Product description:
This speed detector is a new device used to detect the belt speed of conveyor. It can detect the belt speed in real time. It has been widely used in the belt conveyor system, providing reliable detection means for the safe operation of the belt conveyor.The conveyor bracket between the upward rubber belt and the downward rubber belt should be installed horizontally, so that there is a certain pressure between the contact wheel and the belt surface to prevent the wrong action caused by the beating of the contact wheel.When the contact wheel drives the inner pulse disk with the operation of the belt conveyor, the magnetic response signal of the sensor is input into the control circuit when the pulse hovers, which is amplified and then counted.Its value is compared with the preset number to determine the belt speed, i.e., normal speed, skid, speed, etc.At the same time, the execution circuit outputs corresponding switching signals.
Structural features:
1. The machine is composed of touch wheel, pulse plate, electronic pulse switch and shell
The contact wheel is made of cast iron
The shell adopts aluminum casting, and the joint is equipped with sealing ring, which can effectively reduce the weight of the body and obtain better waterproof performance.
2. The internal switch of the machine is normally closed. If the belt speed is lower than 80% of the normal speed, it can trip or stop.
