Particle sensor for an internal combustion engine

The invention relates to a particle sensor for detecting a particle quantity in a gas flow in an internal combustion engine. The particle sensor (100) has a housing (110), in which a measuring region(120) is arranged that extends along a longitudinal axis (102), a sensor electrode (130) which is arr...

Summary:The invention relates to a particle sensor for detecting a particle quantity in a gas flow in an internal combustion engine. The particle sensor (100) has a housing (110), in which a measuring region(120) is arranged that extends along a longitudinal axis (102), a sensor electrode (130) which is arranged in the measuring region (120) and which has an at least partly hollow measuring section (132)extending coaxially to the longitudinal axis (102), and a flow conducting element (140) which is arranged in the measuring region (120) and has at least one first at least partly hollow flow conducting section (142) that extends coaxially to the longitudinal axis (102) and at least one second at least partly hollow flow conducting section (144) that extends coaxially to the longitudinal axis (102) and is arranged within the first flow conducting section (142) with respect to the longitudinal axis (102). The measuring section (132), the first flow conducting section (142), and the second flowconducting section (144) ar
