Diaphragm pressure gauge




1、Overview

   The diaphragm pressure gauge is composed of two parts: a diaphragm isolation device and a pressure gauge. Widely used in petroleum, chemical, pharmaceutical, food, paper and other industries to measure the pressure of liquid medium with strong corrosive, high viscosity, easy to crystallize and contain solid particles. The vibration-resistant diaphragm type pressure gauge effectively eliminates the influence of medium pulsation and environmental vibration due to the use of a durable pressure gauge, which makes the instrument indication stable and reliable, and also improves the service life of the instrument.
