Is the pressure gauge good with or without oil? Answer: They each have their own characteristics, here to take you to understand the two pressure gauges.
Pressure gauges with oil are oil-filled pressure gauges, also known as shock-proof pressure gauges, which are mechanical pointer pressure gauges with filled liquid in the case, or mechanical pointer (or rotary dial) pressure gauges with dampers in the case with filled liquid. It is composed of pressure guide system (including joint, spring tube, current limiting screw, etc.), gear transmission mechanism, indicator device (pointer and dial) and shell (including case, cover, glass, etc.). Oil-filled pressure gauge has good shock resistance. It is especially suitable for the measurement of fluid pressure where the medium has violent pulsation or instantaneous impact. The transmission indicating mechanism is in viscous damping fluid, which greatly weakens the influence of mechanical vibration in the environment of the instrument on its work. It adopts umbrella-sealed structure and can work in harsh environment such as high humidity, dust and water. It has the characteristics of blocking, can be used for the measurement of high viscosity, easy crystallization, solidification such as cement, mud and other media.
The shock-proof pressure gauge is suitable for the place of severe vibration in the environment, can withstand the pulsation, impact and sudden unloading of the medium, and the instrument indication is stable and clear. It is widely used in machinery, petroleum, chemical industry, metallurgy, mining, electric power and other departments to measure the pressure of non-corrosive media on copper and copper alloys.
Pressure gauge without oil is the ordinary pressure gauge, the ordinary pressure gauge belongs to the local indication type pressure gauge, the local display of pressure, without remote transmission display, adjustment function. Ordinary pressure gauges are suitable for measuring the pressure and vacuum of liquids, gases or vapors that do not explode
