Evaluation unit and software
The evaluation unit SPP-3001 assumes complete signal conditioning of the sensor signal and calculation of the measured distance. The calculated distance or angle information is scaled to 0-10 V as analog output voltage and emitted at the BNC output.
The SPP-3001 has a high sampling frequency (1 MHz) and can be expanded to 32 measuring channels. The valve position is measured within 1 μm in real time and output as analog voltage. This means that even very fast movements can now be detected reliably.
Before the start of measurement, the system is configured and calibrated in just a few steps. A graphic user interface is provided for this purpose. The evaluation unit communicates with a Windows PC via USB during the setup phase. After switching to the "measure" mode, the analysis operates autonomously and there is no need for a connection to the PC. The "setup" and "measure" modes are each displayed on the evaluation unit with an LED.
The software offers the following setting options:
- Automatic and manual adjustment to sensor offset and sensor amplitude
- Amplification setting
- Adjustment to the tooth pitch of the measured distance
- Real-time signal monitor during setup phase
- DAC test
- Selection of communication interfaces (virtual COM ports)
