Abstract
La presente invención es una celda de carga para la medición de fuerza, independientemente del desplazamiento, creada por medios tales como peso, aceleración, presión y similares. La celda de carga tiene una estructura de viga, con vigas posicionadas paralelas unas a otras en cuando menos un plano. En términos generales, estas vigas paralelas se conectan con un substrato estacionario y tienen un elemento de percepción conectado entre las dos vigas. En esta operación, la desviación de la viga crea una respuesta en elemento de percepción debido a la acción relativa ó a la desviación en la segunda viga.
