SK-8J06 Explosion-proof Drawworks Sensor
| SK-8J06 explosion-proof drawworks sensor is installed on the drawworks shaft and it can monitor the angular displacement generated by the rotation of drawworks. Changes in hook height during drilling can be obtained through calculation, thus the current drilling depth can be obtained. The detector switch and a ferruginous blade are installed inside the sensor. When rotating with the drawworks shaft, the blade passes through the sampling channel of two detector switches with phase difference of 90° to send out two groups of corresponding electric pulse signals. |
