2039585 Gradient Meter Mechanical Leveling Instrument for S1800 S1900 Asphalt Paver Sensor

Precise screed control is the difference between a smooth, well-compacted mat and an expensive rework. The 2039585 gradient meter is a mechanical leveling instrument built for the electrical leveling system of S1800 and S1900 asphalt pavers. As a direct replacement grade sensor, it converts pavement elevation changes into reliable electrical feedback, allowing the paver to hold a constant layer thickness and slope across the full paving width.

Key Features of the 2039585 Gradient Meter

• Mechanical measuring principle: the sensing arm follows a tensioned reference wire or existing pavement, so the reading stays stable in dust, water mist and high humidity.
• Precise signal output: mechanical displacement is converted into an electrical feedback signal for the control panel and hydraulic system.
• Rugged steel housing: engineered to resist the vibration, impact and radiant heat produced by hot asphalt mix.
• True drop-in replacement: mounting dimensions and electrical interfaces match the original part number for fast, tool-light service.
• Reliable in the field: consistent elevation and slope control keeps layer thickness uniform and reduces material waste.

Technical Specifications

How the Mechanical Leveling System Works

Unlike ultrasonic or electrolytic sensors, the 2039585 does not depend on sonic emission or tilt sensing. Its purely mechanical mechanism detects changes in pavement elevation through direct contact between the sensing arm and a reference surface. The displacement measured by the arm is translated into an electrical signal and sent to the control system.

The operator's target slope is continuously compared with the actual detected value. The system then drives the leveling cylinder to raise or lower the screed in real time. Because corrections happen automatically while the paver moves forward, the finished surface keeps a consistent grade and a smooth finish even over long runs.

Applications

• Highway and expressway asphalt paving
• Municipal road construction and resurfacing
• Airport runway and apron paving
• Large-area parking lots and industrial yards
• Paver maintenance, overhaul and spare-part stock

Because the unit is designed to match original mounting points and wiring, maintenance teams can swap out a failed gradient meter on site without re-engineering the machine. Periodic inspection of the sensing arm wear and a simple recalibration are usually all that is required to keep leveling accuracy within tolerance.

Why Buy the 2039585 Gradient Meter

After-market spare parts should behave like original equipment. This leveling instrument is produced for road construction fleets that demand dependable performance, predictable lead times and a clear price. With a compact steel body, matching interfaces and a proven mechanical design, it is suited to both emergency replacement and planned stocking.

About the Supplier

The unit is supplied by a road-construction parts manufacturer based in Taicang, Suzhou, focused on after-market components for asphalt pavers, milling machines and road rollers. The product line covers paver control panels, sensors, remote controls, track undercarriage, milling picks, track rollers, rubber mounts and spray nozzles — giving contractors a single source for the consumables that keep a paving train running.

Availability and Ordering

The 2039585 gradient meter is available from a low minimum order quantity, with short lead times on stock items and negotiable terms for larger projects. Standard export packing protects the sensor during transit, and technical support is available to help match the correct part to your machine.
