The NRG Systems Classic #20H turbine control vane is an unheated yaw control vane designed specifically for turbine control applications in moderate climates. The Classic #20H provides high precision for accurate yaw control to improve your wind turbine’s power performance.

The Classic #20H is based on the NRG Systems #200P wind direction vane, the industry-standard wind direction vane used worldwide. Recognized for its reliability and aerodynamic performance, this design features thermoplastic and stainless steel components which effectively resist corrosion and contribute to a high strength-to-weight ratio. Non-contact sensing leads to longer sensor life.

The Classic #20H turbine control vane features a 4-20 mA current loop signal which is compatible with some existing wind turbine controllers and easily integrates with a wide range of programmable logic controllers (PLCs) and data loggers. The 4-20 mA signal facilitates automatic detection of wiring faults or failures by the turbine controller to ensure high reliability.

A PVC terminal boot is included.
