摘要：A particulate matter sensor is provided for sensing particulate matter presentin exhaust gases in a conduit. The particulate matter sensor includes a sensing elementwith a sensing face which extends into the exhaust conduit and provides a signal indicativeof the amount of particulate matter detected in the exhaust conduit. An inner shield is
provided to surround the sensing face and includes an inner shield inlet for admittingexhaust gases therein to be sensed. An outer shield surrounds a portion of the innershield and defines an outer shield chamber extending axially beyond the inner shield. Theouter shield has an outer shield inlet passage to receive exhaust gasses from the conduit.Exhaust gases enter the inner shield from the outer shield chamber through the innershield inlet.
