Product Description
Application
Diaphragm-Seal pressure gauges are widely used in petroleum, chemical, alkali-making, chemical fiber, pharmaceutical, food, textile and other technological processes. It con be used to measure the pressure of media with strong corrosion, high temperature, high viscosity, crystalline, easy to solidify and with solid floating matter, as well 05 to measure the pressure of some media that can not directly enter the general pressure gouge, that is not easy to clean the precipitated material and prevent its accumulation.These problems can be solved by adopting a diaphragm-seal pressure gouge, which composed of a diaphragm isolator and a general pressure gauge.
Theory
When the pressure P of the measuring medium acts on the diaphragm, the diaphragm deforms and squeezes the sealing liquid of the pressure measuring system, producing a pressure of P-△P. When the rigidity of the diaphragm is small enough,△P will also be small, and the pressure inside the pressure measuring system is close to the pressure of the measuring medium.Working Theory
