Highlights
The catalytic DrägerSensors® are particularly insensitive to shock and offer excellent poisoning resistance. The high product quality and long-term stability ensure low operating costs. Fast response times provide reliable warnings of gas hazards.
Our own design
We develop the sensors with our own engineering knowledge. In this way, we can assure their quality and we know the measurements are accurate. This allows them to be fully utilised in combination with our full line of in-house developed Dräger gas de … More information
tectors.Shock resistance
The DrägerSensor CatEx SR (SR=shock resistant) is characterised by a special insensitivity to shock. A fall from a great height, which exceeds the standard requirements, has no effect on the sensor signal. The usual adjustment of the zero point and s … More information
ensitivity required after impact loading can be omitted, which saves time and effort.11 An adjustment is only necessary if, in case of high drop heights, the fresh air reading deviates from 0 after the impact.Durable and resistant against sensor poisons
Hydrogen sulphide and silicone are known catalytic poisons that may be present in environments where flammable gases can occur. Thanks to the imrpoved pellistor composition, the sensors are highly resistant to poisoning from these substances. This le … More information

Unknown gas hazards and higher hydrocarbons pose a particular challenge to the display sensitivity of catalytic sensors. The DrägerSensors CatEx are characterized by such a sensitivity. The detection of all hydrocarbons (from methane to nonane) has b … More information

Rapid response times
A rapid warning for flammable gases and vapours is vital. The CatEx sensors' fast response times minimise the timespan between danger and warning.
Fast calibration capability
With the DrägerSensor CatEx SR, fresh air calibration is possible after a maximum of only 60 seconds after switching-on the device. This saves valuable time and allows you to perform a fresh air calibration shortly before the shift, for example.
From the LEL to 100 vol. %
Our catalytic sensors are suitable for measurements from the lower explosion limit to 100 vol. %.
The X-am 8000 features the option to automatically switch the measurement ranges, making it easier to read off results when monitoring for high methane … More information
concentrations: if the CatEx sensor measures values above 100 % LEL, the display switches to the range of 0 to 100 vol. %.
