Page 15: Width Measurement
Applications 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. -
Page 16: Device Configuration
Device configuration General information To configure the GS 754B forked photoelectric sensor, you require a PC with an RS 232 interface and a terminal program with the following setting. For this, use the corresponding KB-ODS 96-1500 cable (part no. 50082007). -
