Process pressure
The pressure values to which the actual thermowell can be subjected at the various temperatures and
maximum permitted flow velocity are illustrated by the figure below. Occasionally, the pressure
loading capacity of the process connection can be considerably lower. The maximum allowable
process pressure for a specific thermometer is derived from the lower pressure value of the
thermowell and process connection.
