Oil pressure inside have what pressure gauge?

Oil pressure inside have what pressure gauge? Below small make up for your answer! Oil filled pressure gauge is a kind of glycerine filling: mainly is the seismic action; Oil filled pressure gauge also charge is a kind of silicone oil, and the seismic 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. Pressure gauge is the main purpose of the oil filled in order to reduce 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. Oil filled pressure gauge is a sensitive element (by table Bourdon tubes, bellows, bellows) Elastic deformation, the pressure deformation by the transformation of movement in table to Pointers, cause the hands to display the pressure. Role is oil filled pressure gauge oil-filled shock, so there is vibration can be used, shake the situation a lot, such as injection molding machine, compressor, can use oil filled pressure gauge.
