Description

A kind of pressure transducer

1, technical field:

The utility model relates to a kind of pressure transducer.

2, background technology:

At present, the structure of traditional pressure transducer as shown in Figure 1 and Figure 2, it is made up of pedestal A and pressure-active element B and lead-in wire C, pressure-active element B is installed in the end face of pedestal A, below pressure-active element B, the middle part of pedestal A has groove D, the main shortcoming of this structure is: pedestal A generally is that whole casting is come out, and then processes complex process, manufacturing time is longer, make comparatively difficulty, the material cost that it adopts is higher, expends more material.

3, summary of the invention:

The purpose of this utility model provides a kind of pressure transducer, and it improves by the structure to pedestal, makes its structure more reasonable, has simplified the manufacturing process of pedestal, has reduced manufacturing cost, and it is simple easy to make, reliable operation.

The utility model is achieved by the following technical solution: it comprises pedestal and pressure-active element and lead-in wire, pedestal comprises top board, base plate and backing plate, backing plate is between top board and base plate, and place the two ends of top board and base plate, top board, base plate and backing plate are installed together, at the top board middle part pressure-active element is installed, on pressure-active element both sides, top board, has gone out groove.

Above-mentioned described top board, base plate and backing plate are to be installed together by rivet.

The groove of going out on above-mentioned described pressure-active element both sides, the top board has 4,2 of every sides.

The groove of going out on above-mentioned described pressure-active element both sides, the top board is curved.

The utility model compared with prior art has following advantage: can make top board, base plate by sheet material easily with punch press, top board, base plate and backing plate can be installed together the formation pedestal then, processing technology is simple, selection is convenient, backing plate can select common iron plate further to reduce cost, assemble easy to manufacturely, rational in infrastructure, reduced manufacturing cost.
