Abstract
The present invention is a kind of ultra micro differential pressure table structure, it includes a shell, the shell is equipped with one or more connector, each inner end of the joint is connected to a chamber being located in shell, the chamber, which more reconnects, a pressure element and the pressure element is set on a circuit board, and especially the pressure element is set to the exterior thereto with the circuit board.Whereby, the ultra-miniature pressure is in continuous mode, because the chamber and the pressure element and circuit board are in isolated relation, therefore pressure will not be influenced by the operating temperature of the electronic components such as the pressure element or circuit board and cause error completely, and the pressure value determined can be made to obtain accurate purpose.
Description
Technical field
Ultra micro differential pressure table structure of the present invention, be related to it is a kind of can to adherence pressure table measure Numerical accuracy, reduce miss
The technical field of difference.
Background technology
Civil many industrial equipments or equipment, are generally both provided with pressure gauge, its role is to measure and show inside stream
The pressure of body.Conventional pressure table is all pointer-type, such as oil pressure gauge, is internally provided with Baden pipe, can be made using pressure change
Baden pipe deformation, and then indicators turn is interlocked, to coordinate scale plate to show numerical value on panel.It is to avoid numerical value artificial in recent years
Read error, and to meet the demand that pressure value is automatically transmitted to the whole information of cruise Control Module remittance, many pointer-type pressures
Power table is slowly replaced by electronic digital type pressure gauge.Though this kind of electronic digital type pressure gauge can directly display pressure value and
Tool automatically delivers the function of numerical value, but because its internal electronic component has an operating temperature at work, which will
The pressure value accuracy positioned at pressure gauge internal chamber can be seriously affected, it is poor in the high ultra micro of precise requirements especially to apply
When pressure gauge, being even more impermissible for any external factor influences the accuracy of pressure value.Obviously, existing electronic digital type ultra micro is poor
Pressure gauge is faced with this problem to be resolved.
There are above-mentioned missings in view of existing structure by inventor, and the rich experiences of the sector are engaged according to accumulation many decades,
Application with the domestic and international patent of more than one piece and the experience of acquirement join hands to seek solution, have ultra micro differential pressure table knot of the present invention eventually
The completion of structure.Inventor's hope can use up one's own by the proposition of this case, contribute the ability feedback of itself in industry
Boundary.
Invention content
For the electronic component inside the existing electronic digital type pressure gauge of solution, operating temperature can cause error at work
Missing, ultra micro differential pressure table structure of the present invention, main purpose are：The internal structure of the pressure gauge is improved, can solve to survey
The problem of fixed pressure value is influenced by electronic component operating temperature makes the measurement numerical value of pressure be avoided that error, obtains accurate
Purpose.
In order to achieve the above object, the present invention provides a kind of ultra micro differential pressure table structure, include a shell, which is equipped with
One or more connector, each inner end of the joint are connected to a chamber being located in shell, which, which more reconnects, has
One pressure element, each pressure element are set to the exterior thereto.
In one embodiment of the present of invention, wherein the pressure element is set on a circuit board.
In one embodiment of the present of invention, a continued access element is wherein provided between the connector and the chamber.
In one embodiment of the present of invention, wherein the chamber interior is formed with an enclosure space.
In one embodiment of the present of invention, wherein a connecting element is provided between the chamber and the pressure element.
Ultra micro differential pressure table structure of the present invention avoids influence of the temperature to the pressure value of measurement, makes piezometry numerical value more
Accurately, error is reduced.

【Symbol briefly describes】
1 pressure gauge, 10 shell, 11 connector
12 continued access element, 13 chamber, 14 enclosure space
15 connecting element, 16 pressure element, 17 circuit board
18 panels.
Specific implementation mode
The hereby careful just structure composition of ultra micro differential pressure table structure of the present invention and its it is produced the effect of, coordinate schema, act one
Detailed description are as follows for the preferred embodiment of this case.
Head please refers to Fig.1, Fig. 2 as shown in figure 3, this case " ultra micro differential pressure table structure ", which includes a shell
10, which is equipped with one or more connector 11, which is connected to one and is located in shell 10
Chamber 13, which, which more reconnects, a pressure element 16 and the pressure element 16 is set on a circuit board 17, especially
Each pressure element 16 is set to each circuit board 17 outside the chamber 13；It is continuous that one is provided between the connector 11 and the chamber 13
Element 12 is connect, and is formed with an enclosure space 14 inside the chamber 13, and is provided between the chamber 13 and the pressure element 16
One connecting element 15.
The quantity of the above-mentioned chamber 13 is preferred with two, and one of chamber 13 is used to measure positive pressure, another chamber
13 are to measure negative pressure use.
It is provided with a panel 18 on the above-mentioned shell 10, which can be showing the pressure measured by the pressure element 16
Power numerical value.
Through each connector 11 is connected to source pressure to be measured, fluid enters chamber 13, last profit by the connector 11
The pressure value is measured with the pressure element 16, and then is shown on the panel 17.Due to this case each pressure element 16 with
Circuit board 17 is all set to outside the chamber 13, so even the pressure element 16 has the liter of any operating temperature with circuit board 17
Drop, will not all have any impact to the pressure state inside the chamber 13, be avoided that error, keep pressure value accurate, when answering
For the measurement of ultra micro differential pressure, there is progressive really.
In conclusion ultra micro differential pressure table structure of the present invention does not have violation is any cannot obtain according to existing patent statute
The facts of patent right.This case is industrially utilized really, had not been seen publication before application or had openly been used, and non-for public affairs
The technology that crowd knows.Furthermore this case effectively solves the problems, such as there is and reach associated user in prior art for a long time and disappear
The long-term demand of the person of expense, must prove the present invention can not be readily accomplished.
Though the present invention is described by previous embodiment, but still can change its form and details, in not departing from the present invention's
Spirit and reach, and the personage by being familiar with this skill can be appreciated that.The preferred embodiment of aforementioned this case only borrows this case principle can be with
One of mode of specific implementation, but be not limited thereto system, should be defined according to claim subject to.
