The explosion-proof winch sensor is mounted on the winch shaft to monitor the angular displacement caused by the rotation of the winch shaft during the entire rig123.net' target='_blank'>drilling process. By calculating, the height change of the hook during the rig123.net' target='_blank'>drilling process can be obtained, thereby obtaining the current drilling depth. The explosion-proof winch sensor is equipped with a detection switch and a piece of iron tooth. When the tooth piece rotates with the winch shaft, the tooth piece will pass through two sampling channels of the detection switch with a phase difference of 90 ,, thereby issuing two groups. The corresponding electric pulse signal, which is sent to the instrument after identification processing, can obtain the corresponding angular displacement direction and change value.
