Sect. 6.4.2 of IEC 1127-1 is taken into account with the stated permissible ambient temperatures on
the sensor of VEGAVIB 62 and 66.
If the sensors of VEGAVIB VB6*.C****Z**** are operated at temperatures higher than those speci
-
fied in the above table, please make sure through appropriate measures that there is no danger of
ignition from the hot surfaces. The max. permissible temperature on the electronics/housing should
not exceed the values specified in the above table. The application conditions when operating in the
absence of explosive mixtures can be found in the manufacturer information.
When the sensor of VEGAVIB 61, 63, 65 and 67 is operated in hazardous atmospheres of zone 0,
there is no danger of ignition if it is operated under non-atmoshperic pressures from -1 to 16 bar and
temperatures according to the temperature classes T6 … T1.

above table, please make sure through appropriate measures that there is no danger of ignition
from the hot surfaces. The maximum temperature on the electronics/housing should not exceed
the values specified in the above table. The permissible operating temperatures and pressures are
stated in the manufacturer information.
Permissible process pressure

For temperatures on the sensor according to the temperature classes T6 … T1, pressures under
atmospheric conditions of 0.8 to 1.1 bar are permissible.
