Process for calibrating a gas sensor and for the subsequent use of the calibrated gas sensor

A process for operating a gas sensor (10), which process includes a calibration of the gas sensor (10). A test gas (16) is drawn in via a pump (12) coupled with the gas sensor (10), whereby the test gas (16) is supplied to the gas sensor (10). Different volume flows are generated by the pump (12) an...

Zusammenfassung:A process for operating a gas sensor (10), which process includes a calibration of the gas sensor (10). A test gas (16) is drawn in via a pump (12) coupled with the gas sensor (10), whereby the test gas (16) is supplied to the gas sensor (10). Different volume flows are generated by the pump (12) and respective volume flow-dependent measured values (26) are detected by the pump (12). The volume flow-dependent measured values (26) are recorded together with the respective volume flow. A sensor control unit and a computer program functioning as a control program (48) are provided to implement the process.
