A vibration pick-up unit (68) having a housing (66), in which at least one vibration sensor (76) and to a signal output of the vibration sensor (76) connected to the digitally operating signal processing circuit (88) are disposed, which with a digital interface (98) for outputting of from the signals of the vibration sensor (76) derived from state information of a machine element is connected. Besides within the housing (66), a purely analog operating, from the digitally operating signal processing circuit (88) independent signal processing circuit (90) is additionally arranged with is an analog interface (106, 106 ') for outputting the signals from the vibration sensor (76) derived warning signals in the event of detection of a foreign body together. |
