Thermowell Calculation Summary Report
Revision: AACalculations are based on the process data provided by the customer. The system designer is responsible for ensuring the thermowell material is compatible with the process fluid including identification of stress
corrosion or embrittlement effects. These calculations are intended to be an aid in choosing thermowells for specific applications. Calculations conform to ASME PTC 19.3 TW-2010 and are not meant to be a
guarantee against failure. This report is only valid with respect to thermowells produced and supplied by Emerson Process Management in accordance with our exacting quality standards.
