LVDT displacement sensor wiring instructions:

Sensor selection Description:

LVDT displacement sensor installation instructions:

1. A margin shall be reserved for the selection of sensor range. The buffer zone of about 2.5mm at the front end of G series LVDT displacement sensor shall be avoided for installation and use.

2. Choosing the right power supply, the voltage is too high or too low to ensure the normal use of the sensor.

3、 The sensor shall be installed vertically on the detection surface, and the installation screw shall be locked after the position is adjusted.

4. G series LVDT displacement sensor has a high precision. It should be installed and used to avoid high temperature, high radiation, electrostatic interference, high frequency interference, electromagnetic interference and other interference sources, so as to ensure the detection accuracy of the sensor.

5. The sensor shield wire is well grounded.

6. Properly wired. If the wiring is wrong, the sensor may be seriously damaged.

7. The mounting bracket provided by the manufacturer shall be used as far as possible for sensor installation and fixation. If self-made clamps are required for installation and fixation, they shall be designed and installed under the guidance of the workshop technicians.
