Description
Technical field
The present invention relates to sensor technical field, particularly a kind of electronic pressure transmitter.
Background technology
Pressure transducer is a kind of sensor the most conventional in industrial practice, and it is widely used in various industrial automatic control environment, relates to numerous industries such as water conservancy and hydropower, railway traffic, production automatic control, Aero-Space, pipeline.General pressure transducer is made according to Hall effect, namely Hall element is utilized to convert the displacement of the flexible member caused by pressure to Hall voltage, thus realize the measurement of pressure, but the force value that existing Hall chip pressure transducer detects is a fixing scope, design parameter cannot gather, and so just greatly reduces the scope of use.
Summary of the invention
The technical problem to be solved in the present invention there is provided one can collect force value easy-to-mount electronic pressure transmitter again.
Technical scheme of the present invention is as follows:
A kind of electronic pressure transmitter, comprise housing (1), one end of described housing (1) is provided with the first external thread column (11), also stepped hole is provided with in described housing (1), pressure chip (2) is embedded with in the macropore of described stepped hole, be installed with four-core aviation plug (3) in the aperture of this stepped hole, be electrically connected by flexible PCB (4) between described pressure chip (2) with four-core aviation plug (3); Mount pad (5) is also arranged with in the outside of housing (1) described stepped hole macropore one end, protruding second external thread column (51) of non-socket end of described mount pad (5), the end face of this second external thread column (51) external part is provided with the through hole axially running through mount pad (5), in described mount pad (5), be embedded with " O " RunddichtringO (6), described " O " RunddichtringO (6) abut fixing with the correspondence position of pressure chip (2).
Adopt above structure, the present invention when test pressure, ambient pressure surge pressure chip, then through flexible PCB electrical connection four-core aviation plug, can realize the display of force value size at output terminal, structure is simple, simple operation; Pressure chip and " O " RunddichtringO abut, and the delay effect that available buffer pressure distortion brings reduces the error of force value, also can reduce the distortion of pressure chip simultaneously, increase the service life; Housing and installation sleeve are all provided with external thread column, easy disassembly and fixing, are more conducive to test pressure data, the through hole on installation sleeve can balance or release the pressure the air pressure of chip circumference, can reduce test error.
To make moist to prevent test component or impaired, as preferably, described pressure chip (2) is columned cavity body, in described cavity body, be installed with sensor circuit board (21), be electrically connected by flexible PCB (4) between described sensor circuit board (21) with four-core aviation plug (3).
In order to improve the resistance to pressure of pressure interface, as preferably, described pressure chip (2) is made up of stainless steel material.
Beneficial effect: the present invention arranges pressure chip and exports one group of linear signal by four-core aviation plug, convenient and practical, structure is simple, easy to operate, applied widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the present invention is made up of housing (1) etc., one end of described housing (1) is provided with the first external thread column (11), also stepped hole is provided with in described housing (1), the pressure chip (2) be made up of stainless steel material is embedded with in the macropore of described stepped hole, four-core aviation plug (3) is installed with in the aperture of this stepped hole, described pressure chip (2) is columned cavity body, sensor circuit board (21) is installed with in described cavity body, be electrically connected by flexible PCB (4) between described sensor circuit board (21) with four-core aviation plug (3), mount pad (5) is also arranged with in the outside of housing (1) described stepped hole macropore one end, protruding second external thread column (51) of non-socket end of described mount pad (5), the end face of this second external thread column (51) external part is provided with the through hole axially running through mount pad (5), in described mount pad (5), be embedded with " O " RunddichtringO (6), described " O " RunddichtringO (6) abut fixing with the correspondence position of pressure chip (2).
Using method of the present invention is as follows:
As shown in Figure 1, before test pressure, the external thread column be all provided with on housing 1 and installation sleeve 5 is first utilized to fix the present invention, when ambient pressure is through installation sleeve 5 surge pressure chip 2, impulsive force makes the Hall element in sensor circuit board 21 produce Hall voltage, and forms linear data signal, four-core aviation plug 3 is electrically connected again through flexible PCB 4, just can export one group of linear signal at output terminal, structure is simple, simple operation.
When compression shock, pressure chip 2 and " O " RunddichtringO 6 abutting each other, the delay effect that available buffer pressure distortion brings, reduces the error of pressure chip 2 pairs of force value tests, also can reduce the distortion of pressure chip 2 simultaneously, increase the service life.
Arranging of first external thread column 11 and the second external thread column 51 is conveniently detachable and fixing, is more conducive to test pressure data, and the through hole on installation sleeve 5 can balance or release the pressure chip 2 ambient air pressure, also can reduce test error.
It is consistent with prior art that the present invention does not describe part.Therefore not to repeat here.
These are only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing instructions of the present invention and accompanying drawing content to do, is directly or indirectly used in the technical field that other are relevant, all in like manner within scope of patent protection of the present invention.
