Apparatus for sensing particulates in a gas flow stream |
摘要 |
A particulate sensor for sensing the presence of particulates in a gas flow stream is disclosed. The particulate sensor includes a housing having a flow divider to provide a first flow path and a second flow path. A heater is disposed and configured to provide uniform heating of the two flow paths. A first temperature sensor is disposed in the first flow path downstream of the heater. A second temperature sensor is disposed in the second flow path downstream of the heater. A fine filter is disposed within the second flow path and is configured to trap carbonaceous particulates.
