Model CL-WD11 temperature sensor is used to measure temperature indirectly by the change of some sort of feature of the thermometric materials with the change of temperature. At the logging working site, the temperature sensor is used to measure the temperature of the cuttings carrying out from the bottom hole as well as temperature of the drilling fluid carrying possible hydrocarbon. Owing to the stainless steel structure is used for the joint lever, protect jacket and temperature sensing probe, the joining part is sealed with mechanical and oil proof sealing; the temperature sensing part is made of a thick film platinum resister; the sensor has features of good anti-corrosion, good tightness, good linearity, stable performance and short response time.
