1 Overview

YP series diaphragm -type pressure gauge for measuring a variety of media for steel and copper and other metals do not corrode liquid, gas pressure and negative pressure; VPF Series corrosion diaphragm pressure gauge can be used to measure corrosive liquids, various media gas pressure and negative .

2, the structural principle

Structure: Diaphragm -type pressure gauge from the diaphragm parts, movement parts, components and casing connection pointer parts of four major components .

Principle: diaphragm pressure gauge is a diaphragm as a strong instrument of components, when measured media pressure to the diaphragm, the diaphragm produces a displacement, through the movement components, the pointer components of the work, so to be measured the pressure is clearly on the dial is indicated .
