5.1 Use of thermowells
CAUTION!
Damage due to incorrect handling
When using thermowells, please ensure that the stem does
not touch the bottom of the thermowell since, due to the
different expansion coefficients of the materials, the stem
may become buckled at the bottom of the thermowell.
▶
Use the correct insertion length (for the formula for the
calculation of the insertion length, l
thermowell data sheet).
