Benit String Sensor Depth Controller W2000 Road Milling Machine 2478077 2082170 2154440 101227

The Benit string sensor depth controller is an electronic control unit built for road milling machines that must hold an exact cutting depth across the full working width. As a direct replacement for reference numbers 2478077, 2082170, 2154440 and 101227, it restores accurate depth monitoring on W2000 class cold milling machines and keeps pavement removal, surface profiling and road rehabilitation work within tolerance.

Uneven cutting depth shows up later as loose material, over-milling of the base layer and extra asphalt consumption during paving. The string sensor design reads the reference line continuously and feeds that signal to the triple screen control panel, so the operator sees the actual depth while steering the machine. The result is uniform material removal, less waste and a smoother surface for the following paving pass.

• Triple screen display shows several machine parameters at once, cutting operator workload
• String sensor measurement with fast signal response for stable depth tracking
• Industrial electronic components rated for vibration, dust and moisture on site
• Plug-in replacement for OEM part numbers 2478077, 2082170, 2154440 and 101227
• Side mounting on the milling machine with the original bracket position
• Each unit function tested and inspected before packing

Contractors and equipment owners order this controller to bring a machine back into service quickly. Because the unit keeps the original connector layout and mounting position, a maintenance team can swap a failed controller without rewiring the machine. We ship from stock for urgent breakdowns and confirm the exact configuration against your machine serial number before dispatch.
