protect the thermometer bulb from corrosive effects, pressure and high flow of process fluids; Allow interchangeability of the thermometer for calibration or replacement without disturbing the process. Thermal conduction between bulb and thermowell is assured by mineral oil, aluminium, copper or graphite powder.
