Appendix A: Photocell Taping - Honeywell Vibrex 2000 User Manual

Appendix A: Photocell
Taping
This appendix helps the user determine how much retro-
reflective tape (tape width) to use with the Vibrex 2000 and
Vibrex 2000 Plus systems' photocell installations.
Tape Width Determination
The user may determine the optimum photocell tape width for
the subject aircraft in the following ways:

Mathematical formula

Simplified table

Numerical graph
Mathematical Formula
Use the following formula to calculate the minimum width of
retro- reflective tape necessary:
Express the answer in inches. Use the following values and units
with this equation:
  = 3.1416

Radius = Distance of the tape from the center of rotation in
inches

Rate = Rotational rate in Hertz (cycles per second)
