Abstract:
1. A method for at least approximately continuously measuring particles in a gas stream in a measuring region of a particle sensor, the method comprising: accumulating the particles to be detected in the measuring region of the particle sensor; at least one of burning the accumulated particles by a partial regeneration of the measuring region, and burning the particles still located in the gas stream by a combustion device; and controlling combustion of the particles by the combustion device via a control signal from a control unit, which is connected to a measuring device, so that a quantity of the particles adhering in the measuring region remains constant, wherein the particles are removed via the partial regeneration to maintain the constant quantity of particles, determining from this, a signal amplitude of the particle sensor and correlating the signal amplitude to the quantity of particles in the gas stream.
