WebThermowells are used to protect your temperature measurement instruments from the elements, which means they are often exposed to extreme environments and temperatures. Protecting the thermowell can help keep your temperature instruments safe and your application running. WebThermowells are tubular fittings designed to protect temperature sensors used in industrial monitoring processes. Processes like these most often exist in the cosmetics, food processing, pharmaceutical petrochemical, and refining industries, along with all those others that deal in processing. Typically, they’re installed in piping systems.

The alternating vortices that occur as the media flows across the shank can create turbulence causing the thermowell to resonate or oscillate. This is referred to as vortex shedding or Von Karmen trail.

WebMay 28, 2024 · According to the thumb rule, the Thermowell should be inserted into 1/3 rd or 2/3 rd depth of the fluid stream. The insertion length of the temperature sensor should be lesser than 1-2ʺ of the total length of Thermowell. This means the Thermowell should be 1-2ʺ longer than the sensor probe but it should expose the temperature sensing area for ... WebThermowells are cylindrical pressure-tight fittings used to protect the temperature sensors which are inserted into a pipe or vessel in industrial applications.
