lorawan® Radar Distance/Level Sensor EM410-RDL

EM410-RDL Radar Distance & Level Sensor – Millimeter-Wave Accuracy for Harsh Environments

The Milesight EM410-RDL is a robust radar-based distance and level sensor designed for non-contact monitoring of liquids and smooth-surfaced solids in extreme conditions. Powered by millimeter-wave (60GHz) radar technology, it offers precise and stable measurements even in environments with dust, condensation, noise, or temperature fluctuations. With an 8° beam angle and up to ±2 mm accuracy, it is ideal for water tanks, sewage, reservoirs, seawater/brine tanks, and more. The EM410-RDL is available in both lorawan® and Cellular versions to meet diverse communication needs.
