High-precision amplifiers for strain gauge based transducers - First time realized in compact size

Abstract

In cases where accuracy matters, and in metrology of mechanical quantities such as force, torque or pressure this is definitely the case, are widely realized by transducers, which are based on strain gauges. To exploit the potential of the widely used high-precision static measurements the demands on precision amplifiers steadily grow. This paper gives exact details to further progress of the precision amplifiers used and how compact they can be realized nowadays.
