It’s easy to calibrate displacement sensors. Still, you need a special tool. Google “proximity probe calibrator” and you should find a few options. Once you get your calibrator, you can set up your sensor simulation and check your displacement probe.
Calibrating a displacement sensor
Some calibrators can read sensor data directly. Some need a multimeter to read the millivolts. Either way, make sure you compare the probe measurement with the probe output, using the datasheet.
Install the displacement probe on your calibration station. The station can simulate different distances to verify the output, but the output must be within the limits on the datasheet. Also, remember to calibrate the station and the multimeter before calibrating the probe to validate your data.
