Abstract (en)
[origin: WO2006008253A1] The invention relates to a gas sensor comprising a pump chamber (11) which is connected to a getter pump (30) by means of a throttle channel (20). The detection chamber (11) is closed by a wall (12, 13) that is selectively permeable only to hydrogen. The getter pump (30) sucks hydrogen out of the detection chamber (11). Hydrogen is detected by a highly sensitive pressure sensor (14) when it is diffused into the pump chamber (11) through the wall (12, 13). Said gas sensor has a simple structure and does not require a mass spectrometer.
