DrägerSensor® IR

Upgrade to infrared technology "in the twinkling of an eye" - the DrägerSensor IR can replace catalytic ex-sensors (catalytic bead sensors, pellistors) without additional installation work.

Problem-free integration

​The DrägerSensor IR emulates a Wheatstone half-bridge. A bridge signal is sent in mV, and the sensor responds to the control system in the same way as a pellistor. For this reason, the DrägerSensor IR can be operated with all Dräger control systems without any problems. Furthermore, it can also be connected to almost all installed systems from other manufacturers, without having to modify the wiring.

Smart and flexible

The DrägerSensor IR offers a gas library with three gas categories: Methane, propane and ethylene. Therefore, nearly all hydrocarbons are detectable sufficiently well and sensitive. And finally, temperature-compensatory linearizing algorithms allow for signal output for individual substances. Through optional accessories – e.g. the process adapter or the duct mount set – a multitude of measuring tasks can be performed professionally.

Immune to pellistor poisons

Technological advantages in infrared technology (e.g. fail-safe operation or immunity against pellistor poisons) have been recognized and valued by the market for a long time.

The DrägerSensor IR now also offers these plus points for systems that have already been installed. Its long life time of over 15 years and the maintenance costs, which are usually significantly lower than for pellistors, make it a ost-effective, premium solution.
