Apollo S1900-3L 2484809 Ultrasonic Level Sensor Restores Paver Automatic Levelling Accuracy

Apollo S1900-3L 2484809 Ultrasonic Level Sensor Back in Stock for Asphalt Paver Levelling Systems

A new supply of the Apollo 2484809 ultrasonic level sensor has arrived, giving contractors, repair workshops and equipment dealers a high precision replacement for the levelling circuit of the S1900-3L asphalt paver. Each unit is 100% new, comes from Japan and is inspected before packing, so a machine that has lost grade accuracy can be brought back into tolerance without waiting for a long lead time or reworking the mounting bracket.

Why the Levelling Sensor Decides Mat Quality

Automatic grade control only works when the sensor feeding the screed controller delivers a clean, repeatable signal. Once the sensor drifts, the operator has to correct manually, and the result appears quickly in the finished mat as waves, depressions and unnecessary mix consumption. The 2484809 avoids that decline with a design built around site reality:

• Non-contact ultrasonic measurement: the sensor reads distance to a skid, wire rope or the existing mat without touching the reference, so there are no sliding parts to wear and no errors from loose aggregate on the surface.
• Machine-specific fit: dimensioned for the S1900-3L paver and identified by part number 2484809, which removes the risk of fitting a wrong sensor during a breakdown repair.
• Sealed industrial housing: protects the electronics against radiant heat from hot mix, dust, water spray and continuous machine vibration.
• Filtered stable output: keeps the controller from chasing noise, so the screed responds smoothly rather than in steps.
• Simple maintenance: routine care is limited to wiping the sensor face and checking the connector, which keeps machine availability high.

Technical Specifications

Field Applications

The sensor is used where tolerance and output consistency matter most: highway and expressway paving, airport apron and runway work, municipal road rehabilitation, industrial yards and port pavement. It also suits rental fleets that keep a fast-moving stock item covering the S1900-3L paver, because a single failed sensor can otherwise stop a paving train for days while a part is sourced.

Commercial Terms and Delivery

Single-piece orders are accepted for urgent breakdowns, and consolidated shipments are arranged for distributors holding stock across several machines. Every consignment ships with commercial invoice and packing list for straightforward customs clearance by air freight or courier.

Ordering Support

Before confirming an order, our spare parts team verifies the machine model, serial number and part number against the part on the machine, so the correct sensor arrives the first time. Send a photo of the original sensor together with the paver model and we will confirm compatibility within one working day.
