Product Description

Coal Mining Use Deviation Sensor

1.Summary
The device is suitable for underground coal mines, open-pit coal mines, coal preparation plants and other workplaces. It is used to detect the deviation protection signal of the comprehensive protection device of the belt conveyor.

2.Main technical parameters

Contact capacity	24VDC / 0.5A; (connected to the qualified intrinsically safe circuit)
Contact detection resistance	≤ 0.1 Ω
After vibration and impact	≤ 0.2 Ω
Action angle	30 ° ± 3 °
Reset angle	20 ° ± 3 °
Action force of probe rod	20N-100N
Boundary dimension	361mm × 158mm × 66.5mm
Weight	3kg

The sensor is a simple contact type equipment.When the sensor probe deviates from the normal position to the action angle, the two output terminals shall be connected; when the sensor probe automatically returns to the original position to reach the reset angle, the two output terminals shall be disconnected;


3.Working principle
The deviation probe rod of the sensor is located at the limit position of the allowable deviation of the belt. Normally, the belt does not contact the deviation probe rod, and the two terminals of the sensor are not connected; when the belt deviation contacts the deviation probe rod and pushes the probe rod to deviate from the normal position by 30 ± 3 °, the two terminals of the sensor are connected.

4.Structure overview
The sensor is composed of shell, deflection probe, travel switch and terminal.
