Description
Technical field
The present invention relates to industrial measuring device technical fields, more particularly to a kind of novel no cavity pressure transmitter.
Background technology
Pressure transmitter is in many industrial equipments controlling the important original paper of industrial process and pressure change.Pressure becomes
Liquid level, density and pressure of the device for measuring liquid, gas or steam are sent, pressure signal is then transformed into electric signal output,
It usually works in the environment such as high temperature low-temperature corrosion vibratory impulse, in the pressure of the industries such as oil, chemical industry, electric power, steel, light industry
It is widely used in measurement and field control general.Existing pressure transmitter built on the sand, is easy in strenuous vibration with external connection
In the case of fall off, it is heavy, be easy to block.
Invention content
In view of this, the object of the present invention is to provide a kind of novel no cavity pressure transmitter, it is in the prior art to solve
It is insufficient.
In order to achieve the above object, the purpose of the present invention is be achieved through the following technical solutions：
A kind of novel no cavity pressure transmitter, including shell are provided, the shell is built-in with the foil strain of interconnection
One end of meter and magnification circuit plate, the shell is equipped with connecting terminal, and the other end is equipped with pipe fitting, and the connecting terminal includes four
Core aviation plug, the pipe fitting are no chamber flat membrane and built-in pedestal, and sealing ring is equipped between the pedestal and the shell.
Above-mentioned no cavity pressure transmitter, wherein the length of the shell is 56mm, and the internal diameter of the shell is 25.5mm,
The length of the pipe fitting is 31mm.
Compared with the prior art, the beneficial effects of the present invention are：
Overall structure is light, flat membrane, without chamber, anti-clogging, and good airproof performance, pedestal is by being sintered, firm and durable, air plug
It is good with external connection shock resistance.
Description of the drawings
The attached drawing for constituting the part of the present invention is used to provide further understanding of the present invention, schematic reality of the invention
Example and its explanation are applied for explaining the present invention, is not constituted improper limitations of the present invention.In the accompanying drawings：
Fig. 1 shows the structural schematic diagram of the invention without cavity pressure transmitter；
Fig. 2 shows the vertical views of Fig. 1.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
With reference to shown in figure 1, Fig. 2, the present invention includes shell 1 without cavity pressure transmitter, and shell 1 is built-in with the foil of interconnection
One end of formula strain gauge and magnification circuit plate, shell 1 is equipped with connecting terminal, and the other end is equipped with pipe fitting 2, and connecting terminal includes four
Core aviation plug 3, pipe fitting 2 are no chamber flat membrane and built-in pedestal, and sealing ring 4 is equipped between pedestal and shell 1.The technical program
In, the length of shell 1 is 56mm, and the internal diameter of shell 1 is 25.5mm, and the length of pipe fitting 2 is 31mm.Using foil strain gauge essence
Degree is higher, and foil grid lateral part can make wider grizzly bar, keep transversal effect smaller, and foil grid are very thin, can be preferably anti-
The deformation of component surface is reflected, thus measurement accuracy is higher, is convenient for mass production, insulation resistance >=200M Ω/250V, another screw thread
Connector uses 7/16UNF-20.
From above-described embodiment as can be seen that advantage of the invention is that：
Overall structure is light, flat membrane, without chamber, anti-clogging, and good airproof performance, pedestal is by being sintered, firm and durable, air plug
It is good with external connection shock resistance.
Specific embodiments of the present invention are described in detail above, but the present invention is not restricted to tool described above
Body embodiment, is intended only as example.To those skilled in the art, any equivalent modifications and replacement are also all in the present invention
Scope among.Therefore, made impartial conversion and modification without departing from the spirit and scope of the invention, should all cover
In the scope of the present invention.
