The DNA310.1 wind vane delivers precise 0–360° direction monitoring with a 0–1V analog output. Featuring an anodized aluminum body, magnetic encoder, and IP66 protection, it operates at 0.5W power across -40°C to 80°C. Ideal for meteorological networks, wind farms, and third-party integration.
Overview
The DNA310.1 wind vane delivers precise 0–360° direction monitoring with a 0–1V analog output. Featuring an anodized aluminum body, magnetic encoder, and IP66 protection, it operates at 0.5W power across -40°C to 80°C. Ideal for meteorological networks, wind farms, and third-party integration.
Detailed Description
High-Accuracy Wind Vector Analysis
Engineered for critical directional tracking, the DNA310.1 uses a magnetic encoder to achieve 2° accuracy even at low winds (0.15 m/s threshold). Its sealed bearing housing prevents dirt/water ingress, eliminating maintenance needs throughout the sensor's lifecycle.
Ruggedized for Extreme Environments
With anodized aluminum construction and IP66-rated components, this wind vane withstands marine corrosion, desert dust, and storm-force winds. Compliant with VDI3786 and ASTM 5366-96 standards, it delivers industry-leading damping (coefficient 0.21 @10 m/s) for stable readings in turbulent conditions.
Key Advantages
- 2° accuracy across full 360° range—superior to industry average
- Sealed bearing system: zero lifetime maintenance
- Low 0.5W power consumption for solar-powered stations
- 0–1V linear output for direct E-Log/Alpha-Log integration
- VDI/ASTM-compliant delay distance (1.2m @10 m/s)

Usage Guidelines
Installation & Integration
Mount vertically using DYA046 coupling bars for paired WS/WD setups. Use 7-pin IP65 connector with DWA5xxA cables (up to 100m). For E-Log/Alpha-Log data loggers, connect directly to analog input channels.
Optimization Tips
Position 10x obstacle height from interference sources. In coastal sites, rinse bearings annually with freshwater. For ISO9001 calibration (SVICA2304), recalibrate every 2 years.
