MONITORING DEVICE FOR ROTOR UNIT

摘要

In a method for monitoring a rotor unit, the acquired data are converted, directly after acquisition and in the area of their location of acquisition, to a load profile or a load change profile and stored. In a device (8) for monitoring a rotor unit, a speed sensor (10) is coupled to a preferably programmable microcontroller (14) and at the same time to a voltage conditioning unit (16) via a signal processing unit (12). The speed sensor (10) and the voltage conditioning unit (16) together produce a voltage supply (18) integrated into the device (8), the device (8) being permanently operated therewith without an external voltage source. The integrated voltage supply (18) is linked to a voltage control (20) that ensures that the minimum possible operating voltage is invariably applied to the microcontroller (14) and to a non-volatile memory (22) linked to the microcontroller (14).
