Deepsss.....

Do you mean the pitch angle of the propeller on a wind turbine generator?

yea.... Its for wind turbine generator.. I want to know what is pitch angle and how can i measure that???? Thank u so much...

It is that angle relative to the "face" of the turbine blades. It is used to control the speed of the wind turbine
You can use a shaft angle encoder on the servo that is rotating the turbine blades, to measure the pitch angle ; and the pitch angle data will be available on the PLC that is used to control the wind turbine

hmm... thank u for yr reply...

Put your turbine blade on the floor with its shaft vertical. Measure the angle between the blade and the floor. For a "proper" blade it varies through out its length as the radial distance from the centre. If you want typical values try here :- 14' Homebrew Wind turbines
