Direction transducer and serial data output.
Overview
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.
The "-L" on a product model indicates that the cable length is specified at the time of order.

Detailed Description
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 2.54 cm (1 inch) pipe.

Compatibility
Mounting
The Wind Monitors can be attached to a CM202, CM204, or CM206 crossarm via a L17953 NU-RAIL fitting or CM220 Right Angle Mounting Bracket. Alternatively, the Wind Monitors can be attached to the top of our stainless-steel tripods via the CM216 Sensor Mounting Kit.
Datalogger Considerations
The 09101-L's propeller turns a mulipole magnet. Its wind vane uses an absolute type optical encoder. Raw transducer signals are processed onboard in order to supply a variety of serial outputs or an analog 0-5V output.
