MAGNETIC FLUX DETECTION SENSOR

摘要

Disclosed is an inclination sensor (1) comprises a casing (2), a magneto-electric conversion element (8) and a movable body (12). The casing (2) forms a movable body housing space (6) with a recessed curved surface (5) that faces upwards. The magneto-electric conversion element (8) which detects magnetic flux density in the height direction of the casing (2) is provided in the casing (2) and disposed on the underside of the deepest section (5A) of the recessed curved surface (5). The movable body (12) is formed by a hemispherical magnet wherein a sliding surface (13), formed by a downwards facing hemispherical surface, and a flat upper surface (14) have mutually reversed polarity. The moving body (12) is housed in the movable body housing space (6) when the sliding surface (13) is in the state of being slidably placed in the recessed curved surface (5). This enables the magneto-electric conversion element (8) to apply a magnetic flux density corresponding to the inclination angle (?) of the casing (2).
