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.Precision scale based on magnetostrictive amorphous thread. The scale is based on the increase in the impedance of the sensor wire, fed by high frequency current, as a consequence of the application of weight on the scale plate. The sensor element is constituted by: A magnetostrictive amorphous wire fed by a high frequency alternating current. Changes in impedance, as a consequence of the application of weights, are collected as an increase in electromotive force through a detector circuit. The scale allows to know the magnitude of the weight applied to the plate. The application of the scale is commercial, in the weighing of objects of up to 15 kg, such as food in stores or supermarkets.
