Title
(EN) INCLINATION SENSOR
(FR) DETECTEUR D'INCLINAISON
Abstract
(EN) An inclination sensor having excellent rotational performance, long-lasting stability and high sensing precision. The inclination sensor comprises a pendulum (10) rotatably attached to a case (1) of a fixed body secured to an attached member, a magnetic flux-generating means (11) attached to the pendulum (10), reed switches (4a) and (4b) attached to part of the case (1) corresponding to the locus along which the magnetic flux-generating means (11) moves, and a flange portion (12) which is a damping body being nonmagnetic and electrically conductive and disposed in the case (1) along the locus of the movement of the magnetic flux-generating means (11).
(FR) Détecteur d'inclinaison présentant des caractéristiques excellentes de rotation, de durée de stabilité et de précision de détection. Ce détecteur est composé d'un pendule (10) relié rotatif à un boîtier (1) constitué par un corps fixe accouplé à un élément de liaison, de moyens (11) de génération d'un flux magnétique reliés au pendule (10), de commutateurs à lames (4a) (4b) fixés à une partie du boîtier (1) correspondant au trajet le long duquel les moyens (11) de génération de flux magnétique se déplacent et d'une partie bride (12) consistant en un élément amortissant non magnétique, conducteur électriquement et situé dans le boîtier (1) le long du trajet de déplacement des moyens (11) de génération de flux magnétique.
