Micronor introduces yaw position sensor for wind turbines

Micronor’s MR200W series Yaw Position Transducers are engineered specifically for wind turbine applications, and monitor position, direction, speed and cable twist while giving feedback to the yaw directional motor drive and brake control system.

An MR200W series position transducer for wind turbines can be multifunctional and integrate any combination of: geared limit switches, rotary encoder, resolver or potentiometer. For increased accuracy and repeatability, the unit can be supplied with an external anti-backlash POM (polymer) pinion gear which optimises coupling to the wind turbine's large yaw bull gear, Micronor says.

The yaw drive is used to keep the rotor of the wind turbine facing into the wind as the wind direction changes.
