Abstract
A load cell includes a base (40) with a cavity (42) formed therein. A diaphragm (46) is disposed over the cavity (42) to form a chamber (48) that is filled with hydraulic fluid. A piston formed of two halves (60) and (62) is disposed adjacent the surface of the diaphragm (46). A high tensile strength resilient membrane (58) is disposed between the two halves (60) and (62) of the piston and secured thereto with bolts (64) and (66). A securing ring (68) secures the diaphragm (46) around the periphery thereof to the base (40). A securing ring (72) secures the peripheral edge of the membrane (58) to the securing ring (68). The membrane (58) provides tension forces about the periphery of the piston to impede lateral movement thereof to maintain the piston in the center of the cavity (42).
