I have installed a RTD whose length is 2250mm(RTD stem length), but it's upper 200 -250mm is out of the reactor, and this upper 200mm stem is surrounded by atmospheric temp. And the lower portion i.e. 2000mm is in contact with the measuring fluid, then does the final measuring temp. Gonna change as the upper 200mm RTD stem is out of reactor?
