Examples of Strain-Gauge Amplifier Linearity Results Using Combinatorial Calibration Method

• Abstract:

  The paper presents results of linearity check of some widely used amplifiers for strain-gauge force, torque and other transducers. The combinatorial method is employed to achieve better uncertainty of the linearity check than using traditional voltage ratio calibrator units. Results for 225 Hz and 4800 Hz carrier frequency amplifiers and a DC amplifier are presented.
