Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a gas sensor capable of precisely detecting the concentration of a combustible gas in a gas to be measured when the oxygen concentration in the gas to be measure or the element temperature is fluctuated, and having excellent detection responsiveness characteristic to the combustible gas component. SOLUTION: In a gas sensor 1, the oxygen concentration of a gas to be measured is regulated to a prescribed level by the operation of an oxygen concentration regulating pump element 3 in a first treatment chamber 9. The resulting gas is introduced to a second treatment chamber 10, and the combustible gas component is combusted by the assistant of electrodes 16, 17 functioning as oxidation catalytic part. Since a combustible gas component concentration detecting element 5 changes the output current according to the oxygen quantity change when the oxygen quantity is changed by the combustion in the state where a fixed voltage is applied, the original concentration information of the combustible gas component in the gas to be measured can be obtained from the output current.  The oxygen necessary for the combustion of the combustible gas component in the second treatment chamber 10 is supplemented by the oxygen sucked by a measuring oxygen supplying pump element 6. Since the change of the combustible gas component concentration is directly reflected to the current information change of the element 5, excellent detection responsiveness can be provided.

A difference from the digital command value is evaluated and added to a digital value before one timing to obtain a control signal digital value Y, which is then converted by a D/A converter 27 into an analog control signal (c). Each rotation detecting digital value is added to a feed amt. detecting variable to be accumulated, and when it becomes larger than the prescribed value, the sign of the digital command value is reversed, thus completing the intermittent feed motion. A stable and excellent precision intermittently feed reproducing is attained, thus improving the performance for a particular reproducing.
