— For stationary, continuous monitoring of gas concentrations in ambient air, with built-in DrägerSensor
— Automatic configuration of transmitter to suit the built-in DrägerSensor.
— The measuring range may be selected, but it is dependent on the sensor installed.
— With 4 to 20 mA interface, LON communication, Foundation Fieldbus or PROFIBUS PA.
— For installation alternatively in Ex areas zone 0, 1, 2 or 22 corresponding to device category 1G, 2G, 3G, 3D or Class I,
Class II, Div. 1 & 2 hazardous area.
For further details, see the installation notes.

Maximum supply voltage: 30 V DC
As electrical equipment of the device class and category II 3D according to directive 94/9/EC, the transmitter Dräger Polytron
7000 can be installed and operated without safety barriers in the ATEX Zone 22 (dust), if the following notes concerning safe
use are taken into account.
1. The category II 3D is only valid for the accordingly marked Dräger Polytron 7000 transmitter.
2. According to EN 50281-1-2, the transmitter may not be installed in areas which are endangered by conductive, combustible
dusts.
3. The Transmitter and the accessories must be enclosed according to IP 6x rating. Especially the locking screw (2 mm Allen
screw) of the sensor bayonet ring tight enough to ensure that the bayonet ring is secured against unintended loosening.
4. The Dräger Polytron 7000 transmitter and the accessories have a maximum surface temperature of 65
The transmitter must be installed and maintained according to valid regulations (e.g. in European countries according to EN
50281-1-2).
5. The transmitter and the accessories may only be opened when off-circuit or outside the Ex area. This must always be observed
when replacing the sensor!
— Optionally compatible with HART
— Optionally available with pump module for the continuous supply of the gas/air mixture to be tested to the transmitter.
Caution: No explosion protection. Explosion hazard!
