Milesight - EM410-RDL
Radar Distance/Level Sensor


The Milesight EM410-RDL is a non-contact Radar Distance/Level Sensor that adopts Millimeter Wave Radar technology. By measuring millimeter-wave signals at higher frequencies, it provides more stable performance over longer distances, and is less affected by environmental conditions. It can detect the distance between the sensor and liquids of various types, unaffected by temperature, dust, condensate etc. With an IP68 waterproof and sealed enclosure, it can withstand the worst environments, while maintaining measurement accuracy, and does not require routine maintenance. Milesight offers LoRaWAN® and Cellular versions to meet different communication needs. TheLoRaWAN® version can be integrated with a Milesight LoRaWAN® gateway and the Milesight Development Platform, enabling remote and visual management of all sensor data. The Cellular version supports multiple application modes to be compatible with IoT platforms.

The EM410-RDL can be used in sewers, rivers, impounding reservoirs, storage tanks and other locations that require measurement distance and levels, especially of liquids.

Features

  • An 8° Radar beam angle can be focused on the target fluid, enabling accurate measurement of liquid level
  • Wide measuring range of 0.3m to 12m with small blind zone
  • Not affected by dust, condensation, temperature or acoustic noise
  • Non-invasive liquid level monitoring, can detect hazardous or non-hazardous liquids
  • Available in external or internal antenna versions for various applications
  • Built-in 3-axis accelerometer sensor to monitor device tilt status
  • Support to check radar-echo curve and one-click diagnostic to calibrate distance, ensuring accurate measurement under different environments
  • Supports blind zone alarm when the ranging results are within the blind zone
  • Enclosure made from PVDF material, offering excellent corrosion resistance, wear resistance and compressive strength for harsh environments
  • IP68 waterproof design, resistant in fresh water to a maximum depth of 1m for up to 48 hours
  • Thread design for common tank installation without extra accessories needed
  • Stores up to 2,000 historical records locally and supports retransmission to prevent data loss
  • Easy configuration via NFC and Bluetooth
  • Support management and OTA upgrade via Milesight Development Platform
  • Functions well with standard LoRaWAN® gateways and network servers
  • Supports multiple Cellular network protocols to be compatible with IoT platforms
