The content of the invention
The purpose of this utility model is to provide a kind of TO gauges sensor, for testing relative pressure, the sensor
Pedestal is made up of base sleeve and base body two parts, parts processing, and two-part structure is all very simple, thus processing technology letter
It is single, save machining process cost.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of TO gauges sensor, including base body, base sleeve, pressure chip, acupuncture needle, presser sensor diaphragm, pressure
Ring, gauge pressure pipe, base body are weldingly fixed in base sleeve, and acupuncture needle is fixed through base body and by glass insulator, acupuncture needle
Upper end connects pressure chip by acupuncture needle wire；Gauge pressure pipe is fixed on base body also by glass insulator, and pressure chip is put
In the upper end of gauge pressure pipe latus rectum；Presser sensor diaphragm is encapsulated in the upper end of base sleeve by pressure ring.
Seal groove is provided with the outside of the base sleeve, the lower surface of base sleeve inner chamber is provided with the tip projection of annular,
The projection is welded and fixed with base body, and the upper surface of base sleeve is additionally provided with silicon oil infilling chamber.
The base body is circular sheet-like structures, and acupuncture needle mounting hole is provided with base body.
Compared with prior art, the beneficial effects of the utility model are：
The utility model provides a kind of TO gauges sensor, for testing relative pressure, by baroque one
Body pedestal is divided into two parts simple in construction, and carries out machining process respectively, is then welded and fixed by stored energy welding.Two
The structure divided is all very simple, thus processing technology is simple, the man-hour saved during machining process cost, and sensor production
And cost of labor.
Base sleeve is simple in construction, and inner chamber does not need excessive hole milling to finish, and simplifies machining process technique, reduces system
Make cost.
Base body structure is more simple, and its overall structure is sheet, individually carries out hole milling processing, and mechanical processing technique is more simple
It is single, it can effectively reduce cost of manufacture.
In addition, base body can be installed according to the supporting selection of the model of pressure sensor pressure chip, and base sleeve can be with
Using unified standard model, the processing and assembling for making sensor are all standardized, also saved while processing cost is reduced
Man-hour and cost of labor during sensor production.
