When using a thermowell, it’s important to ensure that it will work in the application. Wake turbulence caused by your process could break the thermowell and damage your temperature equipment. How can you ensure your thermowell is adequate? Calculating thermowell wake frequency can help. In this article, I will explain what thermowell wake frequency is and how to calculate it.

I was recently involved in an industrial project for a client’s critical application that required RTDs and thermocouples. The buyer’s main concern seemed to be the cost, assuming that all temperature sensors probably cost the same. However, not all applications are the same, and not all temperature sensors are created equal, so prices can vary. The prices of RTDs and thermocouples are determined by a number of factors, including the applications for which they’re being used and the temperatures in which they’re working.
