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.
