Today, a Rosemount pressure transmitter suddenly reached its maximum value
Thread Content
Today, a Rosemount pressure transmitter of mine suddenly reached its maximum value, which caused an interlock shutdown and led to significant losses. Has anyone encountered such a situation? Moreover, the pressure transmitter in question was just installed not long ago – it has only been in use for a few months.
Reply to 1# ksme200811: It’s quite normal. First, check the pressure transmitter; if there’s nothing wrong with the transmitter, then the increase in pressure is likely caused by other factors.
Well, remove the pressure transmitter and check it to see if there’s any issue with the transmitter
Break down the system for verification to determine whether it is a transmitter fault or a leak in the pressure guide tube on the negative pressure side.
It’s a single-flange pressure transmitter, and the actual pressure hasn’t increased. I’m posting this just to ask why Rosmont’s instruments would suddenly exhibit such behavior – why would this happen after less than half a year? Is it a quality issue?
Interference? ? ? ? ? ? ? ? ? ?
Are there no redundant points for getting off the train? That’s so strange.
There are many, many possible ways to analyze this
Some small factories in the country are focused on making money; they certainly don’t have the means to invest in such things – as long as they can produce products, that’s enough for them! In the hearts of most people in the country! Hehe
Reply to 5# ksme200811: First, check the data sheet of the flanged voltage transformer of the model you have chosen to see whether the temperature meets the requirements of the operating conditions. I have encountered situations where, under high-temperature conditions, the flange diaphragm box was damaged, resulting in linear variations. It is recommended to first check the data sheet, then remove it to inspect whether the diaphragm box is deformed and whether its elasticity is good, and finally conduct a pressure test to check its linearity. Next time you ask a question, please also specify the operating conditions. :time:
