A potentiometric displacement transducer converts displacement into

  • A.a charge proportional to the displacement of the wiper
  • B.a change of resistance and hence of output voltage
  • C.a change of capacitance between two moving plates
  • D.a change of inductance in a coil with a moving core

Answer: B

The wiper of a resistance element is moved by the quantity to be measured, so the resistance in circuit and the fraction of the supply appearing at the wiper both follow the displacement. It is simple, gives a large output and needs no amplification.
