The 200P Wind Vane is one of the most widely used wind direction sensors in wind, solar, and meteorological applications worldwide.
#1904
Constructed of thermoplastic and stainless steel components, the 200P resists corrosion and features a high strength-to-weight ratio. The 200P is directly connected to a precision conductive plastic potentiometer located in the main body. When a constant DC excitation voltage is applied to the potentiometer, it produces an analog voltage output directly proportional to the wind direction.
The 200P includes a PVC terminal boot for additional protection from the elements.
