| To decrease the pollution created by the dusty condition of the conveyor, Water spraying is done on the conveyor through the nozzles. when these nozzle are activated, Water is sprayed over the conveyor to settle down the dust. these nozzle are activated when the belt is in loaded condition. Hence, This belt loading monitor plays an important roll of ensuring the belt is running with the load and water is sprayed when the conveyor is running in loaded condition of the Belt. | |
| Operation : | |
| The extension stand of belt Loading Monitor is mounted in inclined position to the action of the spring. So that Rubber Roller remain upward & the proximity switch remain OFF. When the Belt is started with Load (material), The belt will press the Rubber Roller downward thereby lifting the Mechanical Flag in front of proxirnity switch. Than Proximity switch gives the signal that can be used as a sense of Belt Loading condition. This detection of the Roller is between 5mm to 30 mm | |

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.
| 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. |
for bowl liner feeders new advance version (cvcf) constant voltage, constant frequency controllers for smooth vibration and constant feed rate irrespective of change in supply voltage and frequency for genset application.
