Abstract: A device for monitoring and diagnosis of the state of a machine, machine component or system, with a housing (4), with a measured value detection unit (5) for detecting measured values supplied by at least one sensor (6) which is connected to the machine, machine component, or system, with a communications unit (7) for reading in process or operating data of the machine, machine component, or system, with an evaluation unit (8), which determines at least one value which characterizes the state of a machine (2), machine component (3), or system based on measured values delivered by the measured value detection unit (5) and process and operating data which have been read in by the communications unit (7), with a storage unit (9), with a communications unit (7) for outputting measured values, process or operating data and/or values computed by the evaluation unit (8), and with a display (10).

Abstract: A vibration sensor (1) for monitoring the state of rotating components or bearings, includes a housing (2), a sensor element (3), evaluation electronics (4), and at least one interface (5, 6). With the vibration sensor (1), reliable monitoring of the state of rotating components and bearings can be done easily and economically, and in addition the vibration sensor can be easily operated. The evaluation electronics (4) has an analog-to-digital converter (7), and a signal conditioning device (8) having a plurality of signals, which have been acquired by the sensor element (3), and which are converted into a state value using signal analysis and a diagnosis algorithm.
