APOLLO 2462560026 Slope Sensor Paver Pendulum Position Sensor For s1800/s1600 Paver

Key Function & Operating Principle

1. Core Function: The sensor's main purpose is to detect and feedback the cross-slope angle of the screed. Cross-slope refers to the transverse inclination of the road surface relative to the horizontal plane, usually expressed as a percentage, and is essential for ensuring proper water drainage.

2. Operating Principle:

   • Physical Connection: The sensor is connected to the paver's tow arms or reference beam (e.g., an averaging beam) via a mechanical pendulum arm.

   • Position Sensing: As the paver moves during operation, variations in the ground level cause the tow arms to raise or lower. This movement is transmitted through the pendulum arm to the sensor, causing the internal shaft of the sensor to rotate.

   • Signal Conversion: A precision potentiometer or encoder inside the sensor converts the shaft's rotation angle (i.e., the pendulum position) into a corresponding change in resistance or a voltage signal.

   • System Control: This electrical signal is sent to the paver's control console. The console compares the real-time signal with the target cross-slope value set by the operator. If a deviation is detected, the console issues a command to automatically adjust the hydraulic cylinders on one side of the screed, thereby correcting the screed's tilt angle to maintain the set cross-slope.

Key Features

• High Precision & Reliability: Provides accurate position feedback, which is fundamental for ensuring paving quality (smoothness, cross-slope accuracy).

• Rugged Construction: Designed for harsh construction site environments, capable of withstanding vibration, dust, and temperature fluctuations.

• Direct Replacement: This model is a direct replacement for the original factory part, ensuring perfect compatibility with the hydraulic and control systems of S1800/S1600 series pavers, ready for plug-and-play installation.

• Analog Signal Output: Typically provides an analog voltage or resistance signal proportional to the pendulum arm angle, which is a standard and reliable interface for paver control systems.

Importance in Paving Operations

During paving, this sensor acts as a "command unit":

• Ensures Accurate Cross-Slope: Automatically maintains the set cross-slope (e.g., 1.5% or 2%), avoiding the instability of manual operation and ensuring road drainage meets design requirements.

• Improves Smoothness: By quickly responding to ground variations and making automatic adjustments, it effectively reduces longitudinal and transverse waves, significantly enhancing the ride comfort of the pavement.

• Increases Efficiency: Automated control reduces the reliance solely on operator experience, lowers labor intensity, and helps maintain a continuous, high-efficiency paving speed.
