NORAC ultrasonic sensors are designed to work best in the brackets
provided (
Figure 2
). If you decide to use a different style of sensor mount,
you may limit the performance of the sensor and/or void your warranty.
Further, it is important to follow the guidelines in the UC4+ Installation
Manual for mounting the sensors. The sensors should be at least 25 cm (9
inches) above and 25 cm (9 inches) in front of the spray nozzles.
For large boom or severe terrain applications, an additional sensor may be
mounted near the midpoint of each boom to obtain an average height
reading. The average height reading will provide improved height control
over the length of the boom, and protect the boom in severe terrain
conditions (
Figure 3
).

On sprayer models with main frame roll capability (
Figure 4
), the main
boom sensor can also be used to adjust the roll angle of the entire boom.
Alternatively, roll sensors can also be used to adjust the main roll angle of
the entire boom. Addition of this sensor to the UC4+ Spray Height Control
system can greatly improve the speed and stability of the automatic control
actions. Contact NORAC for more information on the availability of roll
control for your sprayer model.
