Sensors

Pitch Sensor ( AS21)

Illustration 10	g01864734
AS21 Pitch Sensor (53) Output Connector (54) Input Connector

The pitch sensor measures the slope of the machine in relation to the front of the machine.

Illustration 11 shows the pinout information for the 6 pin socket receiver on the cable connector that connects to the pitch sensor.

AS400 Angle Sensor (Roll)

The AccuGrade System uses a AS400 Angle Sensor in order to determine the roll of the machine (side to side angle measurement of the car body). The AS400 is a single axis sensor.

Front Linkage Position Sensors (Position Sensing Cylinder and Rotary Sensors)

Rotary Position Sensors

The AccuGrade system uses two rotary position sensors that are located on the boom and the stick in order to measure the relative rotation angle between the two linkages.

Position Sensing Cylinder (PSC)

The "Position Sensing Cylinder" (PSC) measures the rod extension and retraction of the hydraulic cylinder for the bucket. The PSC uses a sensor that is integrated into the cylinder in order to make this measurement.
