The Milesight EM410-RDL-L0CEU is an advanced Cellular 4G radar distance and level sensor designed for highly accurate, non-contact measurement of liquid and solid surface levels in industrial, environmental, and smart infrastructure applications. Leveraging 60 GHz millimeter-wave radar technology, the EM410-RDL delivers reliable measurement results even in harsh, dusty, or noisy conditions.
With a narrow 8° radar beam, it focuses measurements on the target surface while minimizing interference from surrounding elements. The rugged IP68-rated PVDF enclosure provides excellent resistance to water (up to 1 m/48 hr), corrosion, and wear — ideal for outdoor and industrial environments. Configuration is simple via NFC and Bluetooth, and the sensor includes a built-in 3-axis accelerometer for tilt detection and alerts.
Powered by a large 19,000 mAh ER34615 Li-SOCl₂ battery, the EM410-RDL can operate for up to 7 years in Cellular mode, making it suitable for long-term, maintenance-free deployments in remote locations such as sewers, rivers, tanks, reservoirs, and industrial sites.
