2 Sensor calibration

Calibration instruments mainly include Bentley's TK3-2E calibrator, 4-digit half digital Voltmeter, 24V DC regulated power supply and Function generator.

2.1 Sensor calibration

1. Connect the probe and the extension cable, and connect the other end of the extension cable to the proximitor. Connect the power terminal (-24VDC) and common terminal (com) of the proximitor to the -24VDC power supply, and connect the common terminal and output terminal to the digital Voltmeter.

2. Fix the probe onto the probe base with a suitable probe clamp, so that the top of the probe contacts the calibration target.

3. Send -24VDC to the power and common terminals of the proximitor, then adjust the screw micrometer on the TK3-2E calibrator to align the indicated value with 0mm, then increase the indicated value of the micrometer to 0.25mm, and record the voltage value of the digital Voltmeter (this value is the output voltage of the proximitor). Increase the gap by 0.25mm each time until the indicated value is 2.5mm, and record the output voltage value for each time (with no less than 10 verification points).

Based on the recorded data and in the form of the calibration curve of the axial displacement sensor, draw the gap voltage curve of the calibrated probe sensor system, which reflects the characteristics of the sensor.
