Introduction

The APOLLO 2197266 is a high-precision, non-contact ultrasonic sensor specifically engineered for the demanding environment of road construction, particularly as a critical component on asphalt pavers. It serves as a direct, high-quality replacement for original manufacturer sensors, ensuring the machine maintains its ability to lay asphalt with exceptional accuracy and consistency.

This sensor is a fundamental part of the paver's automated grade and slope control system, which is responsible for creating a smooth, level mat of asphalt with the precise cross-slope and longitudinal grade required by the project specifications.

Key Features & Benefits

1. High-Precision Measurement:

   • Utilizes ultrasonic technology to accurately measure the distance from the paver to a fixed reference (e.g., a steel skid or a wire rope) or to the surface of the previously laid mat. This data is continuously fed to the paver's control system to automatically adjust the screed's height and angle.

2. Non-Contact Operation:

   • Unlike mechanical followers that ride on a reference surface, this sensor measures without physical contact. This eliminates wear and tear from friction and provides a consistent reading unaffected by surface irregularities or debris.

3. Robust Construction for Harsh Environments:

   • Built to withstand the extreme conditions of an asphalt paving site, including:

     • High Temperatures: Resistant to heat from the hot mix asphalt.

     • Dust and Debris: Sealed housing protects internal components from dust, dirt, and moisture.

     • Vibration and Shock: Engineered to endure the constant vibration and jolts of the moving paver.

4. Easy Installation & Compatibility:

   • Designed as a direct replacement for common OEM sensors used by major paver manufacturers like Volvo, Dynapac, Bomag, and others (always verify model compatibility).

   • Typically features a standardized mounting bracket and electrical connector for a plug-and-play installation, minimizing
