Abstract

The invention provides a plug-in vented temperature transducer. A shell is divided into a mounting part and a probe part; the inner side of the probe part is provided with a thermosensitive element and an insulating element; filling of thermal-conductive silica gel around the thermosensitive element is realized; a probe is pressed onto an electrode of the thermosensitive element through a spring; the lower end of the probe part is covered with an infrared absorption film; the infrared absorption film is located on the periphery of the thermosensitive element; and vent holes are arranged in the side wall of the mounting part. The plug-in vented temperature transducer has the advantages that the structure is simple and the design is reasonable; the thermal-conductive carbon fiber material is adopted as the probe part, and advantages of light weight, corrosion resistance, ablation resistance, high hardness, wear resistance, high temperature resistance, low temperature embrittlement resistance and the like are realized; the thermal-conductive silica gel fixes the thermosensitive element and conducts the heat, and the sensitivity and the anti-seismic performance are improved; a positive probe and a negative probe are pressed onto the positive electrode and the negative electrode of the thermosensitive element under pressure of the spring, when a thermal expansion and contraction phenomenon happens to the probe, the spring can randomly adjust the pressure between the probe and the electrode, and reliable electrical connection is realized.

Description

technical field [0001] The invention relates to the technical field of electrical accessories, in particular to a plug-in air-permeable 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 ve...
