Combined elevator vibration isolation and load measurement element

A combined elevator vibration isolation and load measurement element comprising:

• a vibration isolation pad with two opposite substantially planar surfaces;
• an elastic material layer permanently attached to a first of the two substantially planar surfaces of the vibration isolation pad;
• and
• a load sensor arrangement integrated into the combined elevator vibration isolation and load measurement element,
• whereby a load acting on the combined elevator vibration isolation and load measurement element can be measured with the load sensor arrangement as a function of the compression of the elastic material layer,
• wherein the load sensor arrangement comprises electrodes arranged at a distance apart from each other and attached to a first surface of the elastic material layer, a first electrical layer attached to a second opposite surface of the elastic material layer, whereby the distance between each electrode and the first electrical layer can be measured capacitively, said distance corresponding to the compression of the elastic material layer and thereby to the load acting on the vibration isolation pad, and
• wherein each of the electrodes is electrically connected to a specific part of an electrically conductive wiring, said specific part of the electrically conductive wiring forming an electrical output of said electrode, the electrically conductive wiring being further attached to an electrically insulating flexible foil.
