Pressure gauge, main component have watchcase, Bourdon tube (i.e. bourdon tube), linkage magnification system, balance spring, scale etc., and the one of Bourdon tube
End is fixed, and one end activity, cross sectional shape is noncircular cross section, and Bourdon tube is gradually expanded into circle under the action of pressure inside it
Shape, the displacement of movable end generation at this time and pressure size can measure pressure based on the displacement of Bourdon tube at certain relationship.
Existing pressure gauge generally passes through transmission amplification mechanical mechanism and the displacement of Bourdon tube is converted to the rotation of pointer, using pointer come
Corresponding pressure is indicated, this structure is unable to fully reflection Bourdon tube since mechanical part itself has transmission and rigging error
Displacement information, therefore there is a problem of that accuracy and sensitivity is not high.
There are also the digital pressure gauges based on pressure sensor for the prior art, are turned pressure signal using pressure sensor
It is changed to electric signal, and is corresponding pressure value by Electric signal processing.Digital pressure meter accuracy is higher, sensitive to pressure change,
But its anti-impacting with high pressure ability is not so good as bourdon tube pressure gauge, limits the use scope of digital pressure gauge.
The object of the present invention is to provide a kind of pressure meter structures for summary of the invention, to solve the prior art based on Bourdon tube
The low problem of pressure gauge accuracy and sensitivity.
In order to achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of pressure meter structure including the shell that watchcase and dial plate are constituted, and is arranged in the intracorporal Bourdon tube of shell, Bourdon tube
Fixing end is connected with the interface tube being pierced by from watchcase, it is characterised in that: closed chamber, closed chamber position position are equipped with inside watchcase
