Product Introduction of LRD701 / LRD702 Radar Level MeterLRD701 / LRD702

LRD701 and LRD702 are FMCW millimeter wave radar level meters manufactured by Winters Instruments. Adopting millimeter wave frequency band higher than Ku-band radar, they feature narrow 3° beam angle, strong penetration and high resolution, delivering non-contact, high-precision level measurement for complex working conditions.

Core Technical Specs

- Measuring range: 8m / 15m, measurement accuracy: ±3mm

- Output modes: 2-wire 4~20mA, 4-wire RS-485 Modbus-RTU

- Power supply: DC 24V; Protection grade: IP68

- Ambient working temperature: -20℃ ~ 70℃, storage temperature: -40℃ ~ 80℃

- Process connection: G1", G1 1/2", G2" thread; housing optional PP/PVDF/PTFE/PFA

Application Scope

Suitable for measuring media with dielectric constant over 2. It works well in dusty, smoky harsh environments for liquid and solid level detection in tanks, wells and silos. The matched mobile APP (RadarMe) supports Bluetooth parameter configuration and real-time data monitoring.

Key Advantages

Small beam angle avoids false echoes from tank walls, ladders and pipelines. It supports parameter backup & restore, adjustable damping time for stable output, and Modbus 485 communication for industrial system integration.
