Dräger Polytron 5100 EC Fixed gas detector

Detection of toxic gases and vapours

The Dräger Polytron 5100 EC is a cost-effective explosion-proof transmitter for the detection of toxic gases or oxygen. It uses a high-performance plug-and-play electrochemical Dräger Sensor to detect a specific gas. A 2 or 3-wire with 4 to 20 mA output with relays make it compatible with most control systems.

Durable, intelligent and sensitive – the Dräger Sensor

  • With unique electrochemical Dräger Sensors, Polytron 5100 can detect over 100 toxic gases and oxygen.
  • These long-life sensors provide continuous detection even under the harshest conditions. Dräger Sensors offer the industry’s widest temperature range between -40°C to +65°C (-40°F to +150°F).
  • The built-in memory contains all the necessary calibration and configuration information.
  • The sensors are calibrated ready for immediate operation.
  • The sensor’s intrinsically safe connection dispenses with the need for a flame arrestor giving you a faster response time and higher sensitivity.

Same design, same operating principle

  • Polytron 5100 belongs to the Dräger Polytron 5000 series.
  • All transmitters in this series have the same design and user interface.

The remote sensor option does not require conduit

  • The optional remote sensor enclosure enables the sensor to be installed away from the transmitter.
  • This makes it easy to place the sensor close to a potential gas cloud in an inaccessible location while keeping the display at eye level.
  • Because the sensor is connected to the transmitter through an intrinsically safe port, you don’t need to run conduit to mount a remote sensor.
  • And to make things even easier, Dräger includes cabling up to 100 feet (30 meters) long.
  • The intrinsically safe connection also allows ‘hot swaps’ in a hazardous atmosphere without disconnecting power or declassifying the area.

Dräger Polytron 3000 Fixed gas detector

Toxic Gas Detection

The Dräger Polytron® 3000 is an intrinsically safe gas detector for the continuous monitoring of more than 60 toxic gases and oxygen in ambient air.

It is the part of a new generation of gas detectors developed on a modular platform. Communication to the central control system is done via a 4 to 20 mA signal.

Simple, quick installation

The Polytron 3000 consists of two components, the docking station, for mechanical and electrical installation, and the Polytron 3000 transmitter. The docking station can be mounted and wired in advance, guarded against rain and dust by a modular cover until time of commissioning. During commissioning, the Polytron 3000 is simply inserted into the docking station and secured with a quick lock mechanism. After inserting the sensor, the system is ready for operation.

Wide range of applications

With its exceptional electromagnetic compatibility and a variety of mounting options, the CE marked Polytron 3000 is suitable for many different areas of application ranging from chemical to the semiconductor industries.

Easy to operate and maintain

The operation and maintenance of the Polytron 3000 is easy. The tried and tested Dräger Sensor is equipped with an integrated data memory that contains all calibration information. This allows the Polytron 3000 to accept a pre-calibrated sensor, speeding up maintenance or sensor change. If preferred, the sensor can be field calibrated in the transmitter.

Explosion Protection

  • Approvals for worldwide use including, ATEX, IECEx, UL, CSA and temperature range from -40 to +65°C, Protection class (IP66/67).

Dräger Polytron 7000 Fixed Gas Detector

Detection of toxic gases and oxygen

The Dräger Polytron® 7000 is a gas detector that can satisfy many toxic and oxygen gas measurement applications on a single platform.

It meets the requirements of the compliance market as well as the high specification requirements of customized solutions.

Easy Operation

  • Dräger developed the simple and structured software menu of the Polytron 7000 in collaboration with its customers.
  • The big graphic display shows status information with the help of icons and plain text, and guides the user through calibration and configuration.

Communication Interfaces

The wide range of outputs, 4 to 20 mA, HART®, LON, PROFIBUS® or FOUNDATION Fieldbus™, enables the use of the Polytron 7000 on either a control system from the Dräger Regard family, or third party control systems. The modular design allows for the subsequent retrofit onto any of the mentioned interfaces.

Remote Sensor

With the Polytron 7000 remote sensor adaptor and lead it is possible to mount the sensor up to 30 meters from the polytron 7000 transmitter. This enables the user to read and operate the transmitter from a safe area, or detect toxic gasses and oxygen levels in difficult to reach areas, whilst still being able to view and configure the Polytron 7000 from a convenient location. A duct mount kit enables the remote sensor to be mounted direct in elevated pipe work.

Relay module

The Dräger Polytron 7000 can be equipped with a relay module. With two gas alarm relays, and one fault alarm relay, the transmitter can either be used as a stand alone gas detector with no need for a controller; or alarm devices can be activated locally saving costs in cabling to and from a controller. The analogue signal can still be transmitted back to a controller if desired. (Not suitable for use in hazardous areas)

Intelligent sensors

The Dräger Polytron 7000 can detect over 100 different gases. Dräger Sensors are specifically designed for the demands of 24 hours per day, 365 days per year operation. The large Dräger Sensor size gives them their renowned long life. The built-in sensor data memory containing all the relevant gas and calibration information, together with on board temperature and pressure compensation gives the Dräger Sensor its unsurpassed measurement performance. This also allows the Polytron 7000 to accept pre-calibrated sensors, with minimal operator intervention, the Dräger Polytron 7000 is a virtually maintenance free transmitter.

Software options

With three different software dongles, a range of functions are incorporated into the transmitter adjusting it to user or application specific requirements. 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 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 Gas Vision software or at the push of a button, a 15-minute concentration history is shown on the transmitter display.

Pump module

The inclusion of a pump module enables the Polytron 7000 to draw gas samples from difficult to reach areas, the gas sample is then passed across the Dräger Sensor for detection. The pump unit, like all accessories in the Polytron 7000 range is modular, and can be retrofitted into existing transmitters. (Not suitable for use in hazardous areas)
