The belt
tearing switch protects the device from the principle of electromagnetic induction, and the receiver passes The sensing coil receives the electromagnetic pulse signal generated by the generator. When the conveyor belt is longitudinally torn, the sensing coil is cut off, and the receiver will not receive the electromagnetic pulse signal, thereby generating a longitudinal tearing signal of the conveyor belt, thereby issuing an alarm signal. Stop the conveyor.
The system of the belt longitudinal tear protection device:
It consists of excitation current generator, sensor, signal processing module, single chip microcomputer, conveyor belt running distance detector, conveyor power controller and so on. The system is a real-time intelligent tear detection system designed to monitor the longitudinal tear of the conveyor belt during operation. If a tear is detected, the tear monitoring system will automatically stop the conveyor belt and determine the tearing site. The tear monitoring system works when the conveyor is activated and in normal operation. In the event of a power outage, the tear monitoring system is automatically reset when the power is turned back on. It mainly includes transmitting sensor, receiving sensor, proximity sensor, TL sensor, conversion and signal processing board, and terminal box. Check
The test signal comes from: a detection sensor for embedding a toroidal coil in a belt conveyor, and a proximity switch sensor for detecting the running distance of the tape and the rotational force of the tape is mounted on the tail or head roller of the belt conveyor
