Overview
SENSOR WIND SPEED NRG ICEFREE3A, 26Ft (8M)
The ICEFREE3A anemometer is an electrically heated wind-speed sensor, designed for ice-prone sites. The sensor provides an electrical output signal with frequency directly proportional to wind speed.
The ICEFREE3A is manufactured by Renewable NRG Systems and has an 8 m (26 ft) cable.
Technical Description
The ICEFREE3A monitors wind speed using a three-cup anemometer. Rotation of the cup wheel produces a sine-wave that is directly proportional to wind speed. The frequency of the sine wave is measured by the data logger pulse count channel, then converted to engineering units (mph, m s-1, knots).
