Remote-transmission ventilated temperature sensor

Abstract

The invention provides a remote-transmission ventilated temperature sensor. A shell has a mounting part and a probe part. A thermosensitive element and an insulating element are arranged at the inner side of the probe part; the space around the thermosensitive element is filled with thermal conductive silicone; and probes are pressed on thermosensitive element electrodes by springs. An infrared absorbing film covers the outer side of the lower end of the probe part and is arranged at the periphery of the thermosensitive element. Besides, the mounting part is provided with a main controller, a wireless communication module and a power supply; and ventilation holes are formed in the side wall of the mounting part. The remote-transmission ventilated temperature sensor provided by the invention has advantages of light weight, excellent corrosion-resistant, high-temperature-resistant, and low-temperature-embrittlement-resistant performances, and high rigidity and the like. The thermosensitive element is fixed by the thermal conductive silicone and heat conduction is realized by the thermal conductive silicone, so that sensitivity and anti-vibration performances are improved. The positive probe and the negative probe are pressed on the positive electrode and the negative electrode of the thermosensitive element under pressing by the springs; when thermal expansion and cold contraction phenomena occur at the probes, the pressures between the probes and the electrodes can be adjusted at any time by the springs, thereby realizing reliable electrical connection. A temperature value can be transmitted to a remote central control terminal wirelessly; remote monitoring can be realized; and tedious wiring is avoided.

Description

technical field [0001] The invention relates to the technical field of electrical accessories, in particular to a remote 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 ver...
