The accurate wind sensor uses the run-time differential method for determining the wind speed and wind direction. It provides output for instantaneous values, vector and scalar means, the maximum gust of wind and wind direction, the maximum/minimum values and the virtual temperature. Data output through serial or analogue interfaces provides compatibility of the Lufft Ventus for commercially available hydrometeorological dataloggers and PLC systems. An automatic heater ensures reliable operation even in harsh environmental conditions.

Parameters measured:
Wind speed, wind direction, virtual temperature, barometric pressure

Measurement technology:
Ultrasonic

Product highlights:
Wind detection with birdproof construction, maintenance-free measurement, suitable for extreme ambient conditions, ice-free operation, vibration and seawater resistant, compatible interfaces

Interfaces:
SDI-12, RS-485 with supported protocols Binary, ASCII, NMEA, Modbus & analogue output

Highlights:

• Measuring wind direction and speed insusceptibly to bird nesting thanks to roofed construction
• Built-in data pre-processing, universal interfaces and selectable output protocols – compatible with OTT-dataloggers, commercially available HydroMet dataloggers and PLS systems
• Maintenance-free operation – no moving parts that can wear out thanks to ultrasonic measuring method; no need for re-calibration
• Suitable for all climate zones; also for solar-powered automatic meteorological stations
• Integrated heater that can be switched on if there is danger of frost – guarantees ice-free operation in extremely low temperatures until -40 °C
• Vibration and seawater resistant – also applicable in coastal regions
• Successfully tested and certified in extreme ambient conditions (temperature, air humidity, electromagnetic compatibility, vibration, salt spray, and icing)
• Embedded algorithms that provides the wind speed and direction as actual and averaged values
• Wind gust calculation regarding WMO (Guide to Meteorological Instruments and Methods of Observation)

The robust and maintenance-free wind sensor is designed for professional meteorological applications in all climate zones. It delivers reliable data, even in extreme ambient conditions.
