If the permanent magnet of one coil
is closer than the other, the effective
coil length and thereby the
inductivity increases.
• Long primary coil =
higher inductivity =
high voltage
• Short primary coil =
lower inductivity =
low voltage
Starting from the mid point of the coil
system, the phase position of the
voltage between S1 and S2 changes
depending upon the direction of
movement of the permanent magnet.
The signal from the secondary coils is
fed back to the J556 controller.
There, the phase position with
respect to the primary coil and the
amplitude (voltage) are evaluated.
The evaluation electronics of the
control unit J556 convert the results
into a linear DC voltage signal
corresponding to the piston position.
The path signal generated by the
control unit J556 is transmitted to the
additional shift stage control unit
J554.
