mechanical wind vane for use in wind industry


    ​The PV-1 was developed in response to customers in the field. Earlier technology too often fell short in its ability to accurately capture data in every direction and in cold, icy environments. With the PV-1, you get all the features you expect in an affordable, high-performance wind vane: simple construction, stable/smooth response to wind change and perfect balance.

    The PV-1 is a continuous-rotation potentiometric wind direction vane featuring stainless steel and thermoplastic construction for corrosion resistance. It is ideal for applications including wind resource assessment, meteorological studies, and environmental monitoring. The mechanical range is a full 360 degrees with continuous rotation, and the instrument is compatible with all Nomad wind data loggers from Second Wind and similar data logging devices.
