Description
Diaphragm shock resistant pressure gauge y-60bfzml is used in petroleum, chemical industry, chemical fiber, dyeing and chemical industry, pharmaceutical industry, alkali food industry and other industries. Measure the pressure of corrosive, high viscosity, easy to crystallize, easy to solidify, high temperature liquid, gas or granular solid medium, and avoid the measuring medium directly entering the pressure instrument and prevent sediment accumulation and easy to clean
The pressure gauge is composed of pressure guiding system (including joint, spring tube, current limiting screw, etc.), gear transmission mechanism, number indicating device (pointer and dial) and shell (including case, cover, glass, etc.). The shell is airtight structure, which can effectively protect the internal parts from environmental impact and pollution invasion. For the instrument filled with liquid (usually silicone oil or glycerin) in the shell, it can resist the severe vibration of working environment and reduce the impact of medium pressure pulsation.
Corrosion resistance of diaphragm pressure gauge
The corrosion resistance of diaphragm pressure gauge can be ensured by proper selection of diaphragm, flange and sealing ring materials in contact with the measuring medium.
