Transmitter Promass 80 (remote version)
The Promass 80 transmitter (remote version) has a T6 temperature class rating when
installed in the EEx d housing for operation at ambient temperatures up to T
Gas explosion protection
Determine the temperature class dependent on the ambient temperature and the
medium temperature.
Dust explosion protection
Determine the maximum surface temperature dependent on the ambient temperature
and the medium temperature.
