Method and apparatus for detecting soot concentration in particulate trap |
| abstract |
A method of detecting the accumulation of particulate material collected on a filter medium formed of dielectric material in a chamber having the property of a microwave waveguide or transmission line comprises the steps of exciting the chamber with a microwave signal and monitoring the transmission loss of the signal through the line to sense the effective dielectric loss factor and thereby to provide an indication of the concentration or level of particulate material accumulated on the filter medium. |
