The apparatus for monitoring appliances and machines having rotating components, particularly for monitoring compressors, vacuum pumps and other pumps, has a sensor, an evaluation electronics unit and an interface for the output of signals. The evaluation electronics unit has a microprocessor having three inputs for performing measurements in three different frequency ranges at different frequency resolutions, with the respective vibration intensities being averaged at a plurality of frequencies in line with the third-octave spectrum. The interface is a two-wire interface which is used to report different operating states using different DC values. |
