The temperature chamber of body of behaveing affectedly connection；The Ceramic sensible devices are assemblied in ceramic support seat cavity, and ceramic support seat is assemblied in biography
In sensor installation cavity body, ceramic support seat is equipped with the second pressure chamber that cooperation is connected to First pressure chamber；Ceramic support seat with
Temperature chamber corresponding position is equipped with inserted sheet, and thermistor is located in temperature chamber, and is welded on inserted sheet；Terminal assembly and the sensitive member of ceramics
Part, thermistor electrical connection.
Preferably, the first O-ring seal is equipped between the Ceramic sensible devices and ceramic support seat.
Preferably, step is equipped at the interior side port of the First pressure chamber, step is provided with the second O-ring seal.
Preferably, the exterior side port of the temperature chamber is closed, and has poured into heat-conducting silicone grease in temperature chamber.
Preferably, the ceramic support seat interior design contact pin, contact pin top are welded with connection soft board, contact pin lower part with
Inserted sheet welding；It connects soft board one end and welds terminal assembly, other end welding ceramics sensing element.
Preferably, the ceramic support seat is equipped with the boss for protruding into temperature chamber.
Preferably, the boss and temperature chamber clearance fit.
Preferably, the First pressure chamber is the step through-hole that outside sectional area is greater than inside cross-sectional product；Second pressure
The sectional area of inside of sectional area and First pressure chamber of chamber is identical.
The utility model is the beneficial effects are as follows: compared with traditional air conditioning pressure temperature sensor, the utility model
Air conditioning pressure temperature sensor change traditional two sensors of use and meet measurement pressure and temperature, thermistor with
Inserted sheet welding on ceramic support seat, the installation of thermistor inductive head are inoculated with the thermally conductive of high thermal conductivity coefficient in the housing, in shell
Silicone grease, thermistor inductive head and solder joint are not contacted with measuring medium, the strong acid oxidation for avoiding the fluorine-containing material in medium from generating
Solder joint.
The utility model has the characteristics that structure simple, good appearance, with short production cycle, thermally conductive fast accurate, with tradition
Pressure-temperature sensor compare, temperature chamber is separated with pressure cavity, and the solder joint of thermistor is not by the pollution of pressure medium, tool
There is thermally conductive fast, the stable advantage of performance.
