Problems solved by technology
The problem with the above-mentioned existing pressure transmitter in use is that when it is used to measure the pressure of a certain liquid, a small amount of the measured liquid will remain in the blind hole, and if it is used to measure the pressure of another In order not to affect the composition analysis of another liquid, it is necessary to clean the liquid remaining in the blind hole. It is more troublesome to clean it thoroughly. Therefore, it is not suitable for use on a liquid phase tester.

The invention discloses a pressure transmitter. A cavity is formed in the upper part of a base body; a blind hole is formed in the bottom end of the base body; a strain wall is formed between the bottom surface of the blind hole and the bottom surface of the cavity; an amplifier circuit board and a strainometer connected with the amplifier circuit board are arranged in the cavity of the base body; the strainometer is attached to the strain wall; a cable connected to an output end of the amplifier circuit board is led out of the base body; a plug is mounted in the blind hole in an inserting manner; a groove penetrating through the edge of the plug is formed in the upper end surface of the plug; two through holes are formed in the lower part of the base body; and two ports of the groove in the plug is in butt joint with one through hole respectively. The groove is in butt joint with the two through holes, and a fluid channel is formed in the base body; when the fluid pressure transmitter is used, the two through holes in the base body are communicated with tested fluids through pipelines; when the tested fluid passes through the fluid channel in the base body, the pressure of the fluid is measured; besides, by means of the two through holes, the fluid channel can be cleaned conveniently and thoroughly.
Description
technical field [0001] The invention relates to a pressure transmitter, in particular to a fluid pressure transmitter. Background technique [0002] An existing basic structure for measuring fluid pressure transmitter is as follows: the upper part of the seat has a cavity, and the bottom end has a blind hole, and a strain wall is formed between the bottom surface of the blind hole and the bottom surface of the cavity. An amplifier circuit board and a strain gauge connected with it are provided, the strain gauge is attached to the strain wall, and the cable connected to the output terminal of the amplifier circuit board passes out of the seat body. When this kind of pressure transmitter is in use, its blind hole is connected to the pipeline through which the fluid passes. When the fluid with a certain pressure enters the blind hole, the pressure of the fluid acts on the strain wall. The pressure signal is converted into an electrical signal and output to obtain the fluid pre...
