Measurement and Testing
A Guide to the Selection and Application of Thermowells
Jun 23 2012
Author: Chris Chant on behalf of Okazaki
Chris Chant, of Okazaki Manufacturing Company (OMC), discusses the basic principles of a thermowell and provides a guide to their selection for use in oil, gas & petrochemicals applications.
Thermowells enable a temperature sensor to be located within a process flow, whilst providing a process seal and protecting the sensor from the process fluid. The primary function of a thermowell is to protect the temperature sensor from excessive pressures, fluid velocities and viscosities, corrosion and damage, ensuring a longer operating life and accurate temperature measurements. Maintenance is also simplified by allowing the sensor to be easily and quickly removed without having to drain the process pipe or tank.
