Rosemount differential pressure transmitter diaphragm box
Thread Content
Could some expert please advise me on the reasons behind the damage to the diaphragm box?
It’s probably frozen or under overpressure
1. The poster did not provide information on the medium used for measurement, so it is impossible to determine whether there is an issue with the material in contact with the liquid. 2. It seems that the diaphragm has been damaged due to freezing; was it not checked after winter, and only regular inspections were carried out now that the problem was discovered? 3. Overvoltage was considered next, but it is generally not an issue, as differential pressure transmitters have very high voltage tolerance. 4. There is a possibility of negative pressure; the poster should check the process procedures themselves. The points mentioned above are for reference only.
It’s good if it breaks – when it breaks, something new can be used; the corpses can also be sold as scrap to get alcohol. . . Congratulations! Wishing you prosperity. . . . :The direct cause of P is oil leakage. . . As for why there is oil leakage, I have no idea. . . . .
It was probably frozen before; the voltage tolerance is generally fine
The medium used for measurement is low-pressure steam, and there are measures in place to isolate it; I really didn’t pay attention to it after winter, and it was only during a recent inspection that I noticed it
