In addition to being rugged, AST pressure sensors operate over wide ranges of temperature and environments, from deserts to coastal plains.
Because of the remote location of many wind turbines, 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 clogs, its output signal increases, notifying the controller to replace the filter.
Wind turbines are located in deserts, coastal areas, and mountain tops, so operating temperatures can range from -50 to 60°C. In addition, wind turbines are subject to salt, mist, and fog. All can produce corrosion. Instrumentation that monitors the operating conditions for the wind turbine must survive severe conditions while providing reliability and trouble-free service.
In addition to being rugged, AST pressure sensors operate over wide ranges of temperature and environments, from deserts to coastal plains. Several sensors are said to be well suited to wind turbine applications. For example:
- AST 4000 pressure sensors offers high proof and burst ratings with excellent EMC protection
- AST5400 pressure sensors offer filter condition monitoring with linear and accurate readings.
- AST20HA pressure sensors offer pressure and temperature readings from one device, reducing process penetrations in the hydraulic system.
- AST4510 pressure sensors measure the level of oil in a reservoir while offering temperature output as an option. Maintaining and monitoring the level of oil is critical to maintain smooth supply of power from the wind turbine.
