Reliable confirmation of rotor lock and pitch cylinder status
During maintenance procedures, for personnel and equipment safety, the wind turbine shaft must remain at a standstill with the rotor blades feathered out of the wind. Balluff's hydraulic pressure-rated inductive sensors report the extended/retracted end-of-stroke position of rotor locking cylinders and pitch control cylinders.
- Pressure rated to 500 bar
- Installed directly into the pressurized areas of hydraulic cylinders to monitor piston position
- Stainless steel housings resist corrosion
- Analog version for soft stop upon reaching end-of-stroke
