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),
  • 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.
