Abstract

A procedure for operating a collecting particle sensor, which is provided with measuring phases, during which particles that are contained in an off-gas stream accumulate on a measuring route, and a device for implementing this procedure are submitted. Protection phases are provided, during which at least one measure for diminishing the accumulation of particles on the measuring route is adopted. The measure according to this invention prevents a decrease of the sensitivity of the particle sensor over a long period of time.
