Diesel Particulate Filter (DPF)

Diesel particulate filters (DPF) are used to remove particulate matter from the exhaust gas of a diesel engine. The filter catches a large percentage of the particulate matter, but while doing so become obstructed requiring a cleaning process. A pressure sensor can be used to determine the level of obstruction in the filter and determine when a cleaning process should be initiated. SMI’s platinum based pressure sensors enable accurate and reliable direct measurement of the diesel exhaust gas, while surviving the harsh environment.
