Vayu Anemometers
Reliable, sturdy and precise aluminium anemometer for measuring wind speed and direction. Designed for a wide range of industrial applications.
Features
- They consist of a rotor featuring a removable hat for the mechanical fixing of impact resistant nylon cups: rotating on ball bearings, they activate a cogwheel which, by means of a optical transducer (photodiode), generates a 12 pulses/revolution frequency signal.
- For measuring a max. speed of 200 Km/h, equal to 55 meter per second. They are also suitable to be adjusted for lower full scale.
- IP protection degree: VAYU are classified IP 65 / IP 66.
- Extreme temperature resistance: from -20°C to +85°C, from -40°C to +85°C (versions with heater).
- All materials and components used are wear resistant and guarantee protection of the unit against water and dust: the body of the rotor is made of anodized alluminium or electropolished stainless steel AISI 316, the head rotates on double ball bearings and the cups (Ø 30 mm) are made of impact resistant nylon, protected against UV rays, low-temperature (max. -40°C) and hail, and easily interchangeable.
Options
- Featuring frequency pulse output, 0-5 Vdc / 0-10 Vdc / 1-5 Vdc / 2-10 Vdc analogue voltage output or 0-20 mA /4-20 mA current output.
- Ready to be connected, through the different outputs available depending on the model, directly to PLC and / or market electronic board and tachometers.
- Versions with 24 Vdc anti-icing heater available on request.
- Featuring M12 connector - 5 screw pins and a stainless steel fixing bracket.
- Wind tunnel tested and supplied with a calibration certificate. Periodic check of the product adjustment and calibration available on request.
Certifications
- CE marking.
