The WD-CL Wind Vane is a highly responsive and versatile wind vane. The vane body is made from stainless steel and anodised aluminium. Stainless steel shafts, bearings and fittings are used throughout. A precision potentiometer is coupled to the vane shaft to provide an analogue output proportional to the wind direction. A counterweight provides precision balancing of the tail assembly on the shaft.
The Wind Direction Vane can be supplied with a Potentiometer (10kohms) or 4 to 20mA Output.
4 to 20mA output is:
4mA at 0 deg North
12mA at 180deg South
20mA at 360 deg North
