Safe drive monitoring with speed monitors and encoders.

The high system availability is especially crucial in wind turbines for the degree of efficiency and thus for an efficient production of energy. Sensors for safe drive monitoring are used to prevent damage and expensive downtime. The required safety requirements demand an optimal interplay between the safety sensors and the safety monitoring modules. Kübler offers a complete package for this purpose, consisting of certified encoders up to SIL3/PLe and small safety control systems.

Detection of excessive speeds with a safe overall system


The combination between speed monitor and certified encoders up to SIL3/PLe is the optimal solution for safe drive monitoring and thus for the early detection of excessive speeds. The encoder with SinCos signals, integrated in the slip ring, stands for a reliable speed detection of the rotor shaft.

Detection of excessive speeds with two incremental encoders


Alternatively, it is possible to install two encoders at different measurement points in the drive train to ensure a safe drive monitoring. In addition to the speed monitoring, the difference between the rotor and generator shaft is also optimally monitored for slip or gear break.
