ABSTRACT:
A strain sensor is provided which includes a base member and a pair of mounting points for mounting the base member to a support structure supporting a vessel for weighing the contents of the vessel. The base member defines a cylindrically shaped well located at the center of base member. The area of the base member within the well defines a pair of apertures symmetrically located on opposite sides of a central longitudinal axis of the base member. The base member also defines a pair of notches located on opposite edges of the base member which run parallel to the longitudinal axis of the base member. An axial strain sensing element is mounted in the well along the longitudinal axis of the base member for sensing the axial strain in the support structure. In addition, a transverse strain sensing element is mounted in the well perpendicular to the axial strain sensing element for detecting strain a direction transverse to the longitudinal axis of the base member.
