Wind Monitor-SE
09101-28
The Wind Monitor-SE combines the performance and durability
of the standard Wind Monitor with an optically encoded direction
transducer and serial data output capability.
The wind speed sensor is a four blade helicoid propeller that turns
a multipole magnet. Propeller rotation induces a variable frequency
signal in a stationary coil. Slip rings and brushes are not used.
The wind direction sensor is a durable molded vane. An
optical encoder measures vane angle, thereby eliminating the
characteristic deadband and wear of potentiometer transducers.
The encoder is an absolute type so direction output remains
accurate even if power is interrupted.
Raw transducer signals are processed by onboard electronics.
A variety of serial protocols or a conventional calibrated voltage
output may be selected with simple internal jumpers.
The Wind Monitor-SE is designed for superior environmental
resistance. Housing parts are UV stabilized thermoplastic. Fittings
are stainless steel and anodized aluminum. Precision grade
stainless steel ball bearings are used throughout. The instrument
mounts on standard 1 inch pipe.
