Pressure sensor is to experience pressure signal, and can be converted into pressure signal according to certain rule available defeated
The device or device of electric signal out.Usually it is made of pressure-sensing device and signal processing unit.By different test pressure
Type, pressure sensor can be divided into gauge pressure transducer, differential pressure pick-up and absolute pressure sensor.It is widely used in various industry certainly
Control environment, be related to water conservancy and hydropower, railway traffic, intelligent building, production automatic control, aerospace, military project, petrochemical industry, oil well, electric power,
Numerous industries such as ship, lathe, pipeline, heavily loaded pressure sensor is a kind of in sensor, but we seldom hear this pressure
Force snesor, it is normally used in communications and transportation application, by monitor pneumatic, underloading is hydraulic, brake pressure, engine oil pressure,
Pressure, fluid power, flow and the liquid level of the critical systems such as transmission device and truck/trailer air-lock maintains heave-load device
Performance.
Ceramic pressure sensor is since the precision of measurement is more accurate, so suitability and application prospect are more extensive.But
When being the spare and accessory parts encapsulation of ceramic pressure sensor, it is highly prone to the influence of outside environmental elements, easily leads to the essence in measurement
Accuracy decline.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of encapsulation knot of pressure resistance type ceramic pressure sensor
Structure solves the influence for being highly prone to outside environmental elements when encapsulation in the prior art, easily leads to the precision in measurement
The technical issues of decline.
In order to achieve the above object, the utility model is achieved by the following technical programs：
A kind of encapsulating structure of pressure resistance type ceramic pressure sensor, including upper cap tube, lower cap tube, the lower cap tube with it is described
Upper cap tube is in mating connection, forms cavity in the middle part of the upper cap tube and lower cap tube, the inner top of the upper cap tube passes through spring base
