Title: PARTICLE SENSOR WITH A PROTECTION ELEMENT AGAINST SOILING
Abstract:
The invention relates to a particle sensor (100) for detecting the amount of particles in a gas flow in an internal combustion engine. The particle sensor (100) comprises a housing (110) in which a measuring area (120) is arranged, an essentially cylindrical sensor electrode (130) which is at least partially arranged in the measuring area (120) and which extends over the second housing range (118) from the measuring area (120), and an electric, non-conductive protection element (160) which is placed on the sensor electrode (130) and is designed to at least partially prevent the gas flow in the second housing range (118) from flowing out from the measuring area (120).
