Pro-Range PR-R2000 80GHz High Accuracy Radar Level Sensor (0-10m Range) - RS485 Modbus + 4-20mA Output, IP67, 1m Cable

The RS485 Modbus RTU output provides digital communication, allowing multiple sensors to be connected on a single bus for networked data acquisition and advanced configuration via software. The 3-wire 4-20mA analog output delivers a simple, continuous current signal proportional to the level, which is directly compatible with most PLC analog input modules and legacy control systems for straightforward integration.

No, the PR-R2000 utilizes advanced proprietary algorithms that typically eliminate the need for on-site calibration after physical installation. Initial configuration, such as setting the measuring range and output scaling, is performed via the provided PC software. The sensor's high-frequency FMCW technology and stable electronics ensure consistent accuracy without routine recalibration.

While 80GHz radar can penetrate certain non-metallic materials, performance depends on material thickness and type. For optimal accuracy and reliability, it is recommended to install the sensor with a direct, unobstructed view of the liquid surface. Measurement through sight glasses is possible but may introduce minor error and should be validated during commissioning. Consult the datasheet for specific guidance.

The integrated cable is 1 meter. For the RS485 Modbus connection, you can extend the communication line up to 1200 meters with proper shielded cable and termination. For the 4-20mA analog loop, the maximum distance depends on loop voltage and wire resistance; using 24V DC supply and 18 AWG wire, distances over 500 meters are typically achievable. Always use shielded, industrial-grade cable for extensions.
