The invention relates to a method for the determination, in particular for contactless determination, of an operating state of a compressor () and/or a rotational speed of a compressor drive (), in particular of a variable-speed or fixed-speed compressor drive (), having the following method steps:

Method for the contactless determination of an operating state

The disclosure relates to a method for determination of an operating state of a compressor and/or a rotational speed of a compressor drive of the compressor comprising; measuring, over a time range, a magnetic field associated with one or more phases of an electrical power supply conductor supplying the compressor with electrical power; wherein the magnetic field is measured by a detection element to provide a representation of the magnetic field; determining a frequency spectrum of the representation of the magnetic field over the time range; and analyzing the frequency spectrum of the representation of the magnetic field over the time range to determine an operating state of the compressor and/or to determine a rotational speed of the compressor drive. The disclosure further relates to a device for carrying out the method, a compressor measuring system, and a computer-readable storage medium.
