Infrared flammable gas sensor
Upgrade from Catalytic bead to infrared technology with ease using the DrägerSensor IR. The Sensor IR can replace catalytic ex-sensors (pellistors) from the majority of manufacturers without replacing controllers, cables, junction boxes or control systems.
With its Wheatstone bridge emulation, the DrägerSensor 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 DrägerSensor 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.
