Emerson Process Management’s thermowell calculator is now based on the new standard created by the American Society of Mechanical Engineers (ASME) that establishes the practical design considerations for thermowell installations.
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
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.
