4.2 Height Sensors
• Height sensors use an ultrasonic signal to measure distance to the ground or crop canopy.
• Most standard systems have two height sensors. One mounted on the outer part of each
boom tip. However, there can be as many as six sensors per system.
• Height sensor firmware version must be 2.0.0.1 or higher.
4.3 Roll Sensors
• Roll sensors are important for measuring boom and sprayer roll dynamics.
• Two roll sensors are normally used for a UC4.5 Spray Height Control System.
• The mounting position of the roll sensors vary from sprayer to sprayer depending on
boom geometry and suspension.
• Roll sensor firmware version must be 2.0.0.0 or higher.
