Abstract
A sensor unit () for detecting a gas is configured with a pressure-tight measuring channel (), with a gas inlet () for introducing the gas into the measuring channel, with a gas outlet () for removing the gas from the measuring channel, and with a pump unit () for evacuating the measuring channel. The measuring channel has a gas sensor () for detecting the gas and a heating unit () for heating the gas sensor. The sensor unit () is configured to be operated in a measuring mode and in a regeneration mode. The measuring channel () is evacuated and the gas sensor () is heated in the regeneration mode.
