Device for obtaining operating signals for a machine

摘要

A device for obtaining signals for the operation of, in particular, an internal combustion engine contains a number of rows of teeth (4, 5) of different mark-space ratios and/or speeds of rotation, which rotate in parallel planes. They are allocated, in a common housing (7) of a pulse generator (6), individual magnetic-field-dependent sensors, for example Hall sensors (9, 10) which are preferably located in magnetic field paths of a common permanent magnet (8) (Figure 1). <IMAGE>
