Wind Monitor

　　Model 05103

　　The Wind Monitor is a high performance wind sensor. Rugged, corrosion-resistant construction makes it ideal for a wide range of wind measuring applications.

　　The wind speed sensor is a four blade helicoid propeller. Propeller rotation produces an AC sine wave voltage signal. The wind direction sensor is a rugged yet lightweight vane. Vane angle is sensed by a precision potentiometer. Constructed of UV stabilized plastic with stainless steel and anodized aluminum fittings, the sensor mounts on standard 1 inch pipe. Model 05103V offers calibrated 0-5 VDC outputs, Model 05103L provides a calibrated 4-20 mA current signal for each channel.
