The pull wire sensor (also called string potentiometer or wire rope sensor) is the core feedback component of the leveling control system on W2000 and W1900 cold milling machines. It converts the vertical movement of the machine side plate into an electrical signal, allowing the automatic leveling system to keep the milling depth accurate on uneven asphalt and concrete surfaces.
This unit is a direct replacement for OEM part numbers 161455, 2137341 and 04-20-30070, and is fully interchangeable with the original sensor on W2000 and W1900 cold milling machines as well as common asphalt paver leveling systems. Every sensor is 100 percent new, bench tested before packing, and protected in a silver plated housing for reliable performance in dusty, vibrating job site conditions.
