Abstract
A device for ascertaining a particle concentration in an exhaust gas flow of a combustion device, particularly a diesel combustion device, is provided, which device ascertains very small particle concentrations in the exhaust gas of combustion devices, accompanied by high time resolution. At least one measuring unit is provided for measuring a concentration of an oxidizing agent in the exhaust gas flow, having at least one measuring element sensitive to the oxidizing agent.
