NON-INVASIVE GAS DETECTION

摘要

The present subject matter relates to a system for non-invasively measuring the oxygen content inside a metallic enclosure (100) is disclosed. A sensor module (110) positioned inside the metallic enclosure(100) senses the oxygen content inside the metallic enclosure (100), and transmits the sensed oxygen content information to a detector module (130) positioned outside the metallic enclosure (100), by means of vibration of the metallic enclosure (100). The detector module (130) picks up the vibrations and raises alarm in case the oxygen content inside the metallic enclosure is beyond predefined threshold level.
