Sensing mechanism for linear servo accelerometer
Abstract
Abstract SENSING MECHANISM FOR LINEAR SERVO ACCELEROMETER HAVING A BODY WITH A SURFACE AND A YOKE MOUNTED ON THE SURFACE TO FORM AN AIR GAP OF A SUBSTANTIALLY CONSTANT WIDTH BETWEEN THE MAGNET AND THE YOKE THROUGH WHICH MAGNETIC LINES OF FLUX PAS. A FORCE COIL IS DISPOSED IN THE AIR GAP AND IS IN THE FORM OF A CLOSED LOOP LYING IN A PLANE WITH AN OPENING EXTENDING THERETHROUGH IN A DIRECTION PERPENDICULAR TO THE PLANE. MEANS IS PROVIDED EXTERIOR OF THE MAGNET FOR PIVOTALLY MOUNTING THE FORCE COIL ABOUT AN AXIS LYING IN THE PLANE IN THE COIL THE MAGNET EXTENDS THROUGH THE OPENING IN THE COIL AND HAS A SUBSTANTIALLY PLANAR SURFACE WHICH IS GENERALLY PARALLEL TO AND IS RELATIVELY CLOSE PROXIMITY TO THE PLANE. A CONDUCTING NON-MAGNETIC ELEMENT IS SECURED TO THE FORCE COIL FOR MOVEMENT WITH THE FORCE COIL AND AND A PICKOFF COIL IS MOUNTED ON THE SURFACE OF THE BODY FOR SENSING THE POSITION OF THE CONDUCTING ELEMENT. THE SENSING MECHANISM IS VERY COMPACT AND SMALL IN SIZE.
