Skin Temperature Estimation (Part 1)

Background

It's often necessary to determine a process temperature at a location where there is no thermowell. Skin or surface temperature thermocouples are a cheaper alternative to ...

{T_f}={T_m}+{c}({T_m}-{T_a})     (1)

where,

T_f is the fluid temperature
T_m is the measured skin temperature
T_a is the ambient temperature
c is the temperature correction factor (nominally, 0.06)
