The inductive-voltage-divider-based digital amplifier DMP41 is the world´s most precise amplifier for strain-gauge-based sensors. It is the newest member of the DMP series, which has been optimized for decades as a reference device in mechanical laboratories of National Metrology Institutes (NMIs) around the world. The paper describes its innovative features, the characteristics and ideas behind this amplifier as well as the impact of its use in precision measuring chains for metrological applications.
