Guidelines for Excess Gain Values Excess Gain
Given the range from the above chart, excess gain can be calculated for any distance
by using the inverse square law. For example, the excess gain for a 30' range MINI-
SCREEN system at a 10' separation, using two corner mirrors, is calculated as
follows:
E.G. = (25.5') 2 = 6.5 E.G. = (1x) (6.5) = 6.5x
1x (10') 2
For the same situation at a 10' separation, using MACHINE-GUARD sensors:
E.G. = (38') 2 = 14.4 E.G. = (3x) (14.4) = 43x
3x* (10') 2
*Note: MACHINE-GUARD sensor range is the separation between emitter and receiver
where 3x excess gain remains.
