200P Wind Direction Sensor
Services Available


NRG's 200P wind direction vane is commonly used in wind prospecting applications. The thermoplastic and stainless steel components resist corrosion and contribute to a high strength-to-weight ratio. The vane is connected to a precision conductive plastic potentiometer located in the main body. An analog voltage output directly proportional to the wind direction is produced when a constant DC excitation voltage is applied to the potentiometer. A rubber terminal boot is included.

Additional Compatibility Information

Data Logger Considerations

The Wind Vane requires one single-ended channel and access to an excitation channel (the excitation channel can be shared with other high impedance sensors).


The wind vane is measured by the BrHalf Instruction in CRBasic and by Instruction 4 (Excite-Delay-SE) in Edlog. The measurements are typically processed for output with the Wind Vector Instruction (not present in the CR500 or CR9000).
