2 AXES ULTRASONIC ANEMOMETER
2 axes ultrasonic Anemometers series HD 52.3D….
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,
Relative Humidity and Temperature (option, code “17”),
Diffuse Solar Radiation (option, code “P”),
Barometric pressure (option, code “4”).
All models are equipped with compass.
RS232, RS485 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).
The heater option prevents the accumulation of snow and ice from forming, allowing
accurate measurements in all environmental conditions.
Optionally available, ILAC-MRA (ACCREDIA) 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.
