Method and device for measuring the load on an atmosphere of aerosols and dusts

摘要

A method for measuring the loading of an atmosphere with aerosols or dusts in a measuring chamber of a given width with a laser beam generating means (1) at a first end of a measuring section and a photoelectric measuring device (5) at a second end of the measuring section, wherein the laser beam in the direction of the width of the with aerosols or dust particles loaded measuring chamber is passed through the measuring segment, and wherein in the beam direction of the laser beam by a first photosensor (6) the absorption of the laser beam by the aerosols or dusts is detected, characterized in that, by means of an outside of the beam direction of the laser beam (2) arranged second photosensor (7) at the same time a by means of the aerosols or dusts, the bending of the laser beam is detected, and that from the ratio between the signals of the sensors is a load measure is formed, which the loading of the atmosphere with aerosols or dusts corresponds to.
