Abstract:
A load cell which comprises:first and second spaced rigid outer beams which are straight and essentially parallel and which respectively define corresponding first and second end areas, at least one measuring beam located between said first and second outer beams and oriented essentially in parallel with said first and second outer beams, said at least one measuring beam comprising at least one measuring area, a first connection means for connecting said first end area of said first outer beam to said measuring beam, said first connection means comprising a first connecting beam which is attached to said first end area of the first outer beam at a first joint, said first connecting beam forming an angle &agr; relative to an imaginary plane defined by the first outer beam, a second connection means for connecting said first end area of said second outer beam to said measuring beam, said second connection means comprising a second connecting beam which is attached to said first end area of said second outer beam at a second joint, said second connecting beam forming an angle &agr; relative to an imaginary plane defined by the second outer beam, a third connection means for connecting said second end area of said first outer beam to said measuring beam, said third connection means including a third connecting beam which is attached to said second end area of the first outer beam at a third joint, said third connecting beam forming an angle &agr; relative to said imaginary plane defined by said first outer beam, and a fourth connection means for connecting said second end area of said second outer beam to said measuring beam, said fourth connecting means including a fourth connecting beam which is attached to said second end area of said second outer beam at a fourth joint, said fourth connecting beam forming an angle &agr; relative to said imaginary plane defined by said second outer beam, application of a perpendicular force to one of said first and second outer-beams creating a load on said at least one measuring area which is greater, smaller or the same as said perpendicular force in accordance with said angle &agr;.
