Diaphragm Pressure Gauges
Description
Diaphragm pressure gauge is composed of diaphragm separation device
and pressure gauge matched. It is widely used in petroleum,
chemical, medicine, foodstuff, and papermaking industries to measure
the pressure of liquid media with strong corrosion, high viscosity,
easy crystallization or solid granule.
Shock-proof pressure gauge is adopted as matched gauge head of
shock-proof diaphragm pressure gauge, which avoids the effect of
medium pulsation and environment shock and results in stable and
reliable indication and improvement of life expectancy of the gauge.
Type Naming
Example: YNMF-100 0-1MPa axial shock-proof spacer type
pressure gauge with front rim, 100 for diameter.
