Abstract
Una celda de carga (1) comprende un cuerpo deformable (2) con una superficie de contacto superior (3) y una superficie de contacto inferior (4) las cuales están diseñadas para introducir una fuerza en el cuerpo deformable (2). Cada superficie de contacto (3, 4) contiene un punto de apoyo (5), con los dos puntos de apoyo reales (5) que definen una línea de acción (6) de la fuerza. Entre las superficies de contacto (3, 4) el cuerpo deformable (2) tiene por lo menos una porción en forma de columna (7) con un eje longitudinal central (8) y una superficie circunferencial cuya generatriz corre paralela al eje longitudinal central (8). La celda de carga además comprende un primer medio de determinación (9) el cual se instala en la porción en forma de columna (7) del cuerpo deformable (2) y convierte una deformación mecánica del cuerpo deformable (2) en una señal electrónica, y un segundo medio de determinación (10) el cual se instala en la porción en forma de columna (7) del cuerpo deformable (2) y convierte una desviación del eje longitudinal central (8) de la línea de acción (6) en una señal representativa. El primer medio de determinación (9) y el segundo medio de determinación (10) comprenden cada uno por lo menos un calibrador extensométrico. En particular, el por lo menos un calibrador extensométrico del segundo medio de determinación (10) está instalado esencialmente a mitad de camino entre la superficie de contacto superior (3) y la superficie de contacto inferior (4) y alineado en un ángulo agudo predeterminado con respecto a la generatriz de la superficie circunferencial de manera que la señal del segundo medio de determinación (10) es cero en ausencia de una desviación del eje longitudinal central (8) de la línea de acción (6).
