Recently, ASME updated its standard on thermowells from the previous standard, created in 1974, to ASME PTC 19.3TW – 2010. The new standard is designed to help overall reliability of temperature measurement.
“The PTC 19.3 Committee collected feedback from end-users and manufacturers and considered experimental results from the last 30 years to bring the standard into the 21st century. The result is a comprehensive set of calculations that offer the designer a complete evaluation of the thermowell design for a set of process and installation conditions," says Dirk Bauschke, engineering manager for Rosemount temperature sensors and thermowells, who represented Emerson on the ASME committee.
As a service, Emerson, Chanhassen, Minn., provides recommendations on thermowell design and installation best practices that comply with the new standard. For more information, visit www.rosemount.com/thermowellcalculations.
