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.
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 – furthermore it can withstand temperatures up to 200°C.
