INCLINOMETER (VERSIONS) Russian patent published in 1999 - IPC

FIELD: geophysics, geomagnetic navigation. SUBSTANCE: inclinometer can be used in well logging to determine angular position of borehole and body of inclinometer, in geomagnetic navigation to specify heading of vessel. Inclinometer includes body with gimbal frame placed inside it which rotation axis is collinear to longitudinal axis of body, weight/eccentric put on gimbal frame, two single-component magnetosensitive pickups positioned on gimbal frame and made fast to body, three single-component magnetosensitive pickups with mutually orthogonal sensitivity axes. In accordance with first variant inclinometer has three-component pickup of accelerometer made fast to body. In agreement with second variant inclinometer has single-component pickup of accelerometer made fast to body. In correspondence with third variant inclinometer includes single-component magnetosensitive pickup and single-component pickup of accelerometer made fast to body. EFFECT: simplified design, reduced mass and improved capability to establish angular position of body of inclinometer. 3 cl, 3 dwg
