What's the seismic pressure gauge

Seismic pressure gauge is the case with filling liquid mechanical pressure gauge pointer type, or in case there are pouring liquid and mechanical pointer with damper ( Or rotary dial) Pressure gauge, by conducting pressure system ( Including joint, spring pipe, current limiting screw, etc. ) , gear transmission mechanism, several devices ( Pointer and dial) And the shell ( Include atlas, table covers, table glass, etc. ) . The main characteristics of seismic pressure gauge is good shock resistance, fluid pressure and the medium of instantaneous impact intense pulse pressure measurement has good applicability. What's seismic pressure gauge? Seismic pressure gauge is mainly glycerin and silicone oil. Liquid to earthquake has obvious buffering effect. 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. Seismic pressure gauge is also known as seismic or oil filled pressure gauge pressure gauges, in machinery, petroleum, chemical, mining, power and other industrial use is to reduce the pointer in relatively large variations in pressure buffer to zero, so that we can effectively ensure the sensitivity of pressure gauge. Seismic pressure, long service life, got everyone's consistent high praise, is the alternative products of ordinary pressure gauge,
