Benit String Sensor Depth Controller Keeps W2000 Road Milling Machines On Depth

Milling depth is the number that decides whether a rehabilitation job meets specification or comes back as a claim. When a cold milling machine drifts a few millimetres off the reference line, the base layer is over-cut, extra asphalt is ordered, and the paving crew spends the next shift correcting a surface that should have been finished. The Benit string sensor depth controller was built for contractors who cannot afford that drift. It is a direct electronic replacement for reference numbers 2478077, 2082170, 2154440 and 101227, and it restores accurate depth monitoring on W2000 class road milling machines without rewiring or fabricating brackets.

Why Accurate Depth Control Pays for Itself

Depth errors are expensive in three ways. First, material: every extra millimetre of cutting depth becomes additional asphalt that has to be bought and laid. Second, time: crews that stop to re-check depth lose production hours on a machine that costs money by the minute. Third, quality: an uneven cut leaves a surface that paving cannot fully correct, which shows up in compaction tests and final acceptance.

The string sensor design reads the reference line continuously and sends a stable signal to the control panel, so the operator sees the actual cutting depth while the machine is moving, not after the pass is complete. Because the reading is displayed on a triple screen panel, depth information sits next to the other machine parameters the operator already watches, which reduces the number of glances away from the cutting edge.

Key Features of the Benit String Sensor Depth Controller

• Triple screen display that shows depth and other machine parameters at the same time
• Fast signal response from the string sensor for stable depth tracking on uneven surfaces
• Industrial electronic components selected for vibration, dust, moisture and temperature swings on site
• Plug-in replacement layout that keeps the original connector position and mounting points
• Side mounting on the milling machine using the existing bracket location
• Function tested before packing, with inspection records kept for every production batch

Compatibility and Technical Data

Built for Field Replacement, Not Workshop Downtime

Most controllers are ordered because a machine has stopped, and the clock started when the fault appeared. Because this unit keeps the original connector layout, a maintenance team can swap a failed controller in the field using hand tools, then verify depth control against a test section before the machine returns to full production. Suppliers who keep the part on the shelf shorten that window from weeks to days.

Suzhou Benit Machinery Technology Co., Ltd has spent more than fifteen years manufacturing and distributing road equipment spare parts, including track pads, screed plates and electronic control components. Production runs through automatic lines with in-process inspection, and every controller is checked for function, stability and output accuracy before it is packed. For buyers running mixed fleets, the same inspection routine applies whether the order is one unit for an emergency repair or a batch for a maintenance programme.

Ordering and Technical Support

To confirm compatibility, send the machine model, serial number and the part number printed on the failed controller. Our team will verify the configuration, confirm stock, and quote FOB Shanghai, EXW Taicang or CIF to your destination port. Payment terms of TT, LC at sight and DP are negotiable case by case, and shipments can move by air freight, rail or sea depending on how quickly the machine needs to be back in service.

Air freight is the usual choice for a single controller on a stopped machine. Sea freight and rail become more economical for maintenance programmes that cover several machines or a full season of spare parts. Either way, we pack the unit in a protective carton with pallet or wooden box support so it arrives in the same condition it left the workshop.
