Abstract:
A load cell having an axis defining a direction, and comprising:a force receiver and a base for receiving force applied to said load cell, a first spring and a second spring, and force sensing means adapted to respond to said force applied to said load cell by generating a force signal, and wherein: each said spring comprises: a first part linked with said base for movement therewith, a second part linked with said force receiver for movement therewith and a uniting part unitary with said first and second parts, each said uniting part comprises a portion that is coplanar with a plane perpendicular to said axis, and said planes are offset from each other, whereby said force signal indicates the axial component of said force applied to said load cell and is insensitive to components having directions perpendicular to said axis.
