Mine GEJ30 type deviation sensor GEJ30

'H' Mining type deviation sensor (prototype)
< ' H' > >Mining type deviation sensor
(Prototype)
Deviation sensor It is suitable for dangerous places with explosive mixed gas methane and workplaces such as open-pit coal mines and coal preparation plants. It is used as a supporting detection device for mining belt conveyor protection devices. Monitor the deviation of the conveyor belt of the belt conveyor. When the conveyor belt of the belt conveyor deviates, the sensor outputs a low-level signal. After a delay, the protection device cuts off the conveyor control power supply to realize deviation protection. The sensor The number of installations is not limited and they are all connected in parallel.

The sensor is installed on the brackets on both sides of the belt. Normally, the belt does not contact the deviation contact rod, and the two terminals of the sensor are not connected. By
, when the belt deviation contacts the deviation contact rod and pushes the contact rod away from the normal position dd, the two terminals of the sensor are connected.
After the belt is reset,
when the deviation contact rod automatically returns to dd, the two terminals of the sensor should be disconnected.
Installation
Install the sensor on the brackets on both sides of the belt, open the sensor junction box, and use cables to connect (deviation signal), (power ground)
to the belt conveyor protection on the corresponding terminal block in the device host.
