Improved reliability
and lower cost thanks to rugged, light weight,
sea air and pollutant corrosion-resistant
construction
Construction of UV stabilized thermoplastic
with stainless steel and anodized aluminum
fittings
Injection-molded helicoid shape propeller
Propeller rotation produces AC sine
wave voltage signal with frequency directly
proportional to wind speed.
AC voltage signal induced in a centrally
mounted coil by a six pole magnet mounted
on propeller shaft.
Coil located on the nonrotating central
portion of the main mounting assembly,
eliminating the need for slip rings and
brushes
Assures good fidelity in varying wind
conditions
Vane position sensed by a precision
conductive plastic 10K ohm potentiometer
located in sealed chamber below wind speed
transducer coil.
Regulated excitation voltage applied
to potentiometer element produces an analog
DC voltage directly proportional to azimuth
angle.
Transducer coil and potentiometer leads
end in junction box on mounting post for
ease in making sensor cable connections.
• A 5 conductor cable is required
for power and sensor connections.
Stainless steel precision ball bearings
in propeller and vertical shaft
Orientation ring for maintaining wind
direction reference if instrument removed
for maintenance

Hints
Connect speed output to counter input
of 8200A or 8210 Recorder. Connect direction
output to analog input.
Note: you must use the
wind speed/wind direction sensor definition
in the Enable sensors menu in the 8200A/8210
setup. Failure to do so will provide incorrect
i.e. non vectored reading. Refer to chapter
6 and 7 of the 8200A/8210 Operations Manual
for setup information.
