Abstract:

The requirements and principles of using photoacoustic gas detection technique in fire detection areaare discussed and an unusual photoacoustic gas detection system is presented.Common photoacoustic gas detection systems in laboratories are not suitable for fire warning becauseThese limitations can be solved with a different system design in which an enclosed photoacoustic cellThus CO selection in the absorption path is achieved by enclosed CO itself in the cell, and the photoacoustic
