“Spring to Fall” Spraying with the flip of a switch!

The UC4 Sprayer Height Control system uses ultrasonic sensors mounted on the left, right and center boom, to automatically maintain a preset height of the entire boom above the ground or crop.

Fast and Reliable
For farm operators and custom applicators, speed can have a major impact on the bottom line. Manual operation of a sprayer in uneven field terrain may require reduced operating speeds for continual boom adjustments. The UC4’s ultrasonic sensors constantly (40 times per second) measure the distance to the ground. This information allows the UC4 system to make responsive height adjustments to allow your booms to automatically follow the contours of the land. The system is so dependable that it can allow an average speed of over 18mph in all kinds of uneven terrain.

More Efficient Use of Chemicals
The UC4 System maintains the booms at an entered preset height. Regulating spray nozzles at the recommended height above ground/crop results in the optimum spray pattern to disperse chemicals evenly and reduce drift.

Take The Stress Out of Spraying
After many hours of moving your head from side to side checking boom height, you can feel completely worn out. The Total Control System frees the operator of the most demanding part of the job. This level of comfort and control makes the operator’s job more efficient and less stressful.

Spray Day or Night
The UC4 ultrasonic sensors have been compared to “eyes” as they monitor changes in the field terrain. These ‘sonar’ devices do not depend on light conditions to measure boom height. Extend working hours well into the night, and take advantage of low wind conditions to spray in any light condition.

Avoid Boom Damage & Down Time
The UC4 control system takes over responsibility for monitoring field contours and making the constant boom adjustments. This allows you to keep your eyes on the job and focused on proper coverage and safety.

Sensor “Smarts”
The UC4 system can be set to read the boom height from the soil surface or from the top of the crop. The ultrasonic signal is “smart” enough to distinguish the ground from standing crop or field residue.

Accurate Smooth Spraying
The NORAC UC4 Control System uses the stepless output of proportional valves to provide a much greater and uniform level of boom control (minimizing boom rocking motion). Proportional valves enable the UC4 system to operate each boom independently. Height corrections are smooth, even, and automatic. . . and so is your spraying.

Intelligent, Durable, Easy-to-Use...

• Set-up is quick and easy with NORAC’s user friendly programming.
• Automatically maintains a preset height above the ground or crop.
• Displays the height (inches) that the nozzle tips are from the ground.
• Indicates whether the system is in Automatic “A” or Manual “M” modes.
• Communicates hydraulic valve activity.
• Can be manually overridden at any time with boom up/down switches.
• Adjust your spray nozzle height on the go, with the flip of a switch.

Rugged, Reliable Non-Contact Ultrasonic Sensors

• Rugged aluminum sensor design for trouble free use.
• Internal electronics are epoxy sealed making them virtually impervious to moisture damage.
• Distinguish changes in height to the nearest half inch.
• Monitor the top of the crop or the ground surface.
• The sensor is able to distinguish the ground surface from standing crop or field residue.
• For total boom control, a sensor is mounted on each boom section.
• Breakaway brackets have been designed to provide superior protection to the sensors; the mounting will bend back approximately 90 degrees.
• High performance sensors provide 40 readings per second to give instant
  response.

Custom Hydraulics and Cabling

• A separate proportional valve is used for each boom to ensure smooth independent hydraulic control.
• Each kit includes custom designed hoses, fittings and cable harnesses to fit
  most models of sprayers.
  (Although NORAC attempts to supply complete installation kits some modifications may be required due to sprayer manufacturing variations outside of NORAC’s control.)
