ABSTRACT:
In the load cell disclosed herein, relative displacement between bridging members or end caps mounted at different points along the axis of an elastic hollow cylinder is sensed by means of a variable reluctance transducer employing a pair of magnetically permeable core elements. One of the core elements is mounted on one of the bridging members and the other core element is C-shaped and mounted on the other bridging member with the ends of the C-shape in close proximity to the first core member thereby providing magnetic gaps whose widths are aligned with the cylinder axis. Windings around the ends of the C-shaped core provide electrical connection for an inductance which is variable as a function of the widths of the gaps and thus also of the axial displacement between the bridging members.
