motion sensors 4 wind turbinesFRABA’s OPTIPACT motion sensors measure velocity by calculating the rate at which an image of a moving surface travels across an optical sensor. With no contact between the sensor and the moving object, dust or surface contaminates won’t cause problems. These sensors provide a suitable way of determining rotor speed in wind turbines: just measure the velocity with which part of the rotor (e.g. nose cone or shaft) moves past a point on the body of the turbine. OPTIPACT motion sensors are compact, robust and appropriate for primary or backup rotor speed regulation.
