The YOUNG Model 05108 Wind Monitor-HD measures horizontal wind speed and direction. This sensor has many of the same features as Model 05106, including long-lasting, corrosion resistant, ceramic bearings and a ¼ inch diameter propeller shaft. It features a high pitch propeller that will extend bearing longevity due to its lower rotation rate at like wind speeds. The direct output for wind speed is an AC sine wave and direction is a precision potentiometer. The sensor mounts on a standard 1-inch IPS pipe. A mounting orientation ring is included.
A separate Surge Protection Assembly, Model 19120, is available that doubles as both a junction box for cable termination and additional electrical transient surge protection. Separate signal conditioning devices are available to convert the sensor signals to 0-5 V (Model 05608C) or 4-20 mA (Model 05638C). All three of these devices are enclosed in weatherproof enclosures and come with mounting hardware (Model 19120 is not typically used in conjunction with either Model 05603C or 05631C).
