Based on calculations in accordance with ASME PTC 19.3 TW-2016
ASME PTC 19.3 TW-2016, the U.S. standard for evaluating the mechanical design of a thermowell used in a broad range of
applications, was updated in 2016 to include a greater number of thermowell and process variables. Sometimes referred to
as "Wake Frequency Calculation", the revision incorporates new elements for evaluating thermowell constructions
that will reduce the chance of vibration and stress damage to the vessel, as well as avoid vibration damage to the
temperature sensor it protects.
Please input data regarding your thermowell dimensions, thermowell properties and material/media/process properties in
the designated spaces below. We will review the data, process the calculations and contact you with the results. Feel
free to contact one of our Product Engineers to go through the process calculations.*
