Abstract

DISPOSITIVO PARA LA MEDICION DE UN RECORRIDO O DE UN ANGULO, DEL QUE SON COMPONENTES PRINCIPALES UNA BOBINA, UN ELEMENTO DE AMORTIGUACION DE MATERIAL CONDUCTIVO ELECTRICAMENTE, MOVIL CON RESPECTO A LA BOBINA, ASI COMO UN DISPOSITIVO PARA DETERMINAR LA INDUCTANCIA DE LA BOBINA EN DEPENDENCIA DE LA POSICION DEL ELEMENTO DE AMORTIGUACION EN RELACION CON LA BOBINA. AL MENOS UNA BOBINA (1) TIENE APROXIMADAMENTE LA FORMA DE UN TRAPECIO CUYAS BASES ESTAN DISPUESTAS PERPENDICULARMENTE CON RESPECTO A LA DIRECCION DEL MOVIMIENTO RELATIVO DE LA BOBINA Y EL ELEMENTO DE AMORTIGUACION, Y CUYO ANCHO VARIA A LO LARGO DE ESTA DIRECCION.DEVICE FOR MEASURING A TRAVEL OR ANGLE, OF WHICH A COIL, A DAMPING ELEMENT OF ELECTRICALLY CONDUCTIVE MATERIAL, WITH RESPECT TO THE COIL, AS WELL AS A DEVICE TO DETERMINE THE INDUCTANCE OF THE BOB, ARE MAIN COMPONENTS THE POSITION OF THE CUSHION ELEMENT IN RELATION TO THE COIL. AT LEAST ONE COIL (1) HAS APPROXIMATELY THE SHAPE OF A TRAPEZE WHOSE BASES ARE PERPENDICULARLY DISPOSED WITH REGARD TO THE DIRECTION OF THE RELATIVE MOVEMENT OF THE COIL AND THE CUSHIONING ELEMENT WHICH WILL VARY THROUGH THIS.
