Description

Fast and stable – the DrägerSensor® Ex
The built-in DrägerSensor® Ex is based on the proven catalytic bead measuring principle. It has excellent longterm stability with outstanding poison resistance. And this is the reason for its durability. Due to the novel gas
inlet opening, the sensor responds to gas in only a few seconds. This allows you to react immediately with
countermeasures and prevent the development of a flammable atmosphere.

Easy device management via digital communication
The Dräger Polytron 8200 is equipped with digital interfaces allowing for quick and easy remote interrogation
of the transmitter’s state. Integration with existing asset management systems such as PACTware™ is possible
via DTM. In addition to the common HART® communication system, the fieldbus interfaces PROFIBUS® PA,
FOUNDATION fieldbus™ H1, and Modbus RTU are also available.

Same design, same operating principle
The Dräger Polytron 8200 belongs to the Polytron 8000 series. All transmitters in this series have the
same design and user interface. This allows for uniform operation with reduced training and maintenance
requirements. The large graphic backlit display shows status information clearly and in an easy to use format.
The measured gas concentration, selected gas type, and measuring unit are displayed during normal operation.
Colored LEDs (green, yellow and red) provide additional alarm and status information.
The Polytron 8200 is operated by means of a magnetic wand over contact surfaces.

Three relays for controlling external equipment
Upon request, the Dräger Polytron 8200 can also be supplied with three integrated relays. This enables you to
use it as an independent gas detection system with two arbitrarily adjustable concentration alarms and one fault
alarm. Audible alarms, signal lights or similar devices can thus be controlled locally without an additional cable
between the transmitter and central controller.

Safe, robust housing for every application
Polytron 8200 features a Class I, Div. 1 rated explosion proof enclosure made from aluminium or stainless
steel, making it suitable for a wide range of environmental conditions. A protection type “e” version includes
a convenient docking station which allows installation in hazardous atmospheres without running conduit
(where approved) and this also facilitates pre-assembly.

Make the impossible possible with the remote sensor
The remote sensor connection housing allows you to install the sensor separately from the transmitter. This
allows you to simply place the sensor closer to the gas cloud in hard-to-reach locations. The display remains
