Oil filled pressure gauge on the tip of the filling oil plug to cut off?

Oil filled pressure gauge is also called the shock pressure gauge, the main characteristics of seismic pressure gauge is good earthquake resistance, on the impact of transient fluid pressure and medium have intense pulse pressure measurement has good applicability. 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. Oil filled pressure gauge oil charge is to prevent the silicone oil ( Glycerin) Oil leakage, pressure table is filled with silicone oil ( Glycerin) 。 Seismic pressure gauge is suitable for used in places that have requirements of vibration. Silicone oil is low temperature resistant effect, glycerin is seismic effect, can make the table more accurate measurement, prolong service life. Filling oil plug is sometimes also called safety plug, leak protection, such as high pressure inside the plug will pop up, it does not easily blown glass. The oil filled pressure gauge on the tip of the filling oil plug to cut off? Instrument answer: the pressure gauge is installed, before use should be oil filled plug stabbed or cut a small hole bottom, make it to the atmosphere otherwise it will affect the accuracy of measurement. Seismic pressure gauge filling oil plug is not cut off: high pressure gauge is no problem, you'd better cut it off and low pressure or poke a hole.
