Abstract
A transducer for sensing forces in a single axis. A beam (14) which may be the draft link of a tractor is provided with an intermediate central beam (32) defined by two relatively narrow parallel slots (30) disposed closely adjacent to the neutral plane (34) of the beam (14). The central beam (32) is provided with a reduced cross sectional area (44) which acts to mechanically amplify tensile and compressive loads applied along the axis of the beam. Strain sensing means, which may be strain gauges, are associated with the reduced cross sectional area. The slots (30) and reduced cross sectional area are formed by wire electro discharge machining.
