Method for establishing a signal indicative of the pressure-condition in the as contact-surface befitted rubber-elastic body of a machine foot, as well as machine foot with hydrostatic pressure sensor

A machine foot, comprising:

• an adjustable spacer having a first end configured to be coupled to a machine, and a second end configured to be coupled to a load distributer, wherein the load distributor comprises a load-carrying cap and a rubber-elastic body;
• and
• an electro-mechanical transducer having a mechanical part and an electrical part, and wherein the electro-mechanical transducer is embedded in the rubber-elastic body and arranged to provide an electrical signal for indication of the pressure-condition;
• wherein the load-carrying cap comprises an upper side having a central area and a lower side adjacent to the rubber-elastic body, wherein the central area on the upper side of the load-carrying cap is configured to receive an entire load from the spacer, and configured to transfer the load through to the entire lower side to the rubber-elastic body, wherein the rubber-elastic body is configured to transfer the load to a substrate;
• wherein the electro-mechanical transducer comprises a tubular sleeve having an immobile part disposed therein;
• wherein the mechanical part of the electro-mechanical transducer is designed to convert a given internal overpressure in the rubber-elastic body to a corresponding movement between a free surface of the rubber-elastic body and the immobile part of the electro-mechanical transducer;
• and
• wherein the electrical part of the electro-mechanical transducer is designed to deliver an electrical signal corresponding to the size of the distance between the free surface and the immobile part.
