A device using intentionally introduced centrifugal force to direct particles suspended in a liquid to peripherally arranged contact members and to detain them there through the static pressure caused by the peripherally moving liquid. The device separates the ferrous, magnetizable, from the nonferrous, not magnetizable, particles by providing a magnetic capturing unit having a diameter smaller than that of the aforementioned contact member arrangement, so that ferrous particles will be retained by magnetism and so indicated, while nonferrous ones will be detained by the radially more outwardly located contact members and indicated accordingly. Individual indications of, especially nonferrous particle accumulations, are provided for at least two particle magnitude ranges.
