Title (EN) TORQUE COMPENSATED WEIGHT SENSING MODULES
(FR) MODULES CAPTEURS DE FORCE A COMPENSATION DU COUPLE
Abstract:
(EN) A force sensing module comprising two or more load cells (27, 28) mounted vertically with output signals combined and adjustable to minimize longitudinal torque response. The force sensing module further comprises a vertical support for lifting and supporting a load, a support arm coupled to the vertical support for engaging and holding a load, first and second sets of strain gauges, spaced from each other and either in vertical or horizontal alignment with each other. The force sensing module also comprises first and second Wheatstone bridges (29, 30), wherein each Wheatstone bridge (29, 30) comprises one of the sets of strain gauges and at least one variable resistance (31, 32) coupled between the Wheatstone bridges (29, 30) with resistors (31, 32) adjustable to reduce the sensitivity of the Wheatstone bridges (29, 30) to torque applied to the sets of strain gauges through the support arm.
(FR) L'invention concerne un module capteur de force comportant un ou deux mesureurs de force (27, 28) montés verticalement, ayant des signaux de sortie combinés pouvant être réglés afin de minimiser la réponse de couple longitudinale. Le module capteur de force comporte également un support vertical (fig. 4) destiné à lever et porter une charge, un bras support couplé au support vertical afin d'engager et de maintenir une charge, et un premier et un deuxième ensemble de tensiomètres espacés les uns des autres et alignés horizontalement ou verticalement. Le module capteur de force est également composé d'un premier et d'un deuxième pont de Wheatstone (29, 30), chaque pont de Wheatstone (29, 30) comportant un des ensembles de tensiomètres et au moins une résistance variable (31, 32) couplée entre les ponts de Wheatstone (29, 30) au moyens de résistances (31, 32) pouvant être réglées afin de réduire la sensibilité des ponts de Wheatstone (29, 30) à un couple appliqué sur les ensembles de tensiomètres au moyen du bras support.
