dc.description.abstract This paper describes the development of a novel-type of load cell which possesses certain advantages over the normal pillar type. Sensitivity is greater since the two concentrically nested tubular load-carrying members are equally loaded in compression and tension and the strains of both are indicated. This construction is more tolerant of non-axial loading, and a simple modification allows the cell to respond only to the axial component of such loads. When the normal strain of the tubes is exceeded by overload, the base of the inner tube presses on the cell casing and the load is transmitted solidly, thereby allowing overloads of at least ten times normal full load to be carried without damage. The theoretical compression of the cell for full load is 0.001 in. and by suitable choice of strain gauges the cell may be made to drive galvanometers directly, or give an output of up to 0.25 V into a high impedance. en_US
