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.

• 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.

• 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.

• 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.
• 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 downtime.
