Combined wind speed and wind direction sensor
Combined wind speed and wind direction sensor. This sensor range includes, in a single apparatus, transducers for both wind speed and wind direction measurement. Its use simplifies installation requirements, other than being smaller, lighter and cheaper than the general 2-sensors kit. Accuracy and thresholds are anyway near to be comparable with a 2-sensors cup and vane kit alternatives. Different data output signals are available.
• Alternative signal outputs: (Hz+0-1 V), 0-5 V, 4-20 mA, RS485 Modbus;
• Wide power supply: 9-30 Vac/dc;
• Simple to install on pole 5 cm diameter;
• High demage threshold up to 75 m/s;
• Optional cable up to L.100 m In house;
• ISO17025 accreditate calibration laboratory.
