APOLLO 2082170 Milling Sensor 2478077 Depth Controller with 2154440 Three-Screen Display

The APOLLO 2082170 milling sensor, 2154440 three-screen display and 2478077 depth controller form a complete, factory-matched control package for asphalt pavers and road milling machines. Supplied as a genuine APOLLO spare-parts set, the three components work together to deliver stable, repeatable depth readings and intuitive in-cab operation on demanding jobsites.

The 2082170 milling sensor is built around a sealed sensing element that resists dust, moisture and vibration. It provides fast, linear response to grade and slope changes, feeding clean signals to the controller so that the screed or milling drum holds the required depth without hunting. Its robust housing and weatherproof connector suit continuous operation in asphalt paving and cold-milling applications.

The 2154440 three-screen display presents depth, slope and status parameters on three dedicated screens, so operators can monitor all critical values at a glance without switching pages or navigating nested menus. Large, high-contrast readouts and clearly labelled keys shorten the learning curve and help crews make immediate corrections, keeping the paving or milling pass within tight tolerances.

The 2478077 depth controller is the processing heart of the set. It accepts sensor input, applies the selected grade or slope reference and drives the machine's height adjustment with precise, jitter-free output. Multiple operating modes cover both sensor-based and stringline work, and the automotive-grade electronics are protected against reverse polarity and short circuits for long-term reliability.

Because the three parts are engineered as one system, installation is straightforward: mount the display in the cab, fit the sensor to the machine's existing bracket, and connect the controller using the standard harness and plug-and-play connectors. No calibration hardware is required, and the familiar APOLLO interface means experienced operators can resume work quickly after a service or replacement.

Typical applications include APOLLO and compatible asphalt pavers and road milling machines used in highway resurfacing, trench and utility paving, and industrial floor milling. Each unit is inspected before dispatch and packed for safe export transport. Contact us with your machine model and serial number for a quick compatibility check and quotation.
