Abstract
A particle counter that operates according to the blackout and/or light blockade method for counting foreign particles in a fluid stream, in particular in a hydraulic fluid stream, has a photoelectric barrier whose beam of light penetrates through a measurement channel through which a bypass substream of the fluid stream flows and has an electronic analyzer downstream from the receiver of the photoelectric barrier. To this end, such a particle counter includes a pressure regulating device acting on the fluid stream forces a predefined pressure difference which is independent of the flow properties of the main fluid stream onto the area situated between the inlet and outlet of the measurement channel. (), The particle counter includes a heating or cooling device for regulating the temperature of the substream flowing through the measurement channel at a predetermined temperature level.
