Depth sensor

Wireless draw work sensor for mud logging unit Wireless draw work sensor used to measure the depth of the well, the time of drilling, the position of the drill bit, the height of the hook, the speed and the direction of motion. The draw work sensor is the most important sensor in the comprehensive logging instrument. It is mainly used to measure the depth of the well, the time of drilling, the position of the drill bit, the height of the hook, the speed and the direction of motion. The performance of the winch directly affects the quality of the logging data and the oil and gas exploration work. The draw work sensor is composed of stator and rotor. The super miniature double pulse probe lies flat in the stator slot. When the rotor rotates, the magnetic sensor on the turntable continuously sweeps over the surface of the probe, so two groups of pulse signals with phase difference are obtained at the output end, which are transformed into two groups of counting pulses through the interface circuit and sent to the instrument for processing. Through the real-time data detection of winch signal, the winch pulse signal count value related to the hook height can be obtained. Through the output of two winch sensors, the running direction can be judged. These data can be transmitted to the upper computer, and the real-time well depth can be obtained through the corresponding calculation. The sensor is designed to measure well depth and hook position. Within the sessor, it is equipped with two photoelectric switches and a shade chip with dental flake.
