011 E-Class One Wind Sensor

Applications for horizontal wind speed measurement, such as power performance assessment in the wind energy industry, require a combination of high accuracy and linearity over the wind speed range of interest. The 011 E-Class One Wind Sensor has been specially designed to meet this challenge through modern engineering, materials choice, and field-proven performance.

Operation

The 011 E-Class One Wind Sensor is verstible, designed to meet anemometry performance criteria for “Class 1” in accordance with IEC 61400-12-1. With optimized dynamic response the 011 E-Class provides accurate horizontal wind speed measurement in flat and complex terrain environments and a high accuracy and linearity over the wind speed range of interest that includes wind turbine generator operation and wind gust measurement. Based upon legacy 010C platform characterized by many years of field-proven performance at thousands of installations worldwide the 011 E-Class is very reliable.

Construction

The 011 E-Class One Wind Sensor was a patent pending innovative asymmetrical aerodynamic cup set design for superb cosine response and a high strength polymer cup design reduces stress points for long-lasting performance.
