Detailed Description
Advanced 3D Wind Field Analysis
As LSI LASTEM's flagship ultrasonic sensor, the DNB147 captures complex wind patterns with triaxial ultrasonic transducers. Measures azimuth (0–360°), elevation (±60°), gusts, and turbulence intensity—critical for wind turbine efficiency studies, pollutant dispersion modeling, and boundary-layer research.
All-in-One Meteorological Station
Beyond wind vectors, integrated Pt100 thermometers, capacitive humidity sensors, and piezoresistive barometers provide comprehensive microclimate data. The magnetic compass auto-corrects directional alignment, while 250ms response time detects microbursts and shear events missed by mechanical sensors.
Key Advantages
- Triaxial wind measurement: U/V/W vectors + sonic temperature
- ±1° directional accuracy with configurable 0.2 m/s threshold
- Integrated environmental sensors: temp, RH%, pressure
- Zero moving parts—immune to icing, corrosion, and wear
- Modbus-RTU protocol for SCADA/BMS integration

Usage Guidelines
Installation & Calibration
Mount vertically using DNB192 adapter. Ensure 10m clearance from obstacles. Use MG2272 12-pin connector with factory-supplied 10m cable. Compass auto-calibrates at startup—avoid magnetic interference.
Data Integration
Configure Modbus registers for: - Instantaneous U/V/W vectors - 3-second gust peaks - Sonic virtual temperature - Compensated pressure/RH% For ISO17025 calibration (SVACA2216), validate annually.
