Pitch control in wind power applications |
|
In modern wind turbines the pitch system is a vital part of the turbine as it not just helps the turbine to generate power but also serves as the security system in case of an accident or failure. The pitch system is therefore very often critical for the survival of the turbine in case of an emergency situation.
We offer 5 years of warranty on position sensors for wind power applications - this is your guaranty of a secure and reliable pitch systems.
The pitch system generally fulfill three functions
- Controls the pitch angle
- The fail safe function
- Feedback position of each blade

Oil level control with HBSO |
|
Oil level control sensors used in hydraulic pitch systems and in the hydraulic system in general.
HBSO switches are designed to detect oil and lubrication on all types of wind turbines and wind applications. Resists pressures up to 170 bar.
Applications in the turbines could be
- Watch/secure for oil flow
- Control of oil return from oil separators/filters
- Low oil alarm
HB Products also supplies switches used as level alarm in water and brine cooling systems in wind generators.
