Thermowells are traditionally a circular cylinder installed into the piping to protect the temperature sensors from the flow. From an Emerson whitepaper, Thermowell Calculations: As a process fluid passes around the thermowell, low pressure vortices are created on the...

Resources for Thermowell Selection and Design
Measuring and controlling temperature can the most important parameter in many production processes. It's not only the temperature sensors that are important, but how they are protected by thermowells. Wikipedia has a good definition of what thermowells are:...
Online Calculation Tool for Thermowell Installations
Back in 1974, the ASME (founded as the American Society of Mechanical Engineers) published a performance technology standard for thermowell calculations as well as overall temperature measurement best practices, PTC 19.3. Based on decades of industry and research...
Velocity Collars are Not the Answer to Thermowell Resonance
A few weeks ago, I highlighted the issue of resonance and thermowells in a post, New Thermowell Calculations Help Avoid Damaging Resonance. Thermowells are the circular cylinder installed like a cantilever into process piping. The temperature sensor goes into the...
New Thermowell Calculations Help Avoid Damaging Resonance
Last week, I visited our Emerson division that makes the Rosemount brand family of instrumentation. One of the things I learned coming out of those meetings was a new release of thermowell design standards. For those not already familiar with a thermowell, it's...
