Milesight EM410-RDL Radar Distance/Level Sensor 12m Range
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 liquid of various types, unaffected by temperature, dust, condensate etc. With IP68 waterproof and sealed enclosure, it can withstand the worst environment, while maintaining measurement accuracy, and does not require routine maintenance. Milesight offers LoRaWAN® version and Cellular version to meet different communication needs. The LoRaWAN® version can be integrated with Milesight LoRaWAN® gateway and 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. EM410-RDL can used in sewers, rivers, impounding reservoirs, storage tanks and other locations that require to measure distance and level.
Features
- 8° Radar beam angle can be focused on the target fluid, enabling accurate measurement of liquid level
- Wide measuring range 0.3m to 12 with small blind zone
- Not affected by dust, condensate, temperature, acoustic noise, etc
- Non-invasive liquid level monitoring can detect hazardous or non-hazardous liquids
- External antenna or internal antenna versions are optional 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 the distance, ensuring accurate measurement under different environments
- Support blind zone alarm when the ranging results are within the blind zone
- Adopt 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
- Store up to 2,000 historical records locally and support retransmission to prevent data loss
- Easy configuration via NFC and Bluetooth
- Management and OTA upgrade via the Milesight Development Platform
Radar Technology for Tailored Applications
Aside from its extensive measurement distance, radar technology is also capable of measuring through objects, including plastics, and plants, and are less sensitive to snow, dirt, dust, steam and more, making it suitable for a wider range of applications.
