스트레인 게이지 트랜스듀서의 신호는 매우 미약합니다. 에러 신호가 측정 신호의 진폭을 초과 할 수 있기 때문에 정교한 측정 회로를 통해 이를 억제해야 합니다.
The paper discusses the problems and solutions for high resolution, high stability and efficient suppression and damping of error signals and unwanted dynamic signals.
It describes the absolute physical limits for the resolution of strain gage transducer signals and how 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.
