Hi there,
I am currently trying to employ a thermowell into my process to measure the flue gas temperature which has the range of 490-521 degree Celsius. However, the specification requires all the instruments to be in compliance with temperature class T3 which is 200 degree Celsius. Noted that the process pipe that I am trying to insert the thermowell is insulated internally. Therefore, I am wondering is that any possibility that the heat within the flue gas will be transferred to thermowell and eventually to the connection head via conduction?
If yes, does it mean that the surface temperature of the thermowell connection head will be more than 200 degree Celsius and it is not in compliance with that temperature class anymore?
Thanks for all your time!
