1. Product use GVH100 mine-used intrinsically safe tear sensor (hereinafter referred to as the sensor) This standard applies to mine-used intrinsically safe tear sensor. The sensor is suitable for working places such as underground coal mines, open-pit coal mines, coal preparation plants, etc., as a protection against longitudinal tearing of belt conveyor belts.
2. Features 2.1. The product has simple wiring, reduces explosion points and is easy to maintain;
2.2. Mining intrinsically safe tearing sensor sensor has high sensitivity;
2.3. The product adopts infrared technology, which is advanced and reliable.
3.Electrical performance Rated working voltage: 12VDC;
Working current: ≤900mA;
3.1. Maximum infrared receiving distance: ≤100cm;
3.2.Relay contact output: a normally open;
3.3. Electric shock capacity: DC24V/0.5A (resistance to non-sexual load)
3.4. Action performance
Set the infrared transmitter and receiver at a distance of ≤100cm, and then turn on the power. When there is no cover, the relay output of the receiver is disconnected; when there is a cover, the relay output of the receiver is closed.
3.5. Maximum transmission distance
The maximum transmission distance between the sensor and the host ZJZ-IS-Z is 1km.
3.6. Infrared light emission power ≤150mW.
