Thermowells are cylindrical-shaped casings found in any industrial environment where RTDs and thermocouples are integrated to measure changes in temperature. A staple of protection in the harsh environments of industries such as Power Generation, thermowells are made of a variety of metals and alloys designed to address specific environmental conditions. Over time, temperature sensing devices experience extreme forces—such as pressure, heat and/or corrosion—that can create additional issues that will challenge the optimal operation of equipment. Therefore, it takes knowledge and expertise to determine the best configuration of a thermowell to ensure the proper measurement of temperature variables.

One of the core challenges for thermowells is the increase in thermal response for an RTD or other temperature measurement device. The design of the thermowell often defines the discrepancy between the actual change in temperature and the reaction to that change in industrial processes. This can cause a range of issues for an industrial operation, which depends on the timely measurement of a change that can trigger an action in the system. Any slowdown in the response can result in a catastrophic event—mainly because by the time the temperature change is recorded, it may already be too late as temperatures may exceed well beyond its physical tolerances.

It should be noted that an inherent benefit of thermowells that may be easily overlooked is the fact that they allow for the inspection, calibration or maintenance of the temperature measurement device, without the need to stop their operation. This means that the equipment can be monitored effectively with ease and without an invasive maintenance effort. In a time when equipment operators want to ensure maximum availability, a thermowell is a necessary element of an industrial temperature measurement strategy—regardless of how simple or complex the system may be.

Temp-Pro works with customers to ensure the proper configuration that matches the expectation or need associated with response times in RTDs or thermocouples. This includes the consideration of whether to integrate a thermowell or the use of one with a thick or think wall for the fitting. Our experience in the design and customization of temperature measurement solutions plays a major role in the performance and longevity of an RTD, taking into account process parameters and the specific response time goals for a particular system. This approach allows us to effectively determine the optimal solution and thermowell configuration, which can ultimately ensure your operation’s success.
