    摘要: A gas sensor (8) includes a body (10) that is shaped to define a chamber (14). An electrolyte (34) is contained in the chamber (14) and three electrodes (26, 28 and 30) that are located on an electrode substrate (24) are disposed in contact with the electrolyte. The body (10) is electrically connected to the three electrodes. A cover (36) engages the body (10) to enclose the chamber (14). A resistor array (58a-58n) is located between the cover (36) and the electrode substrate (24). The resistors (58a-58n) are coated with a compound that emits a predetermined gas in response to temperature increase. To test the sensor (8) voltage is selectively applied to the resistor array (58a-58n) to introduce the gas to the gas diffusion path of the sensor (8).

    摘要: A gas sensor assembly having a first housing portion having a receptacle formed therein and a second housing portion in the form of a cover. A gas-sensing agent is disposed in the receptacle, and a working electrode, a counter electrode, and a reference electrode provided on a single electrode support sheet are disposed in fluid contact with the gas-sensing agent. The first housing portion is provided with three conductive housing portions which are in electrical contact with the three electrodes, and the cover maintains pressurized contact between the three conductive housing potions and the three corresponding electrodes. The gas sensor may be provided with two different types of leakage detectors to sense leakage of the gas-sensing agent from the sensor.
