' H' Mine Coal Heap Sensor Coal Heap Protection Sampling is realized by coal level sensor

Coal Heap Protection Sampling is implemented by the coal level sensor. Normally, the output end of the coal level sensor outputs a high level. When the coal level increases and the sensor deflects to a certain angle, the universal contact inside it conducts and outputs a low level, and the full coal indicator light illuminates. After a short period of time, the coal level sensor outputs a high level. After the delay, the host performs relay release to realize coal pile protection and simultaneously sends out a verbal alarm signal. The principle of the electrode type coal level sensor is the same. When the electrode contacts the coal pile, when the coal resistance is less than 100%, after a second delay, the machine will shut down due to failure and protect the belt. Jining Dongda

When the belt conveyor is operating normally, the contacts of the mechanical push-type coal stacking sensor are offset by ~d or when two electrodes are in contact with coal at the same time, the belt conveyor is delayed by ~ seconds. The machine should be shut down, the coal stacking indicator light on the main unit of the monitor will light up, and a loud coal stacking verbal alarm will sound at the same time. Coal pile sensors for coal mines, coal level sensors for mines, and coal pile level protection.
