Process Engineering Division – Instrumentation and Automation Section – Daily Question – Question from 2020-07-11: Discussion question: 175. How to check whether there is grease in the oxygen pressure gauge?
Use a syringe to inject pure warm water into the spring tube; after shaking, pour the water into a container filled with clean water. If there are no colored oil spots on the surface of the water, it can be assumed that there is no grease present
When calibrating the oxygen pressure indication value, first check whether there is any grease inside the gauge. The method is to first pour pure warm water into the spring tube, shake it, and then pour the water into a container filled with clean water; if there are no colored oil stains on the surface of the water, it can be assumed that there is no grease present.

Pour hot water in, then pour it out again to check for any oil floating on the surface of the hot water
