Measuring the bearing gap in wind turbines

Targetted monitoring to predict failures of components and machines is getting increasingly popular in various industries. In this case, modern sensor technology helps in reducing maintenance and service costs by providing real-time monitoring facilities during the production process. In wind turbines, there are two main bearings in which rotor shaft runs. A consistent monitoring of bearing gap between the bearing surface and the drive shaft is one of the high priority tasks while installing a wind mill and failing to do so may result in rapid wear and bearing damage.

The inductive eddyNCDT 3005 sensors by Bestech Australia are capable of measuring upto 6 mm and provide accurate measurements of bear gap to prevent direct contact between the bearing surface and the shaft. These sensors are highly suitable for such applications involving typical oil pressures reaching upto 1 to 2 bar in the bearing. The eddyNCDT 3005 inductive measurement system is used to analyse and optimize the maintenance intervals of wind turbines and ideal for high volume applications for condition monitoring.
