摘要： The present invention relates to a method for detecting particles and a particle sensor arrangement. More specifically, the present invention relates to a method and arrangement for detecting particles in a gas flow, e.g. from a diesel combustion engine. The method comprises the steps of; forcing a particle build up on a sensor element of a particle sensor arrangement by regulating the sensor element to a second temperature; wherein the second temperature is lower than a first temperature, the first temperature being the gas flow temperature. Additionally is the particle build up detected at the sensor element by means of a detector. The present invention provides for an accurate method and arrangement to detect and thereby measure particles present in a gas flow, e.g. from a combustion engine.
