APOLLO has added a new high accuracy asphalt paver sensor to its leveling range for the S1900-3L paver series, supplied under part number 2484809 2647949. The unit is a convenient ultrasonic level sensor that feeds real-time elevation readings to the paver's automatic leveling system, helping crews hold a consistent grade and slope across every pass.
Because the sensor measures the reference surface without touching it, the paving train keeps moving without the interruptions that come from manual checks. For contractors working long shifts on highways, urban roads and industrial yards, that translates into a smoother mat and fewer costly corrections.

Grade and slope control lives or dies on the quality of the elevation signal. The Apollo sensor is engineered to deliver that signal reliably, even as dust, heat and vibration build up over a working day. Its output integrates directly with the paver's control system, so the screed reacts quickly when the reference surface changes.
The result is fewer manual adjustments, more consistent mat thickness and measurable savings on mix. Operators also report less fatigue, because they can trust the leveling system instead of constantly watching the grade.

A paver's leveling sensor works in one of the toughest spots on any road project. Fresh asphalt radiates heat, dust hangs in the air, and the machine vibrates constantly. The Apollo ultrasonic level sensor answers those conditions with a sealed, rugged enclosure and industrial-grade electronics that keep the measuring signal stable.
Upkeep is simple. Keep the sensor face clean, inspect the connector and cabling, and confirm the leveling system responds correctly before each shift. That routine protects the accuracy that makes the 2484809 a dependable replacement part for S1900-3L pavers.
The Apollo High Accuracy Asphalt Paver Ultrasonic Level Sensor is available now with a minimum order quantity of one piece and a price of USD 1425 per piece. Payment can be arranged by L/C, T/T or Western Union, supply ability stands at 1000 pieces per month, and standard delivery runs in 7 to 10 days in box packaging.
