Abstract:
A cylindrical load cell having a longitudinal axis and capable of measuring six load components, comprisinga) at least two sets of strain gages, each set having at least three strain gages attached to said load cell;b) said at least three strain gages in one set of strain gages being approximately equally spaced from one another about the periphery of said load cell and oriented between approximately zero to sixty degrees relative to either side of the longitudinal axis of said cylindrical load cell;c) said at least three strain gages of a different set of strain gages being approximately equally spaced from one another about the periphery of said load cell and oriented between approximately forty-five to one hundred and twenty degrees from the at least three strain gages of the set of strain gages defined in paragraph (b) and between zero to sixty degrees relative to either side of the longitudinal axis of said cylindrical load cell;d) each of said strain gages in said at least two sets being wired to make an independent measurement operatively communicated to a computer processor to calculate the load components and compensate for drift and noise.
