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.

Category: Wind Sensors

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.
