DrägerSensor® IR
Contact usDrägerSensor® IR
Infrared Optical Gas Detector
- continuous monitoring of combustible gases and vapours
- compatible with: Polytron 8310, Polytron 5310, PIR 3000
- measuring range: 0 – 100 % LEL
Problem-free integration
With its Wheatstone bridge emulation, the Sensor IR outputs a mV signal, the same as the pellistor it replaces. The result is the control system sees the same signal input as before the Sensor IR was installed.
Naturally the Sensor IR can be operated with all Dräger control systems, more importantly it can also be connected to almost all installed systems from other manufacturers, without having to modify the wiring.
Smart and flexible
The Sensor IR offers a gas library with three gas categories: methane, propane and ethylene. Therefore, nearly all hydrocarbons are detectable. Temperature-compensatory linearising algorithms allow signal outputs 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 recognised and valued by gas detection users for a long time.
The Sensor IR now also offers these plus points for systems that have already been installed. Its long life time of over 15 years and long maintenance intervals mean that maintenance costs are significantly lower than for pellistors, make it a cost-effective, premium solution.
