Oil is oil filled pressure gauge pressure gauges, also known as seismic pressure gauge, seismic pressure gauge is on the basis of ordinary pressure gauge, filled damping liquid and add institutions, intense vibration and reduce environmental medium pulse influence on instrument, seismic pressure gauge has good shock resistance, stable indicate clearly. What's the pressure gauge oil oil? The instrument to solve for you: the inside of the seismic pressure gauge oil has two kinds: glycerol, and silicone oil. Glycerin: mainly seismic effect. Silicone oil, and the earthquake effect, only the silicone oil than glycerol good low temperature resistance, if 20 degrees under outdoor 0 glycerin crystallization. Silicone oil can make the instrument work normally. Seismic pressure gauge is suitable for the severe vibration environment places, are widely used in machinery, petroleum, chemical, metallurgy, mining, electricity and other departments, measurement of copper and copper alloy non-corrosive medium pressure.
