2, working principle

When the UL type resistance shift type bit meter detecting plate is blocked, spindle stop transferred, the motor continues to run, pressure to drive the shift fork open resulting in fretting switch, relay contacts conversion cut off power from the motor, the motor stops working, to send out the switch quantity signal (instrument adopts the double pole double throw switch quantity signal). When the material level drops, the detection board resistance disappears, and the pressure is reduced by the spring force, the relay contact is switched on the motor power, the motor works, the instrument recovery operation state.
