5.2 Mutual interference
Extra precautions are required while using two or more identical UST sensors because pulsed laser signals
from identical UST units could lead to false detection. Figures below show the installation method for
avoiding mutual interference.
a) Changing the height of installation
Displace the installation position up and down; mutual detection original point of the UST should be
separated 5 degrees or more from detection plane.
Figure 5-2 Opposite facing installation
Figure 5-3 Parallel installation
b) Changing the angle of installation
The installation angle of the UST is changed; mutual detection original point of the UST should be
separated 5 degrees or more from detection plane.
