Resistance type material level switch

1 Overview
ZY-UZK typeResistance type material level switchDetect, alarm, and automatically control powdered, granular, and block materials in open and closed silos. After long-term operation in industries such as steel, refractory, cement, rubber, chemical fibers, and electricity, ideal results have been achieved and widely used in industrial production.
2 Working principle
ZY-UZK typeResistance type material level switchAdopting a rotary transmission system. When the detection board is obstructed, the spindle is obstructed and stationary, and the motor continues to run, causing the release device to trip, resulting in the switch action cutting off the motor power supply, the motor stopping working, and issuing a level alarm signal. When the level drops, the resistance of the detection board disappears, the release device resets, the motor resumes operation, the level alarm is released, and the instrument is in the detection state again. In situations where the level changes slowly, a timer can be installed inside the instrument to keep the detection of the instrument in an intermittent working state, which can reduce power consumption and wear, and extend the life of the instrument.
