2.5 Protection type for gas hazardous areas
In type of protection "Intrinsic Safety" the sensor meets the requirements of EN 60079-11. The
explosion protection is ensured by limitation of the current and voltage so that no ignitable
energy can occur.
The marking of the sensor is:
II 1G Ex ia IIC T6...T4 Ga
2.6 Temperature classes
The permissible temperature range depending on the temperature class of the sensor is:
The maximum permissible temperatures are valid under the following conditions:
•
The sensor is operated in its intended mounting position.
•
The sensor is not exposed to heat radiation (e.g. direct sunlight, adjoining hot parts).
•
Insulation does not obstruct the ventilation of the sensor.
