user's guidance
1. Principle
The non-contact eddy current displacement sensor is based on the “eddy current effect†of a high-frequency magnetic field on a metal surface.
It is an ideal sensor for the detection and control of mechanical quantities such as displacement, vibration and rotation speed of objects. It has non-contact measurement, wire
Wide range, high sensitivity, strong anti-interference ability, no medium influence, stable and reliable, easy to handle and other obvious advantages, extensive
It is used in metallurgy, chemical industry, aerospace and other industries, as well as displacement, vibration, rotation speed, length,
Detection of mechanical quantities such as thickness and surface unevenness.
At present, our company produces two types of eddy current sensors: displacement, vibration sensors and speed sensors.

5. Connection and calibration of displacement sensors
1. Connection of sensor and pre-converter
â‘ Connect by high-frequency cable, the standard length is 3 meters.
â‘¡ The maximum length can be extended to 9 meters, which needs to be explained when ordering.
2. Calibration of sensor and pre-converter
①Environment: room temperature 20 ± 5 ℃
② Material: 45 ﹟ steel (user can specify the material to be tested)
③ Equipment: static calibrator 0-25mm ± 0.005
(Users can choose our company's static calibrator to calibrate by themselves.)
â‘£, static calibrator:
The static calibrator is customized by a high-precision micrometer and a special bracket. It is used for the static calibration and calibration of the sensor to obtain the input-output characteristic curve of the sensor. Standard output. The relative distance between the sensor and the measured body can be adjusted by adjusting the nut, and the static calibration or calibration of the displacement can be performed with a micrometer.
⑤ Calibration method
Place the sensor on the chuck of the static calibrator and place the test piece on the test piece bracket. The test piece must be selected according to the actual material and shape of the test body. The four-core connector of the pre-converter is connected to the power supply and digital Connect the multimeter correctly and turn on the power to make the pre-converter work normally. Change the adjustment nut of the static calibrator to make the sensor slightly contact with the test piece, adjust the "full scale" potentiometer to a smaller position, and then adjust the micrometer according to the lower limit point of the linear range provided in the output characteristic table of each sensor , Change the distance between the sensor and the test piece, and then adjust the "zero" potentiometer so that the lower limit output of the converter reads "0V" (if it is ± 5V output
