Mixing tank temperature, do I need a thermowell?
Hi! We have a carbon steel mixing tank with a vertical vessel and an agitator. Now, we need a temperature sensor to keep the mix at 25 degrees Celsius. Do I need a thermowell? Which sensor has a faster response, RTD or thermocouple?.
Expert’s answer: Do I need a thermowell? Which sensor has a faster response, RTD or thermocouple?
Absolutely, you need a thermowell! You need to keep your sensor safe and your mixer going, right? The thermowell will allow you to install and remove the sensor without stopping your process.
Now, resistance temperature detector (RTD) or thermocouple? Normally, thermocouples need more upkeep and calibration than RTDs. They’re usually less accurate and less constant than RTDs too. Below 600 degrees Celsius, RTDs show up more often than thermocouples. They also tend to have more repeatability and stability.
So it sounds like an RTD will suit you best. On the other hand, a thermocouple can also do the job. You pick whichever you prefer. Either way, I suggest you go digital. A digital setup will provide you more data on your process and device conditions so you can avoid unscheduled downtimes.

Expert’s answer: Surface or thermowell sensors? – I know RTDs and thermocouples normally go in thermowells, but I see a lot about surface sensors lately. I hear that surface sensors actually offer the same accuracy and easier installation. Could you share your opinion?
Expert’s answer: Temperature transmitter class T3! – I am trying to install a thermowell into my process to measure the temperature of the flue gas. All temperature transmitters are in compliance with temperature class T3 means they support up to 200 degree Celsius. The surface of the application is higher than 200 degrees Celsius, is that a problem to implement a temperature transmitter?
Expert’s answer: What to do if you experience an RTD failure? – If the RTD sensor broke, what will happen? I found the signal in the PLC display didn’t change after I disconnect the sensor, I am afraid if the sensor fail in someday and the interlock will not active.
