Boom Options
Three Tier System (3TS)
The Three Tier System (3TS) consists of two
complete and totally separate boom lines on the
same boom frame. As an example a conventional
30 metre boom has one boom line with 60 nozzle
outlets (2 per metre) across its width. A 3TS boom
replicates this first line with a second line also
consisting of 60 nozzles giving a total of 120 nozzles
for both lines.
In simple language, the 3TS gives you the capacity
to vary application rates and speeds by switching
extra nozzles on and off. The 3TS allows a
range of speed changes without the spray quality
being compromised – the correct droplet size is
maintained.
Importantly you can use the nozzles you want to
use - including air induction nozzles. That means
higher speed spraying without the limitations of large
droplet size.
Typically nozzles on the first line may flow at 015
flow rate and the nozzles on 3TS’s second line at
025. When spraying, the first nozzles automatically
switch off when they reach full operating pressure
allowing the second line nozzles to commence
spraying. As speed increases again and the second
line nozzles reach their maximum operating pressure,
the first line nozzles will switch on again.
Thus, the flow rates of 015, 025 and 040 can be
achieved while maintaining the optimum droplet size
and spraying pressure. The 3TS delivers everything
needed for precision application at variable speeds.
Boom Height Control - Norac
Boom Height Control systems maintain the boom
at a preset height by monitoring field contours and
making responsive boom adjustments. Using data
from either 3 or 5 ultrasonic sensors, the Boom
Height Control systems makes responsive height
adjustments allowing booms to automatically follow
the contours of the land Maintaining spray nozzles at
the recommended spray tip height allows chemical
to be applied using an optimum spray pattern
providing even application and reducing drift.
Boom Height Control reduces the need for the
operator to move their head back and forth to
monitor changes in field terrain, thereby reducing
stress and fatigue.
This allows the operator to focus on machine
operation and safety. Manual operation of a sprayer
in uneven field terrain may require reduced
operating speeds for continual boom adjustments.
Ultrasonic sensor hardware and software is
designed specifically for height control applications.
The ultrasonic signals can distinguish the difference
between the ground and standing crop or field
residue. Boom height is controlled by choosing Soil
Mode (senses the soil surface), Crop Mode (senses
the top of the crop), or Hybrid Mode (technology
that calculates a virtual top of the crop for more
accurate control).
Refer to manufacturer’s manual(s) for detailed
information about this system.
