ABSTRACT:
A flat-spread force measuring apparatus comprising a stiff rigid main body having an essentially plane top surface for receiving a load; a plurality of flat cavities provided in said body spaced to each other and extending in parallel to said top surface; essentially bubble free elastomeric material contained in said cavities; a plurality of pressure sensors one each arranged in contact to said elastomeric material in each of said cavities; a plurality of force introduction members one each arranged in an essentially vertical alignment to said pressure sensors and below them; and evaluation means electrically connected to said pressure sensors for combining electrical signals received therefrom and representing local force components transmitted from said load receiving body through said elastomeric material to said pressure sensors.
