ABSTRACT:
A method and a particle sensor for measuring particles, especially soot particles, in which the particles to be detected accumulate in a measuring region of the particle sensor. The particles located in the gas stream or the particles already accumulated in the measuring region are burned by a combustion device, the combustion being controlled via a control signal from a control unit, which is electrically connected to a measuring device, in such a way that the quantity of the particles adhering in the measuring region remains constant. The physical variable of the combustion device, which leads to the controlled combustion of the particles, is drawn upon as the signal amplitude of the particle sensor.
