Abstract
A dual range transducer is disclosed for accurately measuring loads in both low ranges and high ranges. The transducer includes an annular member having strain gauges mounted on side regions for measuring low loads applied between end regions of the annular member. When loads greater than the low ranges are applied to the end regions of the annular member, a gap closes and the loads are transferred through an anvil and a spindle which contains a second strain gauge for measuring the higher loads.
Claims5
A dual range load measuring transducer comprising an annular member having two diametrically opposed end regions and two diametrically opposed side regions spaced between said end regions, means for applying a load between said end regions, such load elastically deforming said side regions, first strain gauge means for measuring any force between said end regions deforming said side regions, an anvil, an adjustable spindle, means mounting said anvil on said spindle within said annular member in alignment with said diametrically opposed end regions and spaced apart to define a gap, said gap having a preselected adjustable spacing which closes when an applied load between said end regions exceeds a predetermined load whereby such predetermined load is the maximum load deforming said regions and any additional load above such predetermined load is transmitted between said anvil and said spindle, and second strain gauge means located on one of said spindle and said anvil for measuring any load transmitted between said anvil and said spindle.
