The 05103-45 Wind Monitor is designed for harsh alpine conditions. To discourage ice buildup, the sensor’s housing is black and covered with an ice-resistant coating. The 05103-45 has a smaller propeller diameter than the other wind monitor models, which minimizes vibration at high wind speeds. Wind speed is measured with a helicoid-shaped, four-blade propeller. Wind direction is sensed by the orientation of the sensor body, which is connected to a potentiometer.

Features

Sensor Cabling
The probe's cable is wired into a small junction box at the base of the sensor.
