What's the difference between the pressure gauge and the oil?
After oil is banned, it can be used to measure explosion, crystallization, solidification, liquid or gas that corrode copper and copper alloys
The difference is that the oil meter is forbidden to contact the oil medium when it is used, but the oil meter is not restricted to useThe oil ban is aimed at the contact medium of the pressure gaugePressure gauges usually do not have special instructions to work with the oil medium by default.But some pressure gauges, such as oxygen meter, ammonia meter, acetylene meter, etc., are not able to contact the oil medium for work, otherwise there will be explosion and other dangers. So it's called "oil prohibition meter".
No oil pressure gauge is mainly used for measuring the oxygen gas pressure refers to the table, because the oxygen and grease contact heating combustion and even the risk of explosion, so the oxygen pressure gauge at work or in the process of checking that absolute no oil (except glycerol). The name of the instrument on the dial of the oxygen pressure gauge is marked with a sky blue cross line and marked with the red "forbidden oil".
