Each thermowell is an important component of any temperature measurement point. It is used to provide a pressure boundary between the process and temperature measurement.
Thermowells help to protect the environment and operating personnel by keeping aggressive media, high pressures, and flow rates contained within the process boundaries. This also allows for the temperature sensor to be removed or replaced during operation.

Calculation of ScrutonWell® Design Based on ASME PTC 19.3 TW-2016 (Static)
- Maximum permissible pressure load with original tip diameter
- Maximum permissible bending load taking into account modified stem dimensions
- The dynamic part of the wake frequency calculation is not required because of the damping of the oscillation by more than 90 %.
