Abstract

Báscula de precisión basada en hilo amorfo magnetostrictivo. La báscula se basa en el aumento en la impedancia del hilo sensor, alimentado por corriente de alta frecuencia, como consecuencia de la aplicación de peso en el plato de la báscula. El elemento sensor esta constituido por: Un hilo amorfo magnetostrictivo alimentado por una corriente alterna de alta frecuencia. Los cambios en la impedancia, como consecuencia de la aplicación de pesos se recogen como un aumento de la fuerza electromotriz mediante un circuito detector. La báscula permite conocer la magnitud del peso aplicado en el plato. La aplicación de la báscula es comercial, en el pesaje de objetos de hasta 15 kg, como por ejemplo alimentos en tiendas o supermercados.
