The Difference Between the Pressure Gauge with oil and without oil

Is the pressure gauge good for refueling or not for refueling? A: They have their own characteristics. Both pressure gauges will now be shown to you.

An oil-filled pressure gauge is an oil-filled pressure gauge, also known as a shock-proof pressure gauge. A mechanical pointer pressure gauge filled with liquid in the box, and a mechanical pointer (or turntable) pressure gauge filled with liquid in the box and equipped with a damper. It consists of a pressure guiding system (including joints, spring tubes, current limiting screws, etc.), gear transmission mechanism, digital indicating device (pointer and dial) and housing (including housing, cover, glass, etc.). Oil-filled pressure gauges have good shock resistance. It is especially suitable for fluid pressure measurement with severe pulsation or instantaneous impact. Its transmission-indicating mechanism is viscous damping fluid, which greatly weakens the influence of mechanical vibration on its work. The utility model can work in harsh environments such as high humidity and dust and underwater. It can be used for the measurement of high-viscosity, easy-to-crystallize, and easy-to-solidify media such as cement and mud.

Anti-vibration pressure gauges are suitable for places with severe vibration. It can withstand medium pulsation, shock and sudden unloading. The instrument indication is stable and clear. It is widely used in machinery, petroleum, chemical, metallurgy, mining, electric power and other departments to measure the pressure of non-corrosive media such as copper and copper alloys.

An oil-free pressure gauge is a commonly used pressure gauge. Ordinary pressure gauges belong to local indicating pressure gauges, which do not have remote transmission, display and adjustment functions, and display pressure on the spot. Ordinary pressure gauges are suitable for measuring the pressure and vacuum of liquid, gas or steam, without explosion, crystallization, solidification and corrosion of copper and copper alloys. In the process of industrial process control and technical measurement, general-purpose pressure gauges are widely used because of their high mechanical strength and convenient production and installation.
