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.
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. Monitoring and controlling hydraulic pressure and temperature in wind turbine equipment and subsystems is a complex process; at startup pressure rises and it’s released at shutdown, 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.
Pressure 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, and it can withstand temperatures up to 200°C.
