinets or 19” rack systems. The Expert Key can also be supplied without housings to enable OEM solutions.

Providing a wide input array for a broad range of applications, the Delphin Expert Key 200 Data Acquisition System is a cost-effective solution for analog data acquisition and laboratory applications, jumpstarting projects while fitting easily into project budgets.
