Width measurement
To measure the width of strip material, two GS 754B CCD forked photoelectric sensors can
be used mutually opposed from one another.
Figure 5.5:
Width measurement
Each forked photoelectric sensor relays an edge position which can be extrapolated to the
total width when the distance of the sensors vis-à-vis one another is known in the control.
In conjunction with this, time synchronization of the measurement data is ensured via PIN 2
as a trigger input. If the control generates a LOW -> HIGH signal change at the trigger inputs,
then both forked photoelectric sensors simultaneously each start an output cycle.
