This switch is a new device for the belt speed detection 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 along with the movement 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.The calculated value is compared with the pre-value to determine the belt number of the tape, i.e., normal speed, skid, speed, etc.At the same time, the execution circuit output the corresponding switch signal.

Structural features:

The machine is composed of touch wheel, pulse plate, electronic pulse switch, shell, etc. The touch wheel is made of pressed aluminum, the surface milling groove is wear-resistant and sliding, the shell is cast by aluminum, and the joint is equipped with sealing ring, even though the weight of the machine is reduced and the waterproof performance is better.

The internal switch of the machine is one independent normally open and one independent normally closed. If the belt speed is lower than the set speed, it can trip or stop the machine (the general setting value is between 70% and 80% of the normal value).

I. technical parameters:

Power supply voltage: AC220V detection range: 0.5m/s ~ 9.99m/s

Pulse rate: 6 ~ 120Hz speed: 0 ~ 999 RPM

Time delay: 0-60 seconds adjustable (10 seconds is set before leaving the factory) distance between the switch and the target: 10 ~ 20mm

Action delay: 0-60 seconds adjustable (factory setting: 001 seconds)

Number of switches: 1 set of normally open and 1 set of normally closed

Contact capacity: 24 ~ 380V AC/DC current 1A

Detection indicator: when the speed range is within the set range, relay output, LED luminescence can help detect the sensor or check the wiring failure
