| 摘要 |
A gas sensor processing apparatus (1) which includes voltage shift means (11, 19, S1071) for shifting a detection element voltage (VE) produced between electrodes (3P, 3N) of a detection element (3) from a pre-shift voltage (VE1) to a post-shift voltage (VE2); recovery means (11, 19, S1072) for returning the detection element voltage (VE) from the post-shift voltage (VE2) to the pre-shift voltage (VE1) after the end of a voltage shift period (TS) in which the detection element voltage (VE) is shifted by the voltage shift means; and deterioration index detection means (S106 - S107) for detecting a deterioration index (ID) representing the degree of deterioration of the detection element (3) on the basis of a voltage change in the recovery period (TK) in which the detection element voltage (VE) is recovered by the recovery means. |
