APOLLO Cross Slope Sensor Digi-Slope II CAN PWM 157449/04-21-20020 for Asphalt Paver

APOLLO Cross Slope Sensor Digi-Slope II Brings Precise Grade Control to Asphalt Pavers

APOLLO has introduced the Cross Slope Sensor Digi-Slope II, a high precision component for the electrical system of asphalt pavers, supplied under part numbers 157449 and 04-21-20020. Sitting at the heart of automatic slope control, the sensor reads the transverse inclination of the paver screed in real time and converts mechanical slope changes into stable electrical signals for the control unit, so the screed holds a uniform cross slope without manual measurement.

Cross slope is one of the details that separates a good mat from an average one. Get it wrong and water pools on the surface, ride quality suffers and the job may fall outside specification. The Digi-Slope II keeps that variable under control, pass after pass.

Precise Sensing with CAN and PWM Output

The sensor pairs a precision measurement element with digital signal processing to deliver resolution down to 0.001° and accuracy of ±0.02°. That level of detail lets the leveling system react to small slope changes before they show up in the mat. The unit supports both CAN and PWM signal output, so it integrates flexibly with the paver's control architecture.

A built-in temperature compensation module keeps readings stable across a wide working range, from -40°C to +85°C, reducing drift as conditions change through the day. The result is dependable slope detection even under vibration and dynamic paving loads.

Technical Specifications

Application and Service

As a direct replacement part, the Digi-Slope II keeps the original electrical interface and mounting dimensions, so fitting to the paver electrical system is straightforward. It suits asphalt pavers and related paving equipment used on outdoor projects, where accurate cross slope control is essential to mat quality and to meeting road construction tolerances.

Upkeep is simple. Keep the connector clean, check the mounting for play, and confirm the slope readings respond correctly before each shift. A little routine attention keeps the leveling system performing to specification over the long haul.
