Scale for belt conveyers TPV102
| 
Processor - controlled weightometer Processo-controlled weightometer automatically weights and records the tomage of loose material in moving on a belt conveyor. The integrating weightometer consists of one sleeper bench whitch is stepped by tensometer force sensor built-in the belt conveyor. Signal from the tensometer force sensor is first amplified and then processed in RVS027E unit.
