| Abstract: | The signals of strain gauge transducers are very small. In consequence, error signals can even exceed the measuring signal amplitudes and therefore must be suppressed by sophisticated measuring circuits. There are absolute physical limits for the resolution of strain gauge transducer signals and the carrier frequency technique can get very close to the boundary of theoretically achievable maximum resolution. Very high gain stability can be achieved with very precise inductive dividers as reference signal sources and with auto-calibration cycles. Realisations of the philosophy are shown for high-precision static measuring units and for universal broadband amplifier systems. |
