Paving Principles and Control Methods
P-32+ and P-32 Operator’s Manual P/ N: 1001547-01
Using a Slope Sensor allows you to evenly match the joints between passes over large areas.
Figure 29: Laser Control Setup
Your Topcon P-32+ or P-32 System uses a Slope Sensor mounted to the transducer beam on the paver to
measure and control the slope of the mat being laid (Figure 30). The sensor contains an electronic level vial,
that acts as a “precision carpenter's level”. Slope control with this electric level vial is very accurate and

If the required slope changes, the screed operator dials the new slope into the Control Box (Figure 31). The tow
point cylinder on the slope side raises or lowers until the Slope Sensor measures the new slope.

Cranking affects the relation between the Slope Sensor and the screed slope.
