摘要： A diagnostic method and system is described for diagnosing an operating condition of a conductive particulate matter sensor. The sensor has a substrate with electrical resistance that varies with temperature and two electrodes on the substrate adapted to collect particulate matter between the electrodes, thereby establishing an electrically conductive path through collected particulate matter between the electrodes that can be detected by measuring electrical resistance between the electrodes, Relect. The diagnosis is performed by heating the substrate in the area between the electrodes and detecting whether resistance varies with temperature as expected, and then cooling the substrate back down and detecting whether resistance varies with temperature as expected. If resistance varies as expected during both heating and cooling, then a validation is diagnosed that the sensor is in proper operating condition if resistance increases in a manner consistent with evaporation of condensate. If resistance does not vary as expected, then a failure condition is diagnosed.

摘要： A ceramic connector body for a high temperature electrical connector, such as those used in high temperature gas sensors, incorporates a pair of opposing ceramic body portions which are operative for pivoting engagement and to be fixed in a connector body retainer which also enables their pivoting, hinged movement. The pivoting engagement permits the ceramic body portions to hinge open to receive a gas sensor with a low insertion force and a hinge close to provide the desired contact force. The ceramic body portions are also operative to house conductive terminals which provide electrical contact for power and signal communication with a gas sensor.

摘要： A connector assembly for a planar sensing element of an exhaust gas sensor is shown, with a method for assembling. There is an opposed pair of ceramic clamshells which retain terminals, each terminal mates to corresponding contact pads of the planar sensing element. A spacer is positioned between clamshells and a seal. A retainer clip binds the ceramic clamshells. These components are contained within an upper shield, upon assembly. The spacer creates a hinge point between the clamshell devices, allowing insertion of the sensing element without abrasion or scraping of the contact pads against the terminals The retainer clip, with radially extending tabs, keeps the opposed pair of ceramic clamshells under compression upon the sensing element when assembled, due to an interference fit with the upper shield of the sensor.
