摘要： A degradation diagnosis method for simply performing degradation diagnosis of a gas sensor such as a hydrogen sensor. The hydrogen sensor has a reference detector member and common detector member, with each detector member respectively constituted of a detector element and temperature compensating element that form a pair. Power is normally supplied to the common detector member, which performs concentration detection of the hydrogen gas. When performing degradation diagnosis of this common detector member, concentration detection is performed simultaneously by each detector member for the gas of the prescribed hydrogen concentration by supplying power to both the common detector member and reference detector member and comparing the output value of the common detector member and the output value of the reference detector member.

摘要： A control apparatus for a gas sensor with a built-in heater is provided which can prevent damage to, deterioration of, and reduction in accuracy of detection of, a gas sensor. When an ignition switch is turned ON, supply of electricity to a heater 27 starts, and when the temperature in the vicinity of a gas sensor 15 (gas temperature of gas detection chamber 24) Ts becomes greater than a predetermined temperature #Ti at start, or when a predetermined electricity supply time after start of supply of electricity to the heater 27 has elapsed, the gas sensor 15 is started. The flow of off-gas is started simultaneously with starting of the gas sensor 15, or after starting. When the ignition switch is turned OFF, the flow of off gas is stopped, and the supply of electric power to the gas sensor 15 is stopped. In a state where a temperature difference ΔT between the gas temperature Ts inside the gas detection chamber 24, and an upstream gas temperature Tg is maintained within a predetermined range, the supply of electricity to the heater 27 is stopped after a predetermined time has elapsed after operation of the gas sensor 15 is stopped.

摘要： A gas-sensing element configured to measure a concentration of a specific component of a gas is mounted to a first circuit board which includes a driving circuit configured to drive the gas-sensing element. A moisture-proof material is disposed over at least one side of the first circuit board disposed in a tubular gas-sensing element case fixed to a sensor case. A gas-sensing chamber is defined by the first circuit board and an inner tubular surface of the gas-sensing element case, and opens at an open end of the gas-sensing element case to receive the gas to be monitored. A second circuit board which includes a control circuit configured to control the gas-sensing element via the driving circuit is fixed to a sensor case, and disposed in a position separate from the gas-sensing chamber such that the second circuit board is kept out of contact with the gas to be monitored.
