Wind energy plays a significant role in the generation of renewable energy. Wind turbines operate in the sea, nearshore and on land in all climate zones around the world, and they are often exposed to extreme environmental conditions such as salt water or temperature fluctuations. For the operators of wind turbines, it is extremely important to ensure the long-term normal operation of the machine, as maintenance or replacement of components is very difficult and costly. Zhongwei Supply Chain has a series of specialized products for wind turbine applications, including position sensors, process sensors and diagnostic systems. For instance, inductive proximity switches with high electromagnetic interference resistance and a wide temperature range, when used in combination with safety speed monitors, can monitor the speed of generators. Pressure, liquid level and temperature sensors on the hydraulic power unit and central lubrication system can ensure the reliability of medium supply. The oil moisture sensor and particle monitor can monitor the quality of the engine oil and lubricant used. To prevent the rotor from rotating unexpectedly, a dedicated rotor lock sensor can signal whether the rotor has been locked during maintenance.
