Abstract (en)
[origin: WO2020099045A1] Proposed is a particulate sensor (12) comprising: a measuring chamber (30) having at least one test-gas inlet opening (32) and at least one test gas outlet opening (34), both the entire inlet cross-section of the test-gas inlet opening (32) and the entire outlet cross-section of the test-gas outlet opening (34) being smaller than a flow cross-section of the measuring chamber (30) perpendicular to the through-flow of said measuring chamber (30); a corona-discharge electrode (38) and a counter-electrode (40); and a device used to generate an electrical field between the corona-discharge electrode (38) and the counter-electrode (40), said field running from the corona-discharge electrode (38) to the counter-electrode (40) and generating a corona discharge. The particulate sensor (12) is characterised in that, other than the test-gas inlet opening (32) and the test-gas outlet opening (34), the measuring chamber (30) has no additional opening allowing the inflow or outflow of gas.
