Speed Sensor for Sprayer
The speed sensor and speed ring are located at the inside of the sprayer’s right wheel. The sensor is an inductive type that
requires a metallic protrusion like a speed ring to pass by it to trigger a signal.
Adjustment (Sprayers built before 1/1/2020)
1. Assure that the speed ring is correctly fitted to the wheel, so that
the arrow (A) follows the rotation of the wheel in the forward
driving direction.
2. Check that the sensor lines up in the (radial) center of the air gaps
from bottom/inside to top/outside of the speed ring.
3. If necessary, adjust plate on axle.
4. Adjustment of air gap (B) begins with the sensor directly opposite
one of the carriage bolts holding the speed ring.
5. Adjust air gap (B) to 1/8” (3.0 mm). Use feeler gauge or similar tool.
6. After adjustment, rotate the wheel. Verify air gap variation of less
than +/-0.02” (+/-0.5 mm). Check this for the entire circumference.
7. Verify the speed on the controller.
ATTENTION! Correct fitting is indicated by continuous flashing
from the transducer when the wheel rotates.
Adjustment (Sprayers built after 1/1/2020)
1. Assure that the speed ring is correctly fitted to the wheel, so that
the arrow (A) follows the rotation of the wheel in the forward
driving direction.
2. Check that the sensor lines up in the (radial) center of the air gaps
from bottom/inside to top/outside of the speed ring.
3. If necessary, adjust plate on axle.
4. Adjustment of the air gap (B) begins with the sensor directly
opposite one of the carriage bolts (C) holding the speed ring.
5. Loosen the clamp (D) to move the sensor (E) in or out of the red
tube. Re-tighten the clamp when finished.
6. Adjust the air gap (B) between sensor and speed ring to 5/32”
(4 mm). Use a feeler gauge or similar tool.
7. After adjustment, rotate the wheel. Verify air gap variation of less
than +/-0.02” (+/-0.5 mm). Check this for the entire circumference.
8. Verify the speed on the controller.
9. ATTENTION! Correct fitting is indicated by continuous flashing
from the transducer when the wheel rotates.
