Thermowells are essential to protecting your thermometer or temperature sensor in your high-pressure or high-temperature applications. They can protect your investment and keep your measurements accurate, no matter how extreme the environment. One of the top questions we receive here at Ashcroft from those in the temperature measurement industry is how to properly fit a thermowell. What measurements are needed? What is a u-dimension and how does it factor in? Many factors are at play, and it can be easy to get the wrong size if you aren’t paying attention.

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.

The thermometer industry is vast with an endless array of temperature measuring instruments of all shapes and sizes. From the thermometer monitoring the temperature of a chemical plant to the one you use to see if your child has a fever, the quality and cost vary greatly.
