A method for early damage recognition of a machine, and program and control unit for executing the method are disclosed. The method is disclosed for early damage recognition, wherein a frequency-transformed signal, filtered of dominant excitations, is supplied to a comparative early damage recognition, and wherein, after the filtering, damage of the machine is recognized by comparing the signal to a comparison value.

Disclosed is an electronic operating data memory for a rotationally operating machine, with a transceiver device for the contactless transmitting and/or receiving of data, it being possible for operating data of the machine that are stored on the operating data memory to be read out and/or overwritten by means of a mobile terminal. The operating data include data that relate to the rotational operating principle of the machine and can be monitored and displayed by means of the mobile terminal.

A sensor arrangement for a hydraulic displacer unit includes a plurality of sensors which, at least in some sections, are positioned jointly in a sensor housing. The sensors are configured to be contacted via a common plug.

Sensor arrangement for a hydraulic displacer unit

The invention relates to an apparatus () and a method for the condition-dependent maintenance of hydrostatic displacement units (), in particular axial piston machines () operated as pumps or motors. Mounted on the hydrostatic displacement unit () are acceleration sensors () and/or contamination level sensors () which capture vibration data and/or contamination data of the hydrostatic displacement unit () and are connected to an evaluation unit () which temporarily stores the vibration data and/or contamination data. A communication unit () connected to the evaluation unit () retransmits said data.

Apparatus and method for the condition-dependent maintenance of hydrostatic displacement units

The invention relates to a device () for state monitoring in hydrostatic displacement units (), in particular in axial piston machines () operated as a pump or as a motor. The device () comprises an acquisition unit () with a multiplicity of sensors () which are attached to the hydrostatic displacement unit () and serve to acquire monitoring data () and operating data (), and an evaluating unit () which has a device () for analysing the monitoring data in the frequency range and a device () for analysing the monitoring data in the time range. A diagnostic unit () with an output unit () is connected to the evaluating unit ().
