Ultrasonic Anemometer

It is a two-axis static ultrasonic anemometer used for accurate measurements of Wind Speed and Direction in all environmental conditions. It is Capable of measuring wind speed up to 85 m/s without giving up.

Heating option is available, for quick defrosting. A model with anodized aluminum alloy case with anti-corrosion coating is available. This feature makes it possible to be used the instrument even in particularly aggressive environments. The anemometer meets the requirements of MIL-STD-810G Method 509.6 (salt spray corrosion test). High immunity to electromagnetic interference makes it suitable for measurements in electrically noisy environments.

All measured meteorological data are transferred to dataloggers and
receiver units via a 2-wire RS485 bus with Modbus RTU protocol. This sensor is also equipped with two analog outputs for wind speed and direction, factory-configurable within 4-20 mA (standard), 0…1 V, 0…5 V or 0…10 V (to be specified when ordering)

All sensors are factory-calibrated and do not require additional interventions of the user.
