We are pleased to announce the release of a new spare part for road milling professionals: the APOLLO Wire String Sensor, Part No. 2137341 / 161455 / 04-20-30070. Designed as a precision member of the W2000 milling machine grade control system, this wire string sensor keeps milling depth and grade accurate pass after pass.
Technically known as a string potentiometer or string encoder, the APOLLO Wire String Sensor converts mechanical linear displacement into an electrical signal. Inside, a precision potentiometer or encoder works with a high-strength cable wound on a spring-loaded spool, delivering a stable and repeatable reading that the machine’s control system can rely on. For contractors who measure quality in millimeters, that stable signal is what separates a smooth, uniform milled surface from an uneven one.

On road milling and cold planer projects, the sensor is the link between the reference wire and the cutting drum. When that link is precise and uninterruped, the machine removes exactly the intended depth of material, which protects the underlying base and prepares a uniform surface for the new asphalt layer. A drifting or noisy signal, by contrast, leads to over-cutting, wasted material and expensive rework. The APOLLO wire string sensor is built to hold its accuracy in the demanding conditions of a live milling site.
Because the unit is matched to the APOLLO W2000 system, mounting and electrical interfaces align precisely, reducing installation time and avoiding the calibration problems that come with incompatible replacements.
The APOLLO Wire String Sensor 2137341 / 161455 / 04-20-30070 is available now with a minimum order quantity of one piece and short lead times. Each unit is packed for safe export delivery. For compatibility confirmation and a quotation, please contact our team directly.
