Abstract
PURPOSE:To detect humidity and reducing gas with high precision and high reliability by using a ceramic semiconductor element of P type metal oxide of specific composition. CONSTITUTION:The sensor element 1 is constituted by the ceramic semiconductor 2 of P type metal oxide, by electrodes 3 and 4 of RuO2 system, for instance, formed on both side surfaces of the semiconductor 2 and by leads 5a and 5b led out from the electrodes 3 and 4. The semiconductor 2 has a composition of (1-X)mgCr2O4- XtiO2. When the detected ambient temperature is 150 deg.C or less, the detection of humidity is performed with ionic conduction of the semiconductor 2, while in the range wherein the temperature of the semiconductor 2 is 200-600 deg.C the detection of reducing gas is conducted with electronic conduction.
