Detailed Product Description
The sensor is used to measure the drilling depth parameter. The explosion-proof drawworks sensor is internally fitted with detector switches and an iron blade. When rotating with the drawworks shaft, the blade will pass through the sampling channel of the two detector switches of 90° phase difference respectively, which thus sends out two groups of corresponding electrical pulse signals. After the signals are identified and processed by the instrument, the corresponding angular displacement direction and variation value can be obtained. After calculated, the hook height variation and thereby the current drilling depth during drilling can be obtained.
