Intended use
2.3.1
Purpose of the device
The device is a stationary oxygen measuring device and serves continuous measurement
of oxygen as emission and process monitoring in the industrial sector. The device
measures continuously directly in the gas duct (in-situ).
2.3.2
Operation in potentially explosive atmospheres
●
The ZIRKOR200 Ex-D measuring probe corresponds to the ATEX category (according to
ATEX 2014/34/EU):
II 2D Ex tb IIIC T133 °C/T141 °C Db
●
The ZIRKOR200 Ex-D measuring probe fulfills the following IECEx qualification:
Ex tb IIIC T133 °C/T141 °C Db
CAUTION:
Danger of explosion through incorrect or missing grounding
Incorrectly connected potential equalization can generate charges that can lead to
explosions in an Ex-atmosphere.
▸
Connect potential equalization to all points provided on the device components.
▸
Ensure the potential equalization is connected during all work on the device
described in these Operating Instructions.
▸
Ensure there is a ground connection via the power supply.
▸
Regularly check the grounding connections for correctness.
