Expert’s answer: Best method to calibrate displacement sensors?
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.
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.

Calibrating field transmitters
We have a differential pressure transmitter with a flange-mounted remote seal for measuring the liquid level in a close tank. We have a DRUCK DP610 calibrator, but we can’t calibrate the transmitter in the field. What can we do?
Unreliable density reading
Our Micro Motion Coriolis (CMF300 with 3500 RFT) doesn’t read correctly. We use it to measure the density of condensate in a custody metering skid. Now it shows 1000 kg/square centimeter, while it should read 700. How can we fix this?
