Title: PARTICLE SENSOR WITH A DEFLECTION ELEMENT
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 region (120) is arranged, a sensor electrode (130) which is arranged in the measuring area (120), a flow guiding element (140) which is arranged in the measuring area (120) such that a first flow path (104) is formed between the housing (110) and the flow guiding element (140), and a second flow path (106) is formed between the sensor electrode (130) and the flow guiding element (140), and a deflection element (150) that is designed to deflect the gas flow through the first flow path (104) into the second flow path (106).
