Belt Tear Switches

 
To Detect Torn Belt Condition & Provide Tripping Operation
Location of Monitoring Units
 
The monitoring units are to be fixed in inclined position in the direction of the belt rnovement.

The unit is provided with two 5meter long rope lengths. Appropriate length to be cut while fixing the rope. The splinters, resulting from tearing of the belt, will push out the cross connected sensing rope to acuate the switch. The potential free contacts of the switch are to be wired into appropriate warning/tripping circuit. The switch can be reset by operating the reset lever. Rope to be rnanually refixed in position while re-starting the belt operation.

Belt Tear/Rupture Switch
To Detect Torn/Rupture Belt Condition

Sai Control System offers new generation Belt Rupture/Rip switch which is based on advanced micro controller technology. Belt rupture Switch consist of controller and optical transmitter and receiver for sensing. Sensor to be mounted below the belt of the conveyor. If the belt is ruptured or ripped then the conveying material will fall in the sensing area of the sensor and it will sense the falling material and the controller will trip the belt conveyor.

Contact : 1c/o/2c/o
Output Indications : Through LEDs
Restart : Automatic / Manual
By Pass : Provided for bypass
Max Range : Adjustable up to 3 mtrs
