Metrological characteristics
Linearity (force)
Linearity represents the maximum deviation/error between ideal and actual output signal characteristics in relation to the measurand in a specific measuring range. It is expressed in percentage of the range of measurement signal (Full Scale Output).

Ce couplemètre piézoélectrique à 2 composantess est adapté à la mesure d'une force de traction ou de compression Fz et d'un couple Mz agissant sur le capteur. La haute résolution permet de mesurer les moindres variations dynamiques de forces et de couples importants sur des arbres non rotatifs. Des disques de quartz sensibles à la pression et au cisaillement sont intégrés sous forte précontrainte entre une vis de précontrainte creuse et un écrou qui constitue le boîtier du capteur. En raison de la rigidité extrêmement élevée des éléments du capteur, les composantes Fz et Mz sont mesurées pratiquement sans modification de la course ou de l'angle. Le signal de charge proportionnel à la force et au couple est capté par des électrodes et transmis par un câble blindé à l'amplificateur de charge. Ce dernier convertit les signaux de charge en tensions de sortie proportionnelles, qui peuvent être enregistrées et évaluées.
