What is the purpose of the liquid in the pressure gauge dial? Thank you :)
Gauges filled with liquid inside a casing (usually silicone oil or glycerin) can withstand severe vibrations in the operating environment and reduce the impact of pressure fluctuations in the medium.
It serves to absorb shocks and ensure the accuracy of measurements!
Shock absorption, lubrication, rust prevention~~~~~~~~~But not all watches have these features.
I noticed oil inside the pressure gauge before; I didn’t know what its purpose was, but I found out today! I’m here to learn*!
It mainly serves to absorb shocks; some instruments equipped with dampers can also serve this purpose.
I remember the first time I saw liquid inside the dial; I thought some material had leaked in, and I even reported it over the intercom. I guess everyone in the entire workshop knew about it: L
Take a look; those are all seismic pressure gauges
