HY-RSS11E

Professional Non-Contact Road State Sensor

A high-performance non-contact road surface sensor for safety-critical applications. Measures water, ice and snow thickness up to 10 mm and supports a wide 2–13 m installation range — ideal for bridges and elevated roadways.

0–10 mmBridges / elevatedMODBUS-RTU

The professional-grade head in the HY-RSS road state family. The 2–13 m measuring range covers high-mast gantries and bridge installations where a closer-range sensor would not reach the deck. Reports six road states, three layer-thickness channels (water / ice / snow), grip level and surface temperature over a single MODBUS-RTU link.
