Bestech develops new compact meteorological transducer

Bestech Australia announces the release of a new compact meteorological
transducer designed for professional weather station applications.

Featuring digital sensors for measuring wind, precipitation, air
temperature, atmospheric humidity and atmospheric pressure, the new meteorological
transducers feature maintenance-free measuring procedures for wind and
precipitation, and forced-ventilated and radiation-protected housing.

The FMD760 digital meteorological transducer, with integrated signal processor
or A/D converter, can acquire more than 20 important measurable weather variables
in one device. Up to 10 measuring channels can be evaluated simultaneously via the
ALMEMO D7 plug.

The FMD760 digital meteorological transducer comes factory programmed
with the following variables: wind velocity (m/s), wind direction (¡),
precipitation quantity (mm), precipitation intensity (mm/h), air temperature
(¡C), relative atmospheric humidity (%RH), and barometric atmospheric pressure (hPa).
The meteorological transducer operates with current ALMEMO V7 devices,
including precision touch screen data logger ALMEMO 710 and professional
measuring instrument ALMEMO 202.

The meteorological transducer complies with all specifications laid down
by the World Meteorological Organization (WMO) and finds application in weather
services, water management, transport technology (roads, rail), agriculture, renewable
energy technology, and monitoring of air quality and atmospheric emissions.

The transducer can be fitted quickly and easily on a mast or pole, using
the supplied bracket.

Wind is measured by means of four ultrasonic sensors with wind velocity calculated
in m/s and wind direction in ¡.

Precipitation readings are acquired using the tried and tested radar
technology. A Doppler radar measures the velocity of individual drops of
rain/snow. Precipitation quantity (in mm) and precipitation intensity (in mm/h)
can be calculated on the basis of the correlation of drop size and drop
velocity while the type of precipitation (rain/snow) is determined on the basis
of the different velocity of descent.

Air temperature is measured (in ¡C) by means of a high-precision NTC
resistance sensor, and relative atmospheric humidity is measured (in % RH) by
means of a capacitive humidity sensor. These sensors are enclosed in a
forced-ventilated, radiation-protected housing in order to minimise external
influences from solar radiation or other conditions and ensure accurate measuring

Absolute atmospheric pressure is measured (in
hPa) by means of an integrated sensor.
