Description : Three conial beaded edged cups 50 mm. In diameter, attached by arms to
a central boss drive a vertical spindle at a rotary speed proportional to the
wind velocity.
Aluminum, Brass and Stainless Steel are used throughout this instrument to
ensure freedom from corrosion and long working life. A conical shield protects
the spindle and bearing from the rain.
An Infra Red Transducer connected to the vertical shaft gives
pulses proportional to the number of rotations of the vertical shaft.
This signal is carried through interconnecting cable ( standard length 20
mtrs.) to the Transmitter unit.
4 - 20 mA OR 0 - 5 Volts Dc output proportional to the wind velocity is provided
which can be fed to any Data Logger or PLC.
