SKU: DL-HD52.3DT147-DEL-1-1 Category:

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.
