The Classic #40H anemometer is an unheated three-cup anemometer designed specifically for turbine control applications in non-icing conditions. The Classic #40H provides high precision wind speed measurements for accurate turbine control.
The Classic #40H is based on the #40C anemometer, the industry standard anemometer used worldwide; however, the #40H features a Hall Effect switch that induces a high-level square wave voltage signal with a frequency proportional to wind speed. This signal is easy to interface with a wide range of turbine controllers, programmable logic controllers, and data loggers. A 5-26 VDC excitation voltage with 5 mA of current is required.
The Classic #40 anemometer has recorded wind speeds of 96 m/s (214 mph), and their low moment of inertia and unique bearings permit very rapid response to gusts and lulls. Because of their output linearity, these sensors are ideal for use with various data retrieval systems.
The construction of the Classic #40H consists of rugged Lexan cups molded in one piece for repeatable performance.
A PVC terminal boot is included.
