Quick Answer:
Short Answer
Calculate: (max width - min width) ÷ 2 + wander margin. Select next larger sensor size.
Calculate the sensor field of view needed: (1) Find total width change (max width - min width), (2) Divide by 2 (change per side), (3) Add wander delta (typically ±10-25mm safety margin), (4) Select the next larger sensor. For example, if running webs from 400-500mm with ±15mm wander: Total change = 100mm ÷ 2 = 50mm per side, plus 15mm wander = 65mm needed. Choose the ODC 96 (96mm window) as the ODC 48 would be too small.
