Example 3. Impulse sensor for second engine RPM control
Purpose: control of additional engine frequency
It is necessary to control the speed of the engine that drives the working body of additional attachments and
processes data in Omnicomm Online (calculate work time, downtime, etc.). For example, for the purpose of
control, it was not possible to locate the signal, the frequency of which is proportional to engine speed, and
an additional proximity sensor, triggered by crossing of marking on the engine shaft, was identi
fi
ed; based
on the symmetry on the engine shaft, four markings were secured (Figure 52).
