Drager Polytron 5700


Quick, reliable and cost-effective detection of combustible gases and vapors in ambient air: the microprocessor-based transmitter is the result of more than 40 years of experience in measurement technology and contains a new, innovative IR sensor with drift-free optics. These optics are extremely resistant against deposits and insects in the beam.

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 5700, you will definitely benefit from this experience and power of innovation. Its sensors are based on an open, double-compensated optical infrared system. This innovative design offers the following advantages:

  short response times
  low sensitivity to dust or dirt deposits on the optical surfaces and to insects in the measuring cuvette
  longer maintenance intervals
  drift-free output signal
  high signal stability thanks to an extremely light-efficient optics with a 4-beam signal-stabilizing system

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

Each of the gases listed there can, for example, be cross-calibrated with vapors and preset gases, such as methane or propane. All calculations and linearizations 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 5700: 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

Upon request, the Drager Polytron 5700 can be supplied 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.

QUICK AND EASY WIRING

The electronics and the bezel form a single unit. Simply pull them out of the housing. Then insert the three-wire cable into the terminals – either through the Ex-e cable gland or through the seal on the conduit. Finally plug the terminal block into the PCB.

FURTHER ADVANTAGES:

  Available as flameproof or increased safety version
  Aluminum 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 flashlight
  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
