Description
Expert Key 200 Data Acquisition System
The Expert Key 200 Data Acquisition System from Delphin Technology is simple and convenient to operate and the ProfiSignal Go software is very user-friendly. All Expert Key devices offer extensive features. The combination of all these functions into one device makes Expert Key unique in the broad field of USB data acquisition technology.
Functions of Expert Key
- Universal and flexible application
- 28 differential analog inputs
- USB and Ethernet interface in one device
- Universally usable inputs for thermocouples, RTDs, mV or mA signals
- High accuracy 18 Bit A/D converter
- Fast measurement speed (100,000 readings per second)
- Analog and digital outputs, PWM outputs, counter inputs
- Full potential isolation
- Practical: for up to 2,5 mm² lines connecting terminals
- “Made in Germany” quality
Universal Configuration
The Expert devices have full potential isolation in the form of analog differential inputs that users configure according to requirements: for mA/mV and V signals as well as for RTD or thermocouples. These universal options enable simple operation of the device.
Integrated signal conditioning enables any type of sensor to be connected to the plug-in screw terminals. Scaled measurement data is then available to users. Recalculation from mA signal to bar, % etc. is unnecessary.
The analog outputs can be easily switched between current and voltage output.
Digital inputs (status inputs with counters of up to 1MHz) and digital outputs (switch outputs, PWM-outputs) with switch capacities of up to 30W are included within the compact device and can be utilized at no extra cost or effort.
Each channel is easily configured at sampling rates of 100 KHz using the DataService / Configurator software included in delivery. To display your data on the screen, just select the required sensor, measurement range and scaling.
Full Potential Isolation
The Expert Key provides full potential isolation, a feature that is absent in many low-cost products. The analogs, with 18-bit AD converters, as well as the digitals, are galvanically isolated from the central unit (a modern FPGA) and from the PC interfaces (Ethernet/USB). Earth loops or non-isolated signals therefore present no problems and additional transformers are usually unnecessary.
Highly Communicative
As communication interfaces, the device has a USB port for plug and play operation and an Ethernet port for measurement data acquisition across company networks. Fast system set-up and mobile measurement with a laptop and the ProfiSignal Go software are therefore always possible. Fixed installations using cabinet systems are also possible.
