Product description

The EM400-UDL is a state-of-the-art ultrasonic distance sensor designed for non-contact level measurement of liquids and solids. This device is the perfect solution for cost-effective, efficient monitoring in water infrastructure, storage tanks, or industrial silos. Thanks to its versatility, it offers multiple selectable probes with detection ranges adapted to various depths and operational needs.

Equipped with an IP67 waterproof housing and internal moisture-proof coating, the EM400-UDL is built to withstand demanding outdoor conditions and harsh industrial environments. In addition, it integrates smart temperature sensors and a 3-axis accelerometer, allowing it not only to measure levels, but also to monitor device tilt and issue safety alerts in case of thermal anomalies.
