The SLDL5390 3D Radar Level Meter is a high-performance industrial sensing device based on advanced millimeter‑wave MIMO and beamforming technologies. Using FMCW (Frequency Modulated Continuous Wave) radar technology and radar beam scanning, this 3D level meter accurately detects distance, speed, azimuth and material height to build real‑world 3D point cloud models. With centimeter‑level precision and strong environmental penetration, the SLDL5390 3D Radar Level Meter operates stably 24/7 without being affected by dust, rain, fog, light, high temperature or corrosion. As a core intelligent sensor for industrial digitalization, the SLDL5390 3D Radar Level Meter provides reliable non‑contact measurement for inventory management, safety monitoring, robot navigation and intelligent traffic systems, laying a precise data foundation for smart decision‑making and efficiency improvement.
The SLDL5390 3D Radar Level Meter adopts high‑frequency 120–140GHz FMCW radar level measurement technology and beam scanning solution to realize multi‑point scanning and 3D imaging of bulk materials. It can be easily installed on various silos and bins, scanning internal materials through electromagnetic beam projection. The scanning data is transmitted to a computer or control system via RS485, and processed by professional imaging algorithms to reconstruct a 3D visualization model of material distribution.
The SLDL5390 3D Radar Level Meter supports dual‑mode operation: 3D imaging visualization mode and embedded direct data output mode. In visualization mode, it displays the highest/lowest material level, average level, volume and weight in real time. In direct output mode, the built‑in software automatically calculates key parameters and sends them to PLC, DCS or automation systems. This dual‑mode design makes the SLDL5390 3D Radar Level Meter flexible for inventory monitoring, process control and automated management in various industrial scenarios.
The SLDL5390 3D Radar Level Meter provides outstanding performance for harsh industrial environments:
• High‑frequency 120–140GHz radar with narrow beam and strong penetration
• 3D point cloud imaging and real‑time material distribution visualization
• Centimeter‑level measurement accuracy and volume error ≤3%
• Strong resistance to dust, steam, high temperature, corrosion and fog
• Non‑contact measurement, no wear, low maintenance and long service life
• Dual‑mode operation: 3D imaging and direct parameter output
• Multiple signal outputs: RS485, 4–20mA, Bluetooth
• IP66 industrial protection grade and wide temperature range from -40°C to +70°C
• Flexible scanning cycle from 1 to 30 seconds to meet different needs
These features make the SLDL5390 3D Radar Level Meter a top choice for reliable silo level and volume measurement.
