II 2G Ex h IIC T4 Gb
II 2D Ex h IIIC T95°C Db
Explosive areas Zone 1 and 2, and 21 and 22, risk from gases and dry dust.
Allowed temperatures:
• The maximum surface temperature 95 °C was determined under the follow-
ing conditions without dust accumulation and safety factor.
• Allowed ambient temperature: -20°C to +60°C.
• Allowed medium temperature in the differential measurement unit < 85°C.
WARNING
Compression heat
With gaseous mediums, the instrument temperature can increase due to com-
pression heat. In such cases, the pressure change speed must be limited or re-
duced to the allow measuring substance temperature.
NOTICE! For a differential pressure change between 10% and 90% of the
measuring range and a pulse frequency < 0.06 Hz, the temperature in-
crease is <10K.
To avoid additional heating, the instruments may not be exposed to direct sun-
light during operation!
The standards EN60079-0, EN 60079-31, EN ISO 80079-36 and EN ISO
80079-37 apply for the non-electrical part of the devices in terms of explosion
protection. The applicable requirements of these standards are satisfied.
The documents for the mechanical part were filed with notified office NB0044
(TÜV-Nord-Cert) under the file number 8000389448.
