Occasionally, you have to just switch off. But when is the right point in time? In the case of a wind turbine that has to be powered down in the event of danger, the mast vibration phase - zero-axis crossing or maximum - in which the turbine is stopped to prevent the mast from receiving an 'additional kick' that causes damage may be crucial. This point can be set precisely with the new SIL2 vibration sensor NVA115 from TWK.

Aiming high with safety

The higher the more wobbly - this should never be the case, of course. Quite the opposite: the standard of safety should not suffer from aiming high. Cranes and mobile cranes as well as lifting platforms must therefore be equipped with safety sensor systems to always guarantee stability and operating safety.
