Another good reason for the main boom sensor is that soil conditions change
along with the weight of the machine. As the level of fluid in the tank of the
sprayer changes throughout the day and soil conditions vary, the height of the
center boom will change because of the amount the tires sink into the soil.
Special attention must be taken into consideration when mounting the center
sensor, as explained in Section 4.3.
Norac ultrasonic sensors are designed to work best in the brackets provided
(shown above). 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 Installation Manual provided
with your kit for mounting the sensors. The sensors should be at least 9
inches above and 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 (see
Figure 3).

On sprayer models with center frame roll capability (as illustrated in Figure
4) the center boom sensor can also be used adjust the roll angle of the entire
boom. Addition of this sensor to the UC4 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.
