The reason a full bridge of four active gauges is preferred in a load cell is that it gives

  • A.the lowest excitation current for a given output signal
  • B.an output that is independent of the excitation voltage applied
  • C.the largest output together with the best temperature cancellation
  • D.the highest resolution

Answer: C

Four gauges, two in tension and two in compression placed in opposite arms, give four times the output of a single gauge, and every change common to all four cancels. The output remains proportional to the excitation, so that must still be held stable.
