Dräger Polytron® 7000

The Dräger Polytron® 7000 gas detector can satisfy all toxic gas and oxygen measurement applications on a single platform. It meets compliance requirements, as well as the high specification requirements of customized solutions.

Toxic Gases and Oxygen Detector

  • ​Sensor: Electrochemical Sensor
  • Installation: Intrinsic Safety
  • Interface: 4-20 mA, Bus, HART ®
  • IP class: 66/67 and SIL2
  • Special: Display

Intuitive operation

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

Intelligent sensors

The Dräger Polytron 7000 can measure 100 different gases. The DrägerSensors that were specifically developed for year-round, permanent use in a stationary gas detection systems are known for their long life 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.

Communication interfaces

The Polytron 4-20 mA signal can communicate with the control system using HART®, LON, PROFIBUS® or FOUNDATION Fieldbus, and 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.

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 via an IR interface and evaluated on a PC with the Dräger Polysoft software packet. At the push of a button, a 15 minute concentration history is shown on the transmitter display.

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 SIL2 specification and it offers highest resistance to electromagnetic interferences.

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.

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.
