Gas Detector System for Industrial Use
Early detection of hazardous or flammable gasses/volatiles reduces the potential risks to personnel, such as development of respiratory problems. A simple robust resistive sensor device is presented with a sensing film of poly (styreneco-maleic acid) containing carbon nanotubes as the conductive medium. The response of the sensor was assessed with several volatile solvents and an industrial printer ink. All vapours were detected by increased resistance of the sensor film, and the ink vapour elicited the largest response. A warning system for volatile solvents could be based on this sensor design for use in industrial environments.
