Abstract
Provided is a pressure transmitter. A cavity is disposed on an upper part of a base. A bottom end of the base is provided with a blind hole. The bottom surface of the blind hole and the bottom surface of the cavity form a strain wall. An amplifier circuit board and a strain gauge connected with the amplifier circuit board are disposed in the base. The strain gauge is attached on the strain wall. A cable connected with an output end of the amplifier circuit board extends out of the base. An end cap is embedded in the blind hole, and an upper end face of the end cap is provided with a groove connecting through an edge of the end cap. A lower part of the base is provided with two holes. Two ports of the groove on the end cap are respectively abutted with the holes. The groove is abutted with the two holes, and a fluid passageway is formed in the base. When the fluid pressure transmitter is used, the two holes on the base are connected with a pipe tested fluid flows through. When the tested fluid flows through the fluid passageway, pressure of the fluid can be measured. In addition, through the two holes, the fluid passageway can be cleaned conveniently and thoroughly.
Description
Technical field
The utility model relates to pressure unit, specifically a kind of hydrodynamic pressure transmitter.
Background technology
Existingly a kind ofly for measuring the basic structure of hydrodynamic pressure transmitter, be: the top of a pedestal has cavity, bottom has blind hole, between the bottom surface of blind hole and the bottom surface of cavity, form strain wall, the strainometer that is provided with amplifier-chain plate in cavity and joins with it, strainometer docile is on strain wall, outside the cable pass-out pedestal that the output terminal of amplifier-chain plate is connected to.This kind of pressure unit in use, the pipeline that its blind hole and fluid pass through is connected, when thering is the fluid of certain pressure, enter in blind hole, the pressure-acting of fluid is on strain wall, by strain, take into account amplifier-chain plate and pressure signal can be transformed into electric signal output, can obtain fluid pressure value.The problem that above-mentioned existing this pressure unit in use exists is, when it is for measuring after 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 clean the liquid remaining in blind hole, what want to clean bothers, therefore, be not suitable for using on liquid phase tester.
Utility model content
The purpose of this utility model is to provide a kind of pressure unit, and this pressure unit is when conversion detected fluid, and easy to clean and easily cleaning are thoroughly.
For achieving the above object, the present invention adopts following scheme: fluid pressure transmitter, the top of one pedestal has cavity, the bottom of pedestal has blind hole, between the bottom surface of blind hole and the bottom surface of cavity, form strain wall, the strainometer that is provided with amplifier-chain plate in the cavity of pedestal and joins with it, strainometer is attached on strain wall, the cable pass-out that the output terminal of amplifier-chain plate is connected to is to pedestal, in blind hole, be embedded with a plug, on the upper surface of plug, have the groove that connects its edge, the bottom of pedestal has two through holes, on plug, the two-port of groove is docked with a through hole respectively.
From such scheme, groove docks with two through hole, in pedestal, formed a fluid passage, while using the hydrodynamic pressure transmitter that the utility model provides, the pipeline that two through hole on pedestal and detected fluid are passed through is connected, during fluid passage in detected fluid by pedestal, can record the pressure of fluid; In addition, by two through hole, can facilitate, convection cell passage cleans thoroughly.
The utility model is rational in infrastructure, reliable, easy to clean, thoroughly, and it is especially suitable uses on liquid phase tester.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model one embodiment;
