Benefits

​Intuitive operation

Dräger developed the simple and structured operation concept of the Polytron 7000 in collaboration with its customers. The big graphic display shows status information with the help of pictograms and plain text and guides the user through calibration and configuration.

Communication interfaces

​If desired, a 4 to 20 mA signal, HART®, LON, PROFIBUS® or
FOUNDATION Fieldbus™, can take over the link between the Dräger Polytron
7000 and the control system. The modular design allows for the
subsequent retrofit onto one of the mentioned interfaces.

Robust enclosure

​The design of the compact, impact-resistant, fiber-glass
reinforced plastic enclosure is guarded against dust and splashing in
accordance with (IP66/67). The transmitter has been approved according
to the SIL 2 specification and it offers highest resistance to
electromagnetic interferences.

Relay module

​The Dräger Polytron 7000 can be equipped with a relay module.
It can thus be used as an independent gas detection system with two
concentration alarms and one interference alarm.Not to be used in
hazardous areas.

Intelligent sensors

The Dräger Polytron 7000 can measure 100 different gases. The
DrägerSensors that were specifically developed for all-year round,
permanent use in a stationary gas detection systems are known for their
long life time and the excellent measuring quality. The built-in sensor
data memory contains all the relevant information. This allows for the
use of pre-calibrated sensors so that the Dräger Polytron 7000 can be
used as a virtually maintenance free transmitter.

Software options

​With three different software dongles, different functions can
be built into the transmitter that adjust it to requirements specific
to its use.
With the sensor test dongle, the Dräger Polytron 7000 performs many
different patented sensor tests that ensure the reliability and
functionality of the sensor and the gas detection system. With the new
sensor diagnosis function (including the sensor test), operational
demands and the remaining sensor life time is estimated so that
maintenance and exchange schedules can be created. A data and event
saving option is integrated into the data dongle. This saves the
measured values and events such as alarms and warnings. The data can be
downloaded onto a PDA m515-Ex via an IR interface and evaluated on a PC
with the Dräger GasVision software packet. At the push of a button, a 15
minute concentration history is shown on the transmitter display.

Pump module

​An internal pump that sends the gas mixture to the sensor is a
further module option. The pump is an integral part of the Dräger
Polytron 7000. Not to be used in hazardous areas.
