Definitions
- the gas flow (viewed in a sectional view along the longitudinal axis) is guided essentially snake-like through the particle sensor and the effective measuring surface or active measuring path provided by the hollow measuring section is efficiently and almost maximally utilized, which in turn leads to a larger and better evaluable measuring signal.
- the sensor electrode has a rod-shaped central section extending along the longitudinal axis, which is arranged within the second flow- conducting section .
- the central section can in turn at least partially lead to an enlargement of the active measuring surface or of the active measuring path of the sensor electrode.
- an outlet opening extending in the housing along the longitudinal axis is furthermore provided, through which the gas flow can flow out of the measuring area.
- the outlet opening is preferably located in the base section of the flow guidance element.
- Particle sensor of Fig. 1 shows
- the housing 110 further has a further, extending along the longitudinal axis 102 and the first housing portion 116 opposite housing portion 119 in which a contact receiving portion 122 is provided, in which at least partial electrical contacts (not shown) of Parti ⁇ kelsensors 100 can be accommodated , via which the particle sensor 100 can be connected to, for example, a control unit of a vehicle.
- the measuring section 132 is arranged around the second flow guiding section 144 such that a third flow path 108 is formed between a radial inner wall 133 of the measuring section 130 and a radial outer wall 145 of the second Strömungsleitabitess 144 such that the gas flow through the third flow path 104
- a fourth flow path 109 is formed in the hollow cylindrical second Strömungsleitabites 144 such that the gas flow flows through the fourth flow path 106 in the second direction, ie from the second Housing portion 118 in the direction of the first housing portion 116.
- the measuring portion 132, the guide portion at least a first flow 142 and the at least one second flow ⁇ guide section 144 have at least partially different diameters which permit engagement of these portions described herein.
