What causes fluctuations in the temperature gauge of the reactor?
Thread Content
In recent days, I’ve noticed that the thermometer on the reactor keeps fluctuating up and down. I checked the wiring and found no problems, and replacing the heat transfer oil didn’t help either. I really don’t know where the problem lies. There is toluene in the reactor, and the temperature is generally between 15 and 115. I need an expert’s advice on this.,
"Is the thermometer fluctuating?\" "Is the thermometer fluctuating?\" "“The thermometer is fluctuating,” really? . . With the spring blossoms in bloom, let me guess: it’s probably \"spring has arrived, and they’re in heat, ready to fall in love, right?\" Install another one and give it to a friend to try out. .
First, you need to look at the curve to see how it fluctuates; sharp rises and falls are usually due to issues such as wiring problems, temperature changes, safety barriers, or surges. If it rises or falls slowly, it is mostly a process issue. If the cause cannot be identified, the substitution method can be used; most thermometers come with a sleeve.
The thermometer isn’t behaving properly this season; it keeps showing erratic readings. We need to keep a close eye on it
The process has always been like this; it’s only recently that fluctuations have started to appear
Isn’t there a local bimetallic thermometer on site? If not, the remote transmitter can be temporarily removed and a local one installed so that the process engineers can observe the fluctuations on-site. If the fluctuations remain severe, it is not due to the instrument; the process team needs to investigate its own causes
Check the insulation of the wires, with respect to ground and the enclosure, etc. The description is too brief; it should include details such as the type of thermometer and the wiring configuration.
Is there a problem with the pipeline connecting the safety barrier and the card holder? Check it
