摘要： A calibration apparatus for calibrating a scattered-light measuring device that is embodied to measure a particle concentration in motor vehicle exhaust gases, comprises at least one scattering body that has a number of scattering centers having a defined size and a defined mutual spacing. The scattering centers are disposed in such a way that the scattering body, upon irradiation with light from a light source, delivers scattered light having an intensity and a distribution predetermined by the scattering body.

摘要： A device for measuring a particulate concentration in motor vehicle exhaust gases, has a measuring chamber, which is able to be filled up with a gas-particulate mixture that is to be measured, at least one light source and at least one light sensor. The light sensor detects light that has been scattered by particulates present in the gas-particulate mixture. An exhaust gas supply device is developed to supply exhaust gas, that is to be measured, to the measuring chamber. A null gas low in particulates is able to be supplied from a null gas source to the measuring chamber. A switching element, which is situated between the exhaust gas supply device and the measuring chamber, is suitable for admitting or forestalling the supply of exhaust gas into the measuring chamber on an optional basis.

摘要： A device for measuring the particle concentration in an aerosol using a flow tube includes a cavity in which there is a sleeve, the cavity branching off from the flow tube. The sleeve includes, at its end facing away from the flow tube, a collar. The collar encircles the periphery of the sleeve and is fastened at the periphery of the cavity. There is one or more inflow openings in the collar. At least one outflow opening is in an end of the sleeve, which end extends into the flow tube. A measuring chamber is also included in the cavity on the side of the sleeve facing away from the flow tube.

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