Benefits

Simple instrument management thanks to digital communication

With its HART® ability, the Dräger
Polytron 8700 allows remote access using the Dräger 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.

Proven – and still getting better: dräger measurement technology

Dräger 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: three relays for controlling external equipment

On request, the Dräger 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.

Further advantages

  • Easy and cost-effective: one-man calibration
  • Quick and easy wiring
  • Aluminium or 316 L stainless steel housing for the most extreme industrial conditions
  • Extremely user-friendly software thanks to a minimum number of menu items
  • Backlit display: easy to read, even in the dark and without a flash light
  • Traffic light status indicator
    (green = no danger, yellow = error, flashing red = gas alarm)
  • Beam block warning signal if the optics are heavily contaminated
  • Measuring ranges in the ppm, %LEL and Vol% range
  • Matrix display allows the flexible setting of measuring ranges and units
  • SIL 2 certified by the German TÜV Süd

  • Efficient, stable and robust – Dräger PIR 7000

    With short response times and a high
    signal stability, the Dräger 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.

    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.

    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.
