ZL longitudinal tear protection 
 Vertical longitudinal tear tear protection monitoring device protection 
 ZL longitudinal tear protection device is mainly used to detect the vertical conveyor belt tear down the letter it sent in time to prevent the accident from tearing. Main technical indicators: control of switching capacity: AC380V 2A control switch output contacts: normally open contacts 1 double, 1 NC Operating force: 70 ~ 110N output delay: 1 ~ 8 seconds (adjustable) Protection grade: IP65 operating principle: ZS -1 type longitudinal tear bar cable detector, installed on the feeder section intermediate buffer roller under the belt, the normal state, the bar claims in state of equilibrium, when a foreign body piercing the tape stopped pulling cable, the pulling of the output signal to control room alarm or shutdown. ZS-G-type photoelectric detector longitudinal tear, which is squeezed by the sensor, when the tape was, after penetrating the material, or material activities blocked the door extrusion pressure sensor, the signal sent to the control room rent, the alarm or shutdown .
