2 Channel Ethernet-Sensor-Interface SI-ETH with freely available Configuration and Evaluation Software VS2. The Evaluation and Excitation of the connected Sensor occurs via the Ethernet Interface of the PC. Sensors with Output Signals of mV/V, ±5V, ±10V or 0/4 … 20 mA are suit­able for the Connection. Through the Measuring Rate of up to 2500/s, high-dynamic Measure­ments are realizable. This Measuring Amplifier is also very suitable for heavy Industry Applications by its robust Aluminum Die Cast Housing.

Via the sensor interface SI-ETH, a sensor is connected to a PC through an IP-based Ethernet. By this, analog sensor signals with up to 16 bit resolution are digitized.
By a measuring rate of 2500 measurements/sec per channel, highly dynamic measurements are possible as well. The measured val- ues are transferred to a PC via the Ethernet interface and are visualized through the software.
If a control signal is integrated in the sensor, an automatic adjustment can be carried out, which is checkable at any time (monitoring of the measuring chain).
Many commercially available sensors such as force-, torque-, displacement- or pressure sensors can be used with the SI-ETH. The sensor parameters can be stored in the SI-ETH. After a once-only parameterization, each sensor is automatically recognized by the software.
The voltage supply of the SI-ETH occurs via an external power supply unit or with PoE via the network cable. Through the measuring amplifier, the connected sensors are directly supplied with voltage, so a separate supply of the sensors is omitted.
Unwanted frequencies are filtered with the second-order low-pass filter. Here, 4 different limit frequencies are selectable. The connection to LabVIEW or the integration into your own programs is possible with the freely available driver package.
