Drager Polytron 8700


Quick and reliable detection of combustible gases and vapours in the ambient air: the microprocessor-based Polytron 8700 transmitter, which contains a new, innovative IR sensor with drift-free and resistant optics, can also be integrated into your digital fieldbus system, thus providing additional diagnostic functions.

SIMPLE INSTRUMENT MANAGEMENT THANKS TO DIGITAL COMMUNICATION

With its HART ability, the Drager Polytron 8700 allows remote access using the Drager PolySoft 8000 software for the quick and convenient evaluation of the instrument status. Integration in existing management systems (e.g. PactWare) is also possible using DTM. In addition, fieldbus systems such as Foundation Fieldbus or Profibus are supported by corresponding interfaces.

EFFICIENT, STABLE AND ROBUST – DRÄGER PIR 7000

With short response times and a high signal stability, the Drager PIR 7000 offers a high degree of safety – thanks to an extremely light-efficient optics with a 4-beam signal-stabilizing system. Another advantage is its low sensitivity to dust or dirt deposits on the optical surfaces and to insects in the measuring cuvette, while offering a drift-free output signal and longer maintenance intervals.

PROVEN – AND STILL GETTING BETTER: DRÄGER MEASUREMENT TECHNOLOGY

Drager has been developing and manufacturing sensors and gas detectors for industrial use for more than 40 years. And with each new device generation, we drive our measurement technology a bit further. With the Polytron 8700, you will definitely benefit from this experience and power of innovation. Its sensors are based on an open, double-compensated optical infrared system.

OPTIONAL: TWO MOUNTING SETS FOR EASY FLANGE-MOUNTING

The housing has four mounting holes. Two different mounting sets are available for installing the Polytron 8700: a duct-mount and a pipe-mount set. This means that the transmitter can be easily installed anywhere – e.g., on a smooth wall, a pipe or an exhaust duct.



OPTIONAL: THREE RELAYS FOR CONTROLLING EXTERNAL EQUIPMENT

On request, the Drager Polytron 8700 can be equipped 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. Audio alarms, signal lights, or similar devices can, thus, be controlled locally – without an additional cable between the transmitter and a central controller. The sensor signal can be evaluated using the 4 to 20 mA signal.

LIBRARY CONTAINING UP TO 100 GASES (TYPES 334 AND 340)

Each of the gases listed there can, for example, be cross-calibrated with vapours and preset gases, such as methane or propane. All calculations and linearisations are performed automatically.
