Wind energy offers an environmental friendly fuel alternative to fossil fuel-generated electricity. Because of the remote location of many windmills, sensors serve as critical components in their operation, maintenance and safety. Pressure sensors monitor yaw brake, lubrication oil, cooling circuit pressure, and level in gear boxes. Differential pressure sensors monitor filter conditions. As a hydraulic filter becomes clogged, the output signal increases, notifying the controller to replace the filter. As windmills are located in deserts, coastal areas and mountain tops; operating temperatures can range from -50 to 60°C. In addition, windmills are subject to salt, mist and fog, a leading form of corrosion. Instrumentation used to monitor the operating conditions for the windmill, therefore, needs to survive in severe conditions while offering reliability and trouble-free service.
