Abstract

A method for machine diagnosis and, in particular, for transmission diagnosis of a machine or motor vehicle. The measurement system comprises a capturing magnet (2), on the surface of which the ferritic wear particles (3) to be detected accumulate. A binary measurement signal is produced by a reed contact (1) arranged opposite the capturing magnet (2). This measurement gives an indication of the condition of the machine or transmission.
