Abstract

A soot sensor for the detection of soot particles in an exhaust gas flow, having interdigitally engaged measurement electrodes applied on a substrate. An electrical resistance between the measurement electrodes is a measure of soot load of the exhaust gas flow. The measurement electrodes are divided into two regions, a first region in which no soot particles can be deposited and a second region where soot particles are deposited from the exhaust gas flow. The first region and the second region are exposed simultaneously to the other conditions prevailing in the exhaust gas flow.
