The invention relates to a method for the establishment of a signal which is indicative of the pressure-condition of a machine foot (1), as a fixed surface of a rubber-elastic body (5), where a load of the machine foot (1) is transferred from a cap (4) to a substrate (31) through the rubber-elastic body (5), which is pressurised by the increasing load, such that the distance between a free upper surface part (5.1) of the rubber-elastic body (5) and an immobile part (14.1) is determined by an electro-mechanical transducer (6) establishing an electrical signal corresponding to the distance which is used as the measurement for the rubber-elastic body's pressure-condition and thus the machine foot's load.
