Inserted telemetering type temperature sensor

Abstract

The invention provides an inserted telemetering type temperature sensor. A housing is composed of a mounting part and a probe part. The inside of the probe part is provided with a temperature-sensitive element and an insulating member. Heat-conductive silica gel is arranged at the periphery of the temperature-sensitive element. Probes are pressed on the electrodes of the temperature-sensitive element through springs. An infrared ray absorption film covers the lower end of the probe part. The infrared ray absorption film is arranged outside the temperature-sensitive element. The mounting part is provided with a master controller, a wireless communication module and a power supply. According to the inserted telemetering type temperature sensor, the probe part is made of a heat-conductive carbon fiber material; the heat-conductive carbon fiber material has advantages of small weight, high corrosion resistance, high strength, remarkable high-temperature resistance, remarkable low-temperature brittle rupture resistance, etc.; the heat-conductive silica gel is utilized for fixing the temperature-sensitive element and conducting heat, thereby improving sensitivity and vibration resistance; a positive probe and a negative probe are respectively pressed on a positive electrode and a negative electrode of the temperature-sensitive element through pressures of the springs; once an expansion-with-heat and contraction-with-cold of the probe occurs, the spring can adjust the pressure between the probe and the electrode at any time, thereby realizing reliable electric connection; a temperature value can be wirelessly transmitted to a remote central control terminal; and remote control without tedious wiring is realized.

Description

technical field [0001] The invention relates to the technical field of electrical accessories, in particular to a plug-in remote temperature sensor. Background technique [0002] A temperature transducer is a sensor that can sense temperature and convert it into a usable output signal. [0003] At present, in the market, the protection tube of the temperature sensor is made of metal tube, ceramic tube or metal tube surface coating and other materials, but the temperature resistance range of the metal tube does not exceed about 1200 ° C for a long time, and the corrosion resistance range is also limited, such as alkali, For hydrochloric acid medium, metal pipes are difficult to solve the problem of corrosion resistance. If precious metal materials are used for corrosion protection, the cost is very expensive; although ceramic pipes (including corundum pipes) can resist corrosion and withstand a certain range of high temperatures (about 1600 ° C), but not only It is very easy...
