Abstract

Calibre electrónico de precisión (1) portátil, que comprende una corredera (1) apta para desplazarse longitudinalmente a lo largo de una barra (2), estando provistas la corredera y la barra, cada una, de una punta (10, respectivamente 20), estando provista la corredera, además, de medios electrónicos (11) que permite mostrar en una visualización electrónica (12) una indicación que depende de la distancia entre las citadas puntas (10, 20), comprendiendo los citados medios electrónicos medios autónomos (110, 111) de alimentación eléctrica, caracterizado porque la citada barra (2) está provista de una regla (21) magnetizada con un período de magnetización landa, porque los citados medios electrónicos (11) comprenden un solo captador (112) provisto de una red de n electrodos magnetorresistivos (1121) dispuestos frente a la citada regla (21) de modo que los valores de las resistencias de los electrodos magnetorresistivos son una función de su posición longitudinal a lo largo de la regla (21), siendo n superior a dos, y porque los citados medios electrónicos (11) comprenden, además, medios (112, 113) que permiten determinar, a partir de los valores de resistencia de los electrodos magnetorresistivos (1121), la citada indicación que depende de la distancia entre las citadas puntas (10, 20) y mostrar esta indicación en la citada visualización electrónica (12).
