Title:
MAGNETIC FLUX DETECTION SENSOR
Document Type and Number:
WIPO Patent Application WO/2011/125609
Kind Code:
A1
Abstract:
Disclosed is an inclination sensor (1) comprising a casing (2), a magneto-electric conversion element (8) and a movable body (12). The casing (2) comprises a movable body housing space (6) that houses a movable body (12) which comprises a hemispherical magnet. The movable body housing space (6) has a recessed curved surface (5) formed by a half-ellipsoid surface and which acts as an anisotropic surface to compensate for the anisotropy of the magneto-electric conversion element (8). 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).
