Slope sensor mounting
Mounting the
sensor
It’s important to take care when installing sensors that measure a slope.
If they are not aligned with the axel that they are supposed to measure
they will have an error in the measurement, and that will result in inaccu-
racy in the final grade.
This chapter will discuss the things that need to be focus on when
mounting sensors that measure a slope.
The sensors in question are:
•
Cross slope sensor (single & dual)
•
Mast slope sensor
•
Main fall sensor (junction box)
•
Rotation sensor
Calibration offset
It is always a recommended to have the calibration offset as close to 0.0%
as possible.
When mounting a cross slope sensor on a blade it should be mounted
level when the blade is level.
If the sensor is mounted with a large calibration offset it will cause a
misreading of the slope when the machine is driving up or down hill, or
the mast is tilted. This misreading will end up as a height error in the auto-
matic grading.
Sensor alignment
Because the sensor only can measure the slope in one direction it’s
necessary to make sure the sensor is mounted parallel to the direction
that you want to measure the slope.
The mainfall sensor is designed to measure if a grader is driving up or
down hill, but if the junction box is mounted so that it’s pointing to the
side it will not measure the right mainfall. Therefore it’s important to
mount the junction box so that it’s parallel with the gooseneck.
