Description
Technical field
The present invention relates to pressure unit, specifically a kind of fluid pressure transmitter.
Background technology
Existing a kind of basic structure for measuring fluid pressure transmitter is: the top of a pedestal has cavity, bottom has blind hole, formed between the bottom surface of blind hole and the bottom surface of cavity and strain wall, the strainometer being provided with amplifier-chain plate in cavity and connecting with it, strainometer docile 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 the fluid with certain pressure enters in blind hole, the pressure of fluid acts on strain wall, take into account amplifier-chain plate by strain pressure signal to be transformed into electric signal and to export, can fluid pressure value be obtained.Above-mentioned existing this pressure unit in use Problems existing is, when its for measure certain liquid pressure after, having a small amount of fluid to be measured remains in blind hole, the pressure of another liquid is measured if be used further to, for not affecting the constituent analysis of another kind of liquid, needing the liquid to remaining in blind hole to clean, wanting comparatively thoroughly then comparatively bothering of cleaning, therefore, be not suitable for using on liquid phase tester.
Summary of the invention
The object of the present invention is to provide a kind of pressure unit, this pressure unit when converting detected fluid, easy to clean and easily cleaning is 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, formed between the bottom surface of blind hole and the bottom surface of cavity and strain wall, the strainometer being provided with amplifier-chain plate in the cavity of pedestal and connecting 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 outside pedestal, a plug is embedded with in blind hole, the upper surface of plug has the groove at its edge through, 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, a fluid passage is defined in pedestal, when using fluid pressure transmitter provided by the invention, pipeline two through hole on pedestal and detected fluid passed through is connected, when detected fluid passes through the fluid passage in pedestal, the pressure of fluid can be recorded; In addition, by two through hole, can facilitate, thoroughly convection cell passage clean.
The present invention is rational in infrastructure, reliable, easy to clean, thoroughly, during it is especially suitable for using on liquid phase tester.
