The LDRR04 80GHz FMCW radar level sensor is a professional non-contact water level sensor built for hydrological monitoring. It delivers reliable, high-precision data for rivers, lakes, reservoirs, flood early warning, and sewage pipe networks.
This compact radar uses 80GHz frequency with 4GHz bandwidth, offering a 0.1–40m measuring range, ±3mm accuracy, and 1mm resolution. It provides fast response with only 100ms startup time, ideal for real-time hydrological data collection.
With low power consumption (20mA@12V) and a wide voltage input of 9–24V DC, the LDRR04 is energy-efficient for long-term remote monitoring. It features an IP67 waterproof aviation connector, stable operation from -45°C to +85°C, and strong resistance to weather and interference.
Equipped with RS485 output (115200 baud rate) and dual support for ASCII and Modbus protocols, it integrates easily with telemetry systems for unattended monitoring. Its small size (Φ74×29.7mm) and 155g weight enable flexible installation in narrow spaces.
The non-contact design avoids water contact and maintenance, making it perfect for harsh environments. Whether for flood warning, urban drainage, or environmental monitoring, the LDRR04 80GHz radar level transmitter ensures stable and accurate water level measurement.
For robust non-contact water level monitoring, choose the LDRR04 80GHz radar level sensor.
