Patent ID: 11391194

Abstract:
A gas sensor control apparatus (300) including a control section (61) which executes a first receiving process (STEP 1) for receiving a first detection result output from a mixed-potential-type ammonia detection section (42) for detecting ammonia contained in a gas under measurement and corresponding to the concentration of ammonia, a second receiving process (STEP 1) for receiving a second detection result output from an oxygen detection section (2) for detecting oxygen contained in the gas under measurement and corresponding to the concentration of oxygen, a first concentration calculation process (STEP 3) for calculating a first ammonia concentration of the gas under measurement based on the first detection result and the second detection result, and a pressure correction process (STEP 6) for correcting the first ammonia concentration based on pressure information obtained from an external device (220), thereby obtaining a second ammonia concentration of the gas under measurement.
