Abstract
The utility model provides a pressure and temperature synthetic sensor structure. A temperature sensing part is inserted in a measurement feeler lever. The hole of the temperature sensing part, the measurement feeler lever is inserted in which, is filled with heatconducting magnesium powder; a pressure sensitive core is connected with an installation joint by laser welding. A pressure source acts on the pressure sensitive core through a pressure inlet and a pressure passage. A bakelite support is bonded to the installation joint. A signal processing circuit is bonded to the bakelite support. A shell body is connected with the installation joint by argon arc welding. Silica gel is filled and sealed in the shell body. An output lead is connected with the signal processing circuit and an output aviation receptacle. The output aviation receptacle is fixed on the shell body. The pressure and temperature synthetic sensor structure has the advantages that pressure and temperature signals can be measured simultaneously; pressure is converted into standard signals by an amplifying circuit for output; the temperature is output in the form of resistance value. The pressure and temperature synthetic sensor structure is compact, light in weight, and in the full stainless steel welded structure, which is resistant to pressure and corrosion. Silica gel is filled in the shell body, and the pressure and temperature synthetic sensor structure has excellent shock-resistance and is highly reliable. A pressure measurement orifice adopts the mode of transverse collection, and the temperature sensing part is arranged in the feeler lever.
