Device for measuring operating parameters in a machine

摘要

Device has a primary detector (2) which detects the working parameters of a part (1) of working machine and generates an output signal that is supplied to an evaluation unit (6). A secondary detector (3) detects same working parameters as the primary detctor and generates another output signal that is also supplied to the evaluation unit. Both detectors generate output signal different from each other by a change of the working parameter.
