Speed and position acquisition in the pitch system
Optimise the energy yield of your wind turbines by aligning the rotor blades precisely. Acquire the blade position with our robust, high-resolution sensors. The magnetic measuring system is more than a match for extreme ambient temperatures, humidity, dirt, condensation and strong vibrations.
We recommend our absolute rotary encoders GEL 2037with integrated bearings and heavy-duty flange or target wheel adapter. The redundant measuring system with integrated electrically isolated resolver and 25-bit resolution is ideally suited for this application. The gear-based multiturn encoders acquire changes in the blade position safely and reliably. The benefit to you is that the battery-less sensors operate maintenance-free.
Do you have little available installation space in the pitch motor? Then why not use our much smaller incremental speed sensors GEL 248? They allow a target wheel connected to the motor shaft to be scanned contactlessly, which means they do not wear out and require no maintenance. By using two sensors on one target wheel, we can create a redundant system for you.
