More Information
Summary:A resistor-assembly (10) includes a substrate (12), a heater (18), a resistor-element (22), and conductive-leads (34). The substrate (12) is formed of a ceramic-material (14). The heater (18) heats the resistor-assembly (10). The resistor-element (22) is formed of an ion-conducting material (24) that overlies the substrate (12). The conductive-leads (34) are formed of a catalytic-metal (36) that are in communication with a gas (32) and in electrical contact with the resistor-element (22). The resistor-element (22) is characterized by a resistance-value (40) influenced by an oxygen-presence in the gas (32) when the resistor-element (22) is heated by the heater (18) such that a resistor-temperature (26) is greater than a temperature-threshold (30).
