Abstract (en)
[origin: WO2015104221A1] The invention relates to a sensor unit (10) for detecting a gas. In order to provide an improved sensor unit (10), the sensor unit according to one aspect of the invention is designed with: a pressure-tight measuring channel (11), a gas inlet (12) for introducing the gas into the measuring channel, a gas outlet (13) for discharging the gas from the measuring channel, and a pump unit (14) for evacuating the measuring channel, wherein the measuring channel has a gas sensor (15) for detecting the gas and a heating unit (16) for heating the gas sensor, and wherein the sensor unit (10) is designed to be operated in a measuring mode and a regeneration mode, wherein in the regeneration mode the measuring channel (11) is evacuated and the gas sensor (15) is heated.
