Polytron 7000

The Dräger Polytron 7000 is a gas detector that can satisfy all Toxic and Oxygen gas measurement applications on a single platform. It meets the requirements of the compliance market as well as the specification requirements of customized solutions. Developed with an innovative modular design, there is now the flexibility to choose and purchase only the features that the application requires.

The software menu of the Dräger Polytron 7000 was designed in partnership with our customers making it simple and easy to use. The large graphical display uses icons and plain text to show the status of the instrument, and guides the user through calibration and configuration. Calibration has been made even easier with the auto-calibration function.
With the Dräger Polytron 7000 the communication to the central control system can be selected, 4 to 20 mA and/or HART fieldbus. HART enables a simultaneous 4 to 20 mA signal and digital communication via the same single twisted pair line. Alternatively, up to eight transmitters can be daisy chained for operation on a single twisted pair connection in full digital mode. A number of software dongles with different software functionality customize the transmitter to specific application needs.

Sensor self test function, required for SIL 2 (Safety Integrity Level according EN 61 508), continuously performs patented sensor tests to ensure reliability of the gas detection system. Sensor Diagnostic Function evaluates the 'health' of the sensor to give the customer a warning before the sensors end of life. Datalogger and eventlogger options are implemented in this dongle, which will also display a 15 minute concentration graph.

Two component concept

The Dräger two component concept of a Docking Station and a Dräger Polytron 7000 electronics saves time and money. The Docking Station can be pre-installed – mounting and wiring it into place separately – while protected by a rain and dust cover until commissioning. At commissioning, the Dräger Polytron 7000 electronics is fixed by quick-lock mechanism into the Docking Station, the sensor inserted - and the system is ready for operation.
The Dräger Polytron 7000 can be equipped with a relay module which makes it a stand alone device with two gas alarms and one fault relay. The relay module forms a part of transmitter, so there is no additional installation cost or wiring to be done.

An internal pump for sampling the gas mixture to the sensor is also a module option. The pump fits inside the Dräger Polytron 7000 with no additional needs for wiring and extra mounting space. In combination with the pump and/or the relay module the transmitter must not be used in hazardous areas.

The remote sensor is easy to install on the wall or, with a duct adapter onto ducts up to 30 m from the transmitter. The duct mount kit enables direct mounting of the Dräger Polytron 7000 onto ducts and pipes. The Dräger Polytron 7000 has worldwide approvals: UL, CSA, ATEX, SIL 2.
