Abstract
Exemplary embodiments of the present invention relate to methods and devices for monitoring the flow of particulate matter within an exhaust gas stream. In one exemplary embodiment, a particulate matter sensor for an exhaust system of an engine is provided. The particulate matter sensor includes a casing having an attachment feature for mounting the particulate matter sensor to the exhaust system. The particulate matter sensor also includes an insulator disposed within the casing. The particulate matter sensor further includes a sensing rod having a hollow portion extending between a first end and a second end of the sensing rod. The first end of the sensing rod is supported by the insulator and the second end of the sensing rod extending away from the insulator. The particulate matter sensor still further includes an electrical connector assembly engaging the first end of the sensing rod. The electrical connector assembly is configured to transmit a signal generated by the sensing rod.
