Abstract
A strain gauge transducer includes several features for enhancing operating life and improving measurement accuracy. Load force is applied transversely to the longitudinal axis of a load member that is configured to flex in the transverse direction in response to the load force, and the load member is constructed so that the material of the load member circumferentially surrounds device (e.g., one or more strain gauges) for measuring the force-induced flexure of the member. The load member and a mounting member that receives the load force and transfers it to the load member are configured to allow the mounting member to pivot about the axes of the load member and the mounting member and to inhibit the mounting member from moving along one of the axes. The ends of the load member are configured to roll within openings of side walls that support the load member above a base as said load member flexes in response to the load force.
