| The Model 09101 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 dead band 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 09101 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.
