Title (EN) RESCALEABLE INCLINOMETER
(FR) INCLINOMETRE A ETENDUE DE MESURE RAJUSTABLE
Abstract:
(EN) An inclinometer (300) includes a sensing unit (302) for providing a signal dependent on the orientation of the inclinometer (300). The inclinometer (300) includes a rescaling unit (322) which improves the performance of the inclinometer providing additional compensation for any change in the sensor (302) over time and temperature. The inclinometer (300) further includes an angle offset function (91, 360) which provides a permanent angle offset to any angle determined by the inclinometer.
(FR) L'inclinomètre décrit (300) comprend une unité de détection (302) qui fournit un signal dépendant de l'orientation de l'inclinomètre (300), une unité de rajustement de l'étendue de mesure (322) qui améliore la performance de l'inclinomètre en assurant une compensation supplémentaire pour tous les changements se produisant dans le détecteur (302) en fonction du temps et de la température, ainsi qu'une fonction de déplacement angulaire (91, 360) qui confère un déplacement angulaire permanent à n'importe quel angle déterminé par l'inclinomètre.
