 2100
Skyvane
Description
The Model 2100 Skyvane is a heavyduty wind speed and direction sensor designed
for installation in severe environments. It combines the features of a rugged
instrument with response characteristics similar to those of some lightweight
cup and vane systems. The Skyvane has a threshold of 2 mph and it will withstand
and accurately measure winds up to 200 mph, for limited durations. It is constructed
completely of corrosion-resistant materials, and the entire body assembly
is balanced to allow use on ships and ocean buoys.
Wind speed is measured by a 4-blade propeller coupled to one of three transducers
– a high frequency tachometer, an AC generator, or a DC generator. The
balanced propeller is fabricated from a special high impact plastic for maximum
sensitivity and strength.
Models
Model 2100 with the HF tachometer transducer is recommended for applications
where greatest responsiveness is required because this measuring system is
virtually frictionless. It consists of a slotted disc rotating between an
oscillator and a receiver; the output is a series of square waves with a frequency
proportional to wind speed.
Features
A counterbalanced tail monitors wind direction. Aerodynamic design assures
excellent alignment with the wind. The wind direction transducer may be either
a conductive plastic potentiometer or a synchro. The 5K-ohm potentiometer
has a range of 0° to 360°; electronic switching in the signal conditioning
module provides an optional range of 0° to 540°. Potentiometer linearity
is 0.5%. The synchro allows continuous indication with no discontinuity at
north. It operates on 115 VAC input power provided by the recording or indicating
device, which may utilize either 115 or 230 VAC.
Mounting
A mast adapter (Model 21101) may be used to mount the Skyvane to a 1.5-inch
(38 mm) O.D. mast.
