Transmitter Prosonic Flow 93 P**-************
The Prosonic Flow 93 transmitter has a T6 temperature class rating when installed in the
PROline EEx d housing for operation at ambient temperatures up to T
The maximum ambient temperature range is –20...+60 °C.
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.
