INTRODUCTION
The instruments of the series
HD52.3D… are 2-axes ultrasonic static anemometers for the
measurement of:
•
Wind speed and direction, U-V Cartesian components of wind speed,
•
Relative Humidity and temperature (
optional
),
•
Global solar radiation (
optional
),
•
Barometric pressure (
optional
).
The available measurement options combine in a single instrument the main quantities of me-
teorological interest, making the instrument like a compact and light meteorological station.
All models are equipped with a magnetic compass.
Wind speed and direction are determined by measuring the transit time of ultrasonic pulses
between two pairs of ultrasonic transducers.
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, for wind speed and direction, which are factory-
configurable within 4÷20
mA (standard), 0÷1
V, 0÷5
V or 0÷10
V (
to be specified when or-
dering
).
The
heater
option prevents the accumulation of snow and ice formation, allowing precise
measurements in all environmental conditions.
Mounting on
∅
40
mm mast. The electric connection is performed through a M23 19-pole con-
nector situated on the bottom of the instrument.
The low power consumption of the instrument allows installation in remote sites, with power
supplied by photovoltaic panel and backup battery.
The absence of moving parts minimizes the instrument maintenance.
