The ASME PTC-19.3-2016 thermowell calculation is done on the basis of the equation: The wake frequency calculation is used in three cases:ĭetermination of the critical temperatureĭetermination of a critical length or structural length ![]() This means that the temperature range where the thermopile is working does not enter the calculations and therefore the internal temperatures and the temperature difference between internal and external temperature are not used. ![]() The calculation does not consider the thermal factor of the thermopile. The specification most commonly imposed on the mechanical tolerance of the thermowell is the allowable stress differential or error divided by the length of the thermowell. The goal is to meet the mechanical tolerance specification based on the calculated result. The calculated result can be compared to the ASME PTC-19.3-2016 standard. This usually involves taking readings of internal and external temperatures and sensors and calculating the frequency using application note PTC-19.3. Wake frequencies are developed by a person (often a thermopile engineer) to find the calculated estimate. Wake Frequency Calculation Software Free Downloadl
