Home / Technical Articles / Danfoss – Max uptime for wind turbines

Powerful operating forces

Located on top of towers that can extend 80 to 110 meters into the air, wind turbines are subjected to powerful operating forces. And because wind turbines are difficult to access for maintenance and repair, reliable monitoring and control components, such as pressure and temperature sensors are vital for trouble-free operation.

And because they’re a critical link between control system fluids and components, choosing accurate, long-lasting pressure transmitters and temperature sensors is a must. Based on decades of experience with wind farms globally, Danfoss’ range of pressure transmitters and temperature sensors are ideal for demanding wind turbine applications.

Trouble-free and safe operation

Monitoring and controlling hydraulic pressure and temperature in wind turbine equipment and subsystems is a complex process; at start-up, pressure rises and at shutdown it’s released, and for lubrication and rotation functions, maintaining a minimum pressure level is crucial. To ensure smooth and safe operation, the temperatures of the hydraulic unit, generator, drive shaft, gearbox, oil braking and cooling systems have to be accurately monitored and controlled.

That’s where Danfoss comes in.

TempSensor_MBT5310Pressure and temperature signals are used by controllers to adjust valves, pumps and other equipment to maintain stable operation and, increasingly, to control safety functions. Designed to handle over-pressure and pressure spikes, liquid cavitations, dirt contamination, intense operating cycles, and extreme temperatures, Danfoss pressure transmitters and temperature sensors have been keeping wind turbines rotating, and safe, for decades.

Two industry favorites are the MBS 3000 pressure transmitter and the MBT 5310 temperature sensor. Fitted with a pulse snubber, the MBS 3000 can withstand water hammer, liquid cavitation and pressure peaks.

Designed to handle the heavy vibrations in wind turbines, the MBT 5310 features a spring-loaded sensor to ensure close and reliable contact – furthermore it can withstand temperatures up to 200°C.
