• Wind speed and direction, U-V Cartesian components of wind speed.
• Wind Gust (only in version with RS485 MODBUS-RTU output).

The average of wind speed and direction over a period configurable up to 10 minutes is calculated.

Two versions are available:

• HD53LS.A: with two analog outputs (one for wind speed and one for wind direction), factory configurable among 4…20 mA (standard), 0…1 V, 0…5 V, 0…10 V (to be specified when ordering).
• HD53LS.S: with RS485 MODBUS-RTU output.

Advantages of the HD53LS series:

• The absence of moving parts minimizes maintenance.
• High sensitivity for detecting very low speeds, which are not detectable by traditional methods.
• Fast and easy installation (on ∅ 40 mm mast, optional tripod available).
• The low power of the instrument allows installation in remote sites, with power from solar panel and battery.
• The version with RS485 MODBUS-RTU output allows instrument networking.

Available in different combinations for the measurement of:

• Wind speed (up to 85 m/s)
• Wind direction
• Cartesian U-V components of wind speed
• Wind Gust
• relative humidity and temperature (optional)
• global solar radiation (optional)
• atmospheric pressure (optional).

All combination options are also available with heating.

For particularly harsh environments, the HD51.3DR-AL model is also available for measurement of wind speed (up to 80 m/s) and wind direction, Cartesian U-V components, Wind Gust and atmospheric pressure (optional – model HD51.3D4R-AL).

This model is equipped with an upgraded heater, for quick defrosting, and an anodised aluminium alloy case with anti-corrosion coating that makes it possible to use 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 models have RS232, RS485 and RS422 serial outputs. NMEA, MODBUS-RTU and proprietary ASCII communication protocols. Two analogue outputs for wind speed and wind direction, factory configurable as 4÷20 mA (standard), 0…1 V, 0…5 V or 0…10 V.

Operating temperature -40…+70 °C. Instrument power supply 12…30 Vdc. Heater power supply 24 Vdc.

• Wind speed and direction, U-V Cartesian components of wind speed
• Wind Gust – Measurement available only with MODBUS-RTU and SDI-12 protocols
• Relative Humidity and Temperature (optional),
• Global Solar Radiation (optional)
• Barometric pressure (optional)
• Rainfall (optional)

The “Rainfall” and “Global solar radiation” options are alternatives (they can not be both present in the same instrument).

All models are equipped with a magnetic compass.

The avarage of wind speed and direction over a period configurable up to 10 mins is calculated.

RS232, RS485, RS422 and SDI-12 serial interfaces are available with NMEA, MODBUS-RTU and SDI-12 communication protocols. All versions have two analog outputs, both for wind speed and for direction, factory configurable among 4÷20mA (standard), 0÷1V, 0÷5V, 0÷10V (to be specified when ordering).

Advantages:

• The absence of moving parts minimizes maintenance;
• High sensitivity for detecting very low speeds, which are not detectable by traditional methods;
• The low power of the instrument allows installation in remote sites, with power from solar panel and battery;
• The heating option ‘R’ prevents the accumulation of snow and ice from forming, allowing accurate measurements in all environmental conditions;
• Fast and easy installation, alignment facilitated by built-in compass;
• The available measurement options join together in one single, compact and lightweight instrument, the main variables of interest in weather stations;
• MODBUS-RTU output allows instrument networking.
