In the wind power industry, the current domestic pitch system mainly adopts the electric pitch method, but in Europe, many major host manufacturers use the hydraulic pitch method. From a technical point of view, if the oil leakage problem can be solved, the hydraulic pitch will be more competitive in terms of system performance, reliability and overall cost.

Developed specifically for hydraulic pitch systems for wind turbines, the BTL micropulse displacement sensor from Balluff is installed in the hydraulic cylinders of the hydraulic pitch system and measures the displacement of the piston rod by detecting the movement position of the magnetic ring, thus monitoring the pitch angle of the blades.

According to the operation of the current unit, the control system calculates the optimal pitch angle value through a certain algorithm, and transmits the signal to the hydraulic pitch system. The hydraulic system drives the hydraulic cylinder according to the control command, and realizes the precise control of the pitch angle through the feedback signal of BTL, which ensures the safe and reliable operation of the unit while maximizing the power generation of the wind turbine.

In addition, because BTL uses magnetostriction, a non-contact measurement method, the maintenance costs of the equipment are reduced and the service life of the unit is greatly extended.

What is a balluff photoelectric sensor What is a balluff photoelectric sensor

Photoelectric sensors are sensors that use optoelectronic components as detection elements. It first converts the measured change into a change in the optical signal, and then further converts the optical signal into an electrical signal with the help of an optoelectronic component. Photoelectric sensors are generally composed of three parts: light source, optical path and optoelectronic components.
