HollySys AR2000 Radar Level Gauge
76–81 GHz FMCW radar level instrument for liquids and solids, with measuring range up to 120 m.
Product code: AR2000
Brand: Hollysys
Product Overview
The HollySys AR2000 uses 76–81 GHz FMCW radar for non-contact level measurement of liquids and solids. Its narrow beam supports vessels and silos with complex internals, while Bluetooth assists commissioning and device checks. Best supported accuracy can reach ±1 mm in suitable configurations and installation conditions; actual performance is application-dependent.

Key Features
- Bluetooth supports field configuration, commissioning, and diagnostic checks.
- A 3° or 8° beam helps reduce reflections from vessel and silo internals.
- Explosion-proof or intrinsically safe versions are available for hazardous areas.
- Verify mounting position, dead zone, obstructions, material surface, and dielectric constant; ±1 mm accuracy does not apply to every configuration.
