Measurement of wind speed and wind direction. It can be combined with RH, temperature, pressure and radiation.

The instruments of the series HD52.3D… are 2 axes ultrasonic static anemometers for measuring:

• 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, code ‘17’),
• Global Solar Radiation (optional, code ‘P’),
• Barometric pressure (optional, code ‘4’).

All models are equipped with 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 analogical 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). Optionally available, (ACCREDIA) ILAC-MRA

traceable factory calibration.

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 (on 40mm diameter pole, optional installation kit HD2004.20), 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.
