SPATIAL ELECTROMAGNETIC ACCELEROMETER Russian patent published in 1997 - IPC

FIELD: self-contained navigation systems and moving objects control systems. SUBSTANCE: ferromagnetic sensing mass 2 is suspended in the accelerometer ferromagnetic casing consisting of two halves 1. The suspension power elements are made in the form of eight electromagnetic coils 4 located in fours in each casing half 1 in two mutually perpendicular planes at angle α =54,7^° to the axis of symmetry. Variable-capacitance position pickups 6 of sensing mass 2 are connected to the follow-up system, including series- connected preamplifiers 7, linear transducer 8 of position pickup signals to an orthogonal coordinate system, correction units 9, linear signal transducer-distributor 10 and output amplifiers. The output of transducer-distributor 10 is also connected to electromagnetic coils 4. EFFECT: improved design. 5 dwg
