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:
DR�GER 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: 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:
Drager Polytron 5700
short response times
low sensitivity to dust or dirt deposits
on the optical surfaces and to insects
in the measuring cuvette
