摘要：A measuring unit for measuring a particulate concentration in exhaust gasesusing scattered light includes a measuring chamber, at least one light source and at leastone light sensor, the measuring chamber being situated in the optical path of the lightsource; and the light sensor records the light scattered by the particulates in themeasuring chamber. To detect the intensity of light beam that is relevant for a preciseparticulate measurement, a monitoring device is provided to detect the intensity of thelight beam with the aid of a scattered radiation. The intensity of the light beam isrecorded using a monitoring measurement, by ascertaining a scattered radiation andcomparing it to a specified reference value for the scattered radiation. With the aid of thecomparison, the intensity of the light source is regulated correspondingly and/or themeasuring result of the particulate measurement is correspondingly corrected.
