MICROWAVE SENSING FOR DETERMINATION OF LOADING OF FILTERS |
摘要 |
<p>Method for determining loading of a filter. The filter has a first dielectric constant. The filter becomes loaded with contaminant material that has a second dielectric constant. The filter, such as a diesel particulate filter, is contained within a metallic enclosure forming a microwave cavity. The method includes establishing microwave energy in the cavity and monitoring changes in the cavity microwave response, the changes being related to filter loading.</p> |
