Abstract
The Invention concerns a device, a system and a method for detecting misbehavior of a damper element (104) based on a change in vibration measured by means of at least one sensor (105). The device comprises a sensor (105) to measure the vibration experienced in the device. If the vibration meets a predefined threshold value, an indication of misbehavior of the damper element (104) is outputted. The system comprises multiple devices for measuring the vibration. If a threshold value is met In at least one of the devices, an indication is outputted to a central computing unit. The central computing unit is configured to detect the number of indications received and if only one indication is received, it can be concluded that a damper element (104) is broken and an alarm signal can be outputted. The method according to the invention describes the method steps of the solution.
