Comparison of measuring distances with potentiometers

Errors and signal distortion, which may arise from sensor errors and/or divergent measurements by the measuring transducer, are easy to compensate using the potentiometers on the front of the isolation amplifier.

For example, based on the installation geometry, sensors can deliver a slightly falsified measured value. Using the potentiometers to compensate the ZERO and SPAN measured distances, this kind of divergence in the percent range can be corrected, enabling the downstream devices, e.g. a PLC to obtain a correct measured value.
