Pressure gauge why oil is in it? Below the instrument to solve for you: have the effect of shock pressure table have oil, with oil pressure gauge as the shock pressure gauge, oil charge is mainly 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. There is oil pressure gauge refers to the pressure gauge shell injection fluid, usually oil, liquid can have obvious impact on the earthquake cushion, so that it can reduce the pressure fluctuations or external vibration on the impact of the reading, through to the oil filled in the table, also parts of the machine lubrication effect and prolong the service life of the instrument at the same time. Oil filled pressure gauge of the commonly used oil has two kinds: glycerol: mainly is the 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.
