Ultraääni-etäisyysanturi Milesight EM500-UDL-868M-W100 — 10 m kantama, langaton 868 MHz

The Milesight EM500-UDL-868M-W100 is an ultrasonic distance level sensor designed for non-contact measurement up to 10 meters. It delivers continuous distance and level data via wireless 868 MHz communication, enabling remote monitoring of liquid or solid surfaces without physical contact. The sensor is suitable for installations where reliable, maintenance‑free distance sensing and periodic or continuous reporting are required.

Advantages

The sensor provides accurate non-contact measurement across its 10 m range and supports wireless data transmission on the 868 MHz band for integration with remote monitoring systems. Its configuration options and stable ultrasonic measurement make it suitable for environments where direct contact is undesirable. The device is built for straightforward installation and continuous operation, offering consistent readings for automation, alerting and logging systems.

Suitable for

• Tank and silo level monitoring
• Open-channel depth and flow sensing
• Flood and water level monitoring in basins and sumps
• Proximity detection for objects or materials up to 10 m
• Remote site monitoring where wireless 868 MHz connectivity is required

Key specifications

• Measurement principle: Ultrasonic non-contact distance sensing
• Maximum measurement range: 10 m
• Communication: Wireless 868 MHz
• Output: Continuous distance/level readings suitable for remote reporting
• Installation: Fixed mount with straightforward alignment
• Typical use environment: Liquids and solids in open tanks, channels and outdoor sites

How to use

Mount the sensor above the measured surface with a clear acoustic path and set the measurement interval and reporting parameters through the device configuration interface or compatible gateway. Ensure the sensor is aligned perpendicular to the target surface and positioned within the 10 m effective range. For continuous monitoring, connect the sensor to the 868 MHz network and configure thresholds for alerts or data logging in the receiving system.

Recommendations

Position the sensor to avoid obstructions and strong turbulence at the measurement surface; allow a stable field of view and maintain recommended mounting height. Verify regular firmware and configuration updates via the network gateway and validate readings after installation to confirm expected performance for the specific application.
