04-03-00415 Sonic Sensor Leveling System Big Ski Junction Box Asphalt Paver Sensor Replacement

This sonic sensor leveling system is a direct replacement spare part for asphalt paver screed control. The assembly combines a non-contact sonic sensing head with a big ski junction box and wiring harness, keeping paving mat thickness stable while the machine moves over uneven base layers.

• Non-contact sonic sensing — reads the reference surface without touching it, so the sensor keeps working over hot mix and tacked surfaces.
• Big ski junction box — widened ski housing holds the sensing unit steady and protects the wiring terminal block from dust and vibration.
• Plug-in wiring harness — pre-assembled connector block shortens replacement time on site.
• Stable height control — consistent signal output helps the screed hold mat thickness and slope across the full paving width.
• Robust housing — sealed metal and engineering plastic body resistant to heat, asphalt spray and daily jobsite vibration.

Each sensor set is packed in a carton with shock-proof foam, then reinforced in an export wooden case for long-distance transport. Orders are ready in 2–3 working days after payment, shipped from Shanghai port by air or sea.
