　　Wind Monitor

　　Model 09101

　　The Wind Monitor-SE combines the performance and durability of our standard Wind Monitor with a unique optical encoder direction transducer and serial output.

　　The wind speed sensor is a four blade helicoid propeller. Propeller rotation induces a variable frequency signal in a stationary coil. The raw signal is converted to a digital serial output by the onboard microprocessor circuit. The wind direction sensor is a durable molded vane. The absolute encoder retains direction orientation even if power is interrupted. Serial output or voltage output signal is selected simply by moving an internal jumper. Housing parts are UV stabilized thermoplastic. Fittings are stainless steel and anodized aluminum. The instrument mounts on standard 1 inch pipe.
