PRODUCT INTRODUCTION
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.

PRODUCT FEATURE AND APPLICATION
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.
PRODUCT DETAILS
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. While the shade chipe is turinning with drawwork shaft, the infrared light in the gap of two photoelectric switches is guided or obstructed. Consequently, two series of voltage impulse signal is generated by photoelectric switches. The sensor is 4-wire system, defined as: +5V, 0V, signal A and signal B.
PRODUCT QUALIFICATION
All sensors either are EX type or are intrinsically safe. Zone barriers are installed in the Unit. Using well-known brand products at home and abroad, the sensors of mud logging unit have the advantage of technical and performance indicators. At the same time, the service life is long.
DELIVERY SHIPPING AND SERVICES
CNPS can ship the goods to you by Express, Air, or sea.
FAQ
1.Why do you choose our company?
We are trading company, founded a perfect oil and gas equipment product supply chain.
