Delta OHM Air and Wind Speed

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;
