Catalytic Ex Sensors
Dräger catalytic Ex sensors monitor explosive mixtures in X-am series portable gas detectors. They measure from the lower explosive limit (LEL); for methane, measurement up to 100 vol.% is possible. An improved pellistor design makes them highly resistant to silicone and H2S poisoning, giving long-term stability and low operating costs. The CatEx SR (Shock Resistant) keeps its signal after falls from great heights and allows a fresh-air calibration within 60 seconds of switch-on. The CatEx H2 100 is optimised for hydrogen applications and measures from a few ppm or %LEL up to 100 vol.%.
