Diaphragm pressure gauge is composed of a diaphragm isolator and a general-purpose pressure gauge, the spring tube is pumped into a vacuum through special equipment, and filled with liquid, and the diaphragm is sealed with a diaphragm, when the pressure of the measured medium acts on the diaphragm sheet, so that it is deformed, and the conduction of the working liquid filled inside the compression system makes the free end of the elastic element (spring tube) in the pressure instrument produce the corresponding elastic deformation shift, and then the measured pressure value is displayed according to the working principle of the pressure gauge that matches it.
Diaphragm pressure gauge is suitable for measuring the pressure of medium with strong corrosion, high temperature, high viscosity, easy crystallization, easy coagulation, and solid floating, as well as the occasion where it is necessary to avoid the measurement medium directly entering the general-purpose pressure gauge and prevent the accumulation of sediment. Diaphragm pressure gauge is mainly used for the pressure of flow fluid medium in the production process of petrochemical, alkali, chemical fiber, dyeing and chemical, pharmaceutical, food and cheese making and other industrial sectors.
