Abstract
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
The present invention relates to pressure unit, specifically a kind of hydrodynamic pressure transmitter.
Background technology
Existing a kind of basic structure for measuring the hydrodynamic pressure transmitter is: the top of a pedestal has cavity, bottom has blind hole, form the strain wall between the bottom surface of blind hole and the bottom surface of cavity, the strainometer that is provided with the amplifier-chain plate in cavity and with it, joins, the strainometer docile is on the strain wall, outside the cable pass-out pedestal that the output terminal of amplifier-chain plate is connected to.This kind pressure unit in use, the pipeline that its blind hole and fluid pass through is connected, when the fluid with certain pressure enters in blind hole, the pressure-acting of fluid is on the strain wall, take into account the amplifier-chain plate by strain and pressure signal can be transformed into electric signal and output, can obtain fluid pressure value.The problem that above-mentioned existing this pressure unit in use exists is, after it is used for measuring the pressure of certain liquid, having a small amount of fluid to be measured remains in blind hole, if be used further to measure the pressure of another liquid, for not affecting the constituent analysis of another kind of liquid, need to the liquid that remain in blind hole be cleaned, what want to clean bothers, therefore, be not suitable for using on the liquid phase tester.
Summary of the invention
The object of the present invention is to provide a kind of pressure unit, this pressure unit is when the conversion detected fluid, and easy to clean and easy cleaning are thoroughly.
for achieving the above object, the present invention adopts following scheme: the fluid pressure transmitter, the top of one pedestal has cavity, the bottom of pedestal has blind hole, form the strain wall between the bottom surface of blind hole and the bottom surface of cavity, the strainometer that is provided with the amplifier-chain plate in the cavity of pedestal and with it, joins, strainometer is attached on the strain wall, the cable pass-out that the output terminal of amplifier-chain plate is connected to is to pedestal, be embedded with a plug in blind hole, have the groove that connects its edge on the upper surface of plug, the bottom of pedestal has two through holes, on plug, the two-port of groove is docked with a through hole respectively.
By such scheme as seen, groove docks with two through hole, formed a fluid passage in pedestal, while using hydrodynamic pressure transmitter provided by the invention, the pipeline that two through hole on pedestal and detected fluid are passed through is connected, during by the fluid passage in pedestal, can record the pressure of fluid in detected fluid; In addition,, by two through hole, can facilitate, the convection cell passage cleans thoroughly.
The present invention is rational in infrastructure, reliable, easy to clean, thoroughly, and it is especially suitable uses on the liquid phase tester.
