摘要

The invention relates to a sensor for detecting particles in a gaseous stream, in particular soot particles in an exhaust gas stream. Said sensor comprises at least two measuring electrodes (7, 8), which are located on a substrate (6) consisting of an insulating material. The measuring electrodes (7,8) are at least partially covered by a retaining shell (13; 21).
