The oil pressure gauge is do you use? Instrument answer: the main purpose of the oil filled pressure gauges are in order to reduce the pointer in relatively large variations in pressure buffer to zero, so that we can effectively ensure the sensitivity of pressure gauge. It mainly includes two kinds of glycerol and silicone oil. Glycerin: mainly seismic action; Silicone oil, and the earthquake effect, but the silicone oil than glycerol good low temperature resistance, if outdoor - Crystallization of the 20 ℃, glycerin, but silicone oil can make the instrument work normally. This kind of oil filled pressure gauge is also called seismic pressure gauge, good earthquake resistance. Seismic pressure gauge is suitable for the severe vibration environment, can tolerate the pulsation of the medium, the impact and sudden unloading, clear indication stability. Widely used in machinery, petroleum, chemical industry, metallurgy, mining, electricity and other departments, measurement of copper and copper alloy non-corrosive medium pressure.
