Abstract
Utility model discloses a kind of novel pressure sensor elastomer, it is characterised in that: a kind of novel pressure sensor elastomer, the cylindrical shape being made by metal material.Novel pressure sensor elastomer upper end is elastic surface, and the elastic surface is ground, after polishing, can make the film resistor of measuring medium pressure.Lower center portion offers horn mouth, and the horn mouth lower part is big, top is small, and measuring medium is not easy to plug.Novel pressure sensor elastomer lower end edge is machined with supporting table, and the supporting table top is machined with stress relief grooves, and the stress relief grooves top is machined with support edge.Due to being machined with the horn mouth that lower part is big, top is small in elastomer lower part, measurement viscous medium is not easy to plug, it is ensured that precise measurement.
Description
Technical field
The utility model relates to a kind of pressure sensor elastomers more particularly to a kind of lower part to be machined with and be not easy to plug medium
Bell-mouthed novel pressure sensor elastomer.
Background technique
Sputtered thin film pressure transducer is a kind of pressure sensor of function admirable, it has, and precision is high, stability it is good with
And measuring medium temperature it is high the advantages that, in many such as Aeronautics and Astronautics, military project, nuclear industry, petrochemical industry, traffic, metallurgy, food, medicine
Field is applied.
But the elastomer medium measuring point opening of sputtered thin film pressure transducer is smaller, and not flare shape, easily
Measuring medium is blocked, it is even more so to the biggish medium of viscosity, influence pressure sensor measurement accuracy.
Therefore, it develops a kind of lower part and is machined with and be not easy to plug the bell-mouthed novel pressure sensor elastomer of medium extremely
It is important.
Summary of the invention
The bell-mouthed novel pressure for being not easy to plug medium is machined with the purpose of this utility model is to provide a kind of lower part
Sensor elastomer realizes the precise measurement to viscous medium in view of the deficiencies of the prior art.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of novel pressure sensor elastomer,
Be characterized in that: novel pressure sensor elastomer upper end is elastic surface, and lower center portion offers horn mouth, lower end edge
Along supporting table is machined with, the supporting table top is machined with stress relief grooves, and the stress relief grooves top is machined with support edge.
The horn mouth lower part is big, and top is small, and measuring medium is not easy to plug.
The elastic surface is ground, after polishing, can make the film resistor of measuring medium pressure.
Compared with prior art, having the beneficial effect that possessed by the utility model is not influencing any performance of elastomer
Under the premise of, it is machined with the horn mouth that lower part is big, top is small in elastomer lower part, measurement viscous medium is not easy to plug, it is ensured that essence
Really measurement.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of the novel pressure sensor elastomer of the utility model.
In figure: 1, elastic surface, 2, horn mouth, 3, supporting table, 4, support edge, 5, stress relief grooves.
Specific embodiment
As shown in Figure 1, a kind of novel pressure sensor elastomer, the cylindrical shape being made by metal material.It is described
Novel pressure sensor elastomer upper end is elastic surface 1, and the elastic surface 1 is ground, after polishing, can make measuring medium pressure
Film resistor.Lower center portion offers horn mouth 2, and 2 lower part of horn mouth is big, top is small, and measuring medium is not easy to block up
Plug.Novel pressure sensor elastomer lower end edge is machined with supporting table 3, and 3 top of supporting table is machined with stress and releases
Slot 5 is put, 5 top of stress relief grooves is machined with support along 4.
When medium is acted on the elastic surface 1 by horn mouth, the film resistor on the elastic surface 1 occurs
Deformation output electric signal corresponding with pressure.
Due to being machined with the horn mouth that lower part is big, top is small in elastomer lower part, measurement viscous medium is not easy to plug, really
Protect precise measurement.
The above is only the better embodiment of the utility model, is not construed as the limit to the scope of the utility model
System, and the scope of the claims that the utility model is advocated is not limited thereto, all personages for being familiar with this field skill, according to
Technology contents disclosed by the utility model, can think easily and equivalence changes, the protection scope of the utility model should all be fallen into
It is interior.
