DrägerSensor IR

provides high reliability and excellent
measuring performance, e.g. in terms of
fast response and long-term stability.
The temperature range is specified from
– 40 to + 65 °C, and, due to the heated
optics, the sensor can be operated in
humid environments from 0 to 100 %RH.
Advanced flexibility
The customer can choose from three
different target gases – methane, propane
and ethylene – all listed in one internal gas
library. Via magnetic wand the selected
target gas can be changed – as well
after beginning of operation in the field.
Individual linearisation curves offer
temperature-compensated readings.
The mounting orientation is completely
flexible and the DrägerSensor IR is
approved according to worldwide preferred
standards: ATEX, IECEx, UL and CSA.
Weather protection is secured by the
attached splash guard, included in delivery
and certified with IP 67.
A wide range of accessories including
calibration adapter, process adapter and
duct mount set meet the advanced
requirements for special applications.
Pellistor-like behaviour
Due to the implemented emulation of a
Wheatstone half-bridge, a mV signal is
sent to the controller module and it
responds in exactly the same manner as
today with a pellistor. For this reason not
only all control systems manufactured by
Dräger Safety but also components of
most other control unit brands are
supported.
With its 3-wire connection, the
DrägerSensor IR does not need additional
wiring to be run. Thus, cabling efforts are
reduced to zero. Already mounted junction
boxes can be further used because of
metric M25 as well as 3/4" NPT thread
available with the new sensor.
Fail safe and immune to poison
Technological preferences such as fail safe
operation and immunity to poison,
combined with a long lifetime of more than
15 years and significantly-reduced
maintenance costs underline the
advantages of the DrägerSensor IR.
Based on an outstanding product quality,
the DrägerSensor IR is equipped with a
robust stainless steel enclosure and
The new DrägerSensor IR offers a cost-efficient opportunity to benefit from
IR-technological advantages without additional installation costs. Pellistors or
catalytic bead sensors already installed into various industries can easily be replaced
by the innovative DrägerSensor IR – without any technical hurdles. Neither the
control system nor the electrical wiring need to be adapted.
DrägerSensor IR:
Infrared optical sensor for
detecting combustible gases
with half-bridge interface
(like a pellistor).
