The launch of HIKMICRO‘s LRG10 series marks a significant milestone in the 80GHz radar level measurement market, demonstrating the growing demand for high-frequency radar solutions in industrial and environmental monitoring. As a Chinese radar manufacturer with independent R&D and production capabilities, we are proud to introduce our own 80GHz ranging radar module — the LDRR05B — designed to deliver reliable, cost-effective performance for a wide range of level and distance measurement applications.
Product Overview
The LDRR05B is a compact 80GHz FMCW ranging radar module engineered for both solid and liquid measurement scenarios. Operating in the 77–81GHz frequency band, it penetrates fog, rain, and dust with ease, delivering stable, interference-resistant performance in challenging environments. Whether deployed in water conservancy projects, reservoir monitoring, tank level gauging, or sewage network management, the LDRR05B provides consistent, maintenance-free operation with exceptional power efficiency.
Key Technical Specifications
Measurement Performance – With a maximum ranging distance of 40 meters and an accuracy of ±5mm, the module meets the demanding requirements of industrial level monitoring. The 1mm resolution ensures fine-grained detection, while the 1‑second start‑up time allows for rapid deployment. The radar‘s wide ±40° beam width (-3dB) provides extensive coverage, and an optional external lens antenna can narrow the beam to ±3° for precise long‑distance targeting.
Ultra‑Low Power & Wide Voltage – Operating on 3.3–5V DC, the LDRR05B draws only 11mA typical, making it ideal for battery‑powered or solar‑powered remote installations. The wide voltage tolerance ensures compatibility with most industrial power systems.
Rugged Environment Adaptability – With a -45°C to +85°C operating range and a PTFE (polytetrafluoroethylene) lens that resists corrosion and high temperatures, the module performs reliably in harsh chemical, outdoor, and high‑humidity environments.
Compact Form Factor – At just 32mm in diameter, 1.2mm in height, and weighing only 23g, the LDRR05B is one of the most space‑efficient 80GHz radar modules available, easily integrating into integrated radar level gauges, material level indicators, and portable instruments.
Communication & Integration
The LDRR05B communicates via UART (default 115200 baud) with support for MODBUS and a proprietary protocol, simplifying connection to PLCs, data loggers, and IoT platforms. The TTL interface enables direct microcontroller integration, reducing development time and component costs.
Applications
The LDRR05B is ideally suited for:
-
Water Conservancy: River, lake, and reservoir water level monitoring
-
Liquid Level Measurement: Tank gauging in chemical, petrochemical, and food industries
-
Solid Level Monitoring: Silo and hopper material level detection in mining, agriculture, and construction
-
Environmental Monitoring: Sewage level tracking, stormwater management, and flood early warning systems
-
Integrated Instruments: OEM integration into radar level gauges and material level indicators
