Answer Posted / ashwin jain
when the RTD is loose, the RTD probe direct contact to
thermowell body so RTD giving the temp.(100 deg) but when
we tighten with thermowell there is sum gap or space
between thermowell body & probe,so temp down to 90 deg.
also check the OD of thermowell.
OD of thermowell > RTD
