Abstract
(EN) In general, in one aspect, a measurement system has measurement instrument having a first and second component. The first component is mechanically coupled to a first point on a shaft. The second component is mechanically coupled to a second point on the shaft. The measurement instrument is configured to generate an electrical displacement signal indicative of a displacement between the first and second components. A processor is in data communication with the measurement instrument, and the processor configured to: receive the displacement signal from the measurement instrument; receive a velocity signal indicative of a velocity; and based on the displacement signal and the velocity signal, produce an electrical power signal indicative of at least one of a torque applied to the shaft, or a power applied to the shaft.
(FR) En général, dans un aspect, un système de mesure a un instrument de mesure ayant des premier et second éléments. Le premier élément est accouplé mécaniquement à un premier point sur un arbre. Le second élément est accouplé mécaniquement à un second point sur l'arbre. L'instrument de mesure est configuré pour générer un signal de déplacement électrique indiquant un déplacement entre les premier et second éléments. Un processeur est en communication de données avec l'instrument de mesure, et le processeur est configuré pour : recevoir le signal de déplacement provenant de l'instrument de mesure ; recevoir un signal de vitesse indiquant une vitesse ; et, sur la base du signal de déplacement et du signal de vitesse, produire un signal de puissance électrique indiquant au moins un d'un couple appliqué à l'arbre ou d'une puissance appliquée à l'arbre.
