New Platform for NDIR Gas Sensors 

At the Sensor+Test show, which will be held in Nuremberg in May, smartGAS Mikrosensorik GmbH (Germany) will present a new generation of gas sensors. The new silarex platform utilises – like the previous smartMODUL – infrared absorption technology (NDIR) resulting in a high selectivity for the measured gas. Cross sensitivities with other gases are reduced to an absolute minimum. The engineers at smartGAS developed a new pressure compensation and an optimised temperature compensation for the new sensors. Accuracy and linearity are drastically increased, and at the same time the overall sensitivity is much better due to enhanced noise reduction. In the first step the new sensors will be available for the detection of SF6, CO, SO2, and ethylene. The silarex platform will enable the use of NDIR technology in various fields, which are not accessible with today’s standard sensors. Typical applications include monitoring in fruit ripening and storage (ethylene), measuring of emissions (CO, SO2), and monitoring of tracer gases (SF6).
