Catalytic flammable gas sensor Dräger Safety

Catalytic DrägerSensors

Catalytic DrägerSensors for the detection of flammable gases and vapors utilise Pellistors which are based on the catalytic effect. Different sensor versions will suit even the most demanding industrial applications.

The DrägerSensor Ex PR M (PR = poison resistant) contains pellistors, which in the presence of catalytic poisons have a longer lifetime than conventional sensors.

The DrägerSensor Ex HT M contains also PR-pellistors, but additionally is approved to be used at temperatures up to 150 °C.

The DrägerSensor Ex LC M contains PR-pellistors, which by their special encapsulation and electronic amplification are suitable to monitor very low gas concentrations. The measuring range is 0...10% LEL.
