Description

The Milesight EM400-UDL is a carrier-grade LoRaWAN Ultrasonic Distance Sensor designed for non-contact level monitoring in demanding outdoor and industrial scenarios. This versatile device supports multiple probe options, enabling precise measurement ranges from 25cm up to 10 meters, making it suitable for everything from water tanks to large grain silos. Built for long-term autonomy, it features a 3-axis accelerometer to monitor device tilt and an NTC temperature sensor for early fire detection. Its ruggedized IP67 enclosure and ultra-low power design allow for up to 10 years of maintenance-free operation on dual 9000mAh batteries.

Industrial Precision & Durability

Selective Probe Technology Choose from multiple transducer versions (Standard, CO2, Snow) to match specific environmental requirements and measurement distances.
Rugged Outdoor Design The PCBA is treated with a damp-proof coating and housed in an IP67 flame-retardant enclosure to withstand moisture, dust, and UV exposure.

Professional Monitoring Scenarios

• Water Level Management: Monitor reservoirs, rivers, and open channels for flood prevention and water resource planning.
• Silo & Tank Monitoring: Accurate fill-level tracking for grain, animal feed, or liquid chemicals in industrial storage.
• Smart Waste & Snow: Measure garbage levels in large communal bins or track snow depth for municipal safety.
