A pressure gauge with oil is an oil filled pressure gauge, also known as a seismic pressure gauge. It is a mechanical pointer type pressure gauge with filled liquid inside the gauge housing, or a mechanical pointer (or rotary dial) type pressure gauge with filled liquid and a damper inside the gauge housing. It is composed of a pressure guiding system (including joints, spring tubes, flow limiting screws, etc.), a gear transmission mechanism, a reading device (pointer and dial), and an outer shell (including the gauge housing, cover, gauge glass, etc.). The oil filled pressure gauge has good seismic resistance. Especially suitable for measuring fluid pressure in media with severe pulsation or instantaneous impact. The transmission indicator mechanism is located in viscous damping fluid, greatly weakening the impact of mechanical vibration in the environment where the instrument is located on its operation. It adopts an umbrella sealed structure and can work in harsh environments such as high humidity, dust, and water. It has the characteristic of preventing blockages and can be used for measuring high viscosity, easy crystallization, solidification media such as cement and mud.
Seismic pressure gauges are suitable for environments with severe vibrations, and can withstand the pulsation, impact, and sudden unloading of media. The instrument indications are stable and clear. Widely used in mechanical, petroleum, chemical, metallurgical, mining, power and other sectors to measure the pressure of non corrosive media on copper and copper alloys.
A pressure gauge without oil is a regular pressure gauge. Regular pressure gauges belong to the local indication type pressure gauge, which displays the pressure on site and does not have remote transmission display and adjustment functions. Ordinary pressure gauges are suitable for measuring the pressure and vacuum of liquids, gases, or vapors that are non explosive, non crystalline, non solidifying, and non corrosive to copper and copper alloys. In industrial process control and technical measurement processes, due to the high mechanical strength of the elastic sensitive components of general pressure gauges, as well as the characteristics of easy production, installation, and reading, general pressure gauges are becoming increasingly widely used.
