摘要： A sensor assembly to measure particulate matter is described. The sensor assembly includes a voltage source, a sensor electrode, a grounded assembly, an integration capacitor, and a current meter. The sensor electrode is coupled to the voltage source to receive a voltage. The sensor electrode is disposed within a directed and controlled exhaust flow within the sensor assembly to facilitate particle agglomeration into particulate matter structures at a surface of the sensor electrode. The grounded assembly is coupled to a ground reference and disposed at a distance from the sensor electrode. The integration capacitor is coupled to a negative side of the voltage source. The integration capacitor is configured to integrate in time current pulses from charge transfers from the sensor electrode of the particulate matter structures. The current meter is coupled to the voltage source to measure an integrated value of current supplied to the voltage source in response to charge transfers from the sensor electrode to the particulate matter structures in the exhaust flow.

摘要： A flow head for a gas sensor having a sensing element is provided. The flow head includes a body at least partially defining a cavity in thermal communication with the sensing element. The body includes an inlet port located within an annular surface of the body and an outlet port located within the annular surface of the body. The body also includes an inlet passage offset from and parallel to the cavity, wherein the inlet passage configures the inlet port and the cavity to be in fluid communication with one another. The body further includes an outlet passage offset from and parallel to the cavity, wherein the outlet passage configures the outlet port and the cavity to be in fluid communication with one another.
