When using thermowells, they must be filled with a thermal contact

outer wall of the sensor and the inner wall of the thermowell. The
working temperature of the thermal compound is -40 ... +200 °C.

WARNING!
Before storing the instrument (following operation),
remove any residual media. This is of particular impor-
tance if the medium is hazardous to health, e.g. caustic,
toxic, carcinogenic, radioactive, etc.
The use of liquid damping is always recommended for
temperatures near the dew point (±1 °C around 0 °C).
WARNING!
Do not fill hot thermowells. There is a risk of the oil
spraying out!
