Difference between the Pressure Gauge with glycerin and without glycerin?

Why the Pressure Gauge that has liquid inside is oil or what exactly?

That liquid is glycerin, and the Pressure Gauge must have a type with glycerin and a type without glycerin. Everything has its cause and effect.

A pressure gauge with glycerin is good or bad. What kind of work is it suitable for? How does it apply to work?

Glycerin is a type of viscous liquid that has no smell, color, properties that are soluble in alcohol and water. Benefits of Glycerin are when placed in a pressure gauge, its viscous nature absorbs vibrations and pressure surges that occur with the Pressure Gauge causing the movement of the mechanism to slow down, reduces friction resulting in less wear.

It also helps in the matter of lubrication of the mechanism for non-stutter operation thus extending the service life for a longer time as well.

Why not dial the case completely filled?

The case is filled up to 80 percent to 90 to provide sufficient space for expansion and to prevent the case from leaking. That is the reason the case is not filled completely. The readability is good and the gauge point does not undergo vibration and shows actual exerting pressure.

What kind of pressure gauge is it suitable for?

  • In a location point where there is vibration all the time or vibration for a certain period of time, such as on a machine that is working all the time.
  • A point where there is a severe change in the environment, such as from very hot to very cold.

Therefore, when compared to the Pressure Gauge without glycerin, the operation of the various mechanisms inside the pressure Gauge will cause wear and tear. And the lifespan is shorter than the one with glycerin, of course.
