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.
Claims7
Method for machine diagnosis and especially for transmission diagnosis by analysis of the machine or transmission oil, in particular for the detection of ferritic wear particles, characterized in that a reed contact (1) is used, whose output signal is a measure of the condition of the machine or transmission.
Method according to any of the preceding claims, characterized in that a permanent magnet or an electromagnet is used as the capturing magnet (3).
