Gas detectors, whether of the single or multi-gas type, depend on individual sensors to measure for specific gases in the air. These sensors have unique ways of making these measurements. For instance oxygen and combustible sensors use completely different technologies to operate. What they do all share in common is that they are not 'fail safe'.
[email protected]New gas sensor platform on infrared basis (NDIR) smartGAS Mikrosensorik GmbH presented a new generation of gas sensors at Sensor+Test. The new silarex sensor platform works by the method of infrared absorption (NDIR), which leads amongst other things to extremely high selectivity. Cross-sensitivities to other gases are reduced to a minimum.
