A new wire string sensor has been released for the leveling systems of milling machines and asphalt pavers. Carrying the interchangeable reference numbers 05940023, 392-9002 and 04-21-30070, this precision component provides the accurate positional feedback that keeps grade control loops working within tight tolerances on the job site.

In milling and paving operations, the string sensor is the "eye" of the leveling system. It continuously reads the reference line or string and reports position back to the controller, which adjusts the machine to maintain a consistent depth and grade. When the sensor drifts, wears out or fails, the result is uneven surfaces, wasted material and expensive rework.
This replacement wire string sensor restores the accurate, repeatable signal that the control loop depends on. Operators get smoother drum and screed movement, better surface regularity and fewer unplanned stoppages during a shift.

The sensor is suited to the leveling systems of asphalt pavers, milling machines and road rollers. It performs reliably across asphalt, concrete and mixed pavement surfaces, and it is a practical choice for routine maintenance, worn-part replacement or full fleet upgrades. Because the reference numbers are interchangeable, distributors and fleets can standardize on a single sensor that covers a broad range of equipment.
The wire string sensor 05940023 / 392-9002 / 04-21-30070 is now available with a minimum order quantity of just one piece, at USD 1120 per piece. Supply ability reaches 10,000 pieces per month, with a delivery time of 7-10 days, and each unit is packed in a sturdy box for safe transport and backed by ISO 9001:2015 quality control.
Distributors, equipment dealers and road construction contractors looking for a reliable replacement leveling sensor are invited to contact the supplier for a quotation, volume pricing and fitment confirmation.
