Abstract

Patente de Invenção: <B>''CALIBRADOR ELETRôNICO PORTáTIL DE PRECISãO''<D>. Calibrador de precisão (1) portátil que possui um cursor (1) e uma haste (2) cada um deles munido de um bico (10, respectivamente 20). O cursor sendo por outro lado munido de meios eletrônicos (11) que permitem exibir em um mostrador eletrônico (12) a distância entre os bicos (10, 20). Os meios eletrônicos são alimentados por uma pilha (110, 111). A haste (2) é munida de uma régua (21) magnetizada com um período de magnetização <sym>. Os meios eletrônicos (11) compreendem um captor (112) munido de uma rede de eletrodos magnetorresistivos dispostos em frente à dita régua (21). Os valores de resistência dos eletrodos magnetorresistivos são uma função sinusoidal da posição longitudinal do captor (112) ao longo da régua (21). A rede de eletrodos magnetorresistivos compreende pelo menos certos jogos de eletrodos magnetorresistivos constituídos cada um deles por pelo menos 8 eletrodos ligados em série, de modo a aumentar a resistência elétrica dos jogos e a reduzir o consumo elétrico do conjunto do dispositivo.Invention Patent: <B> '' PRECISION PORTABLE ELECTRONIC CALIBRATOR '' <D>. Portable precision calibrator (1) that has a slider (1) and a rod (2) each equipped with a nozzle (10, respectively 20). The cursor, on the other hand, is equipped with electronic means (11) that allow the distance between the nozzles (10, 20) to be displayed on an electronic display (12). The electronic media are powered by a battery (110, 111). The rod (2) is provided with a ruler (21) magnetized with a <sym> magnetization period. The electronic means (11) comprise a sensor (112) equipped with a network of magnetoresistive electrodes arranged in front of said ruler (21). The resistance values of the magnetoresistive electrodes are a sinusoidal function of the longitudinal position of the sensor (112) along the ruler (21). The network of magnetoresistive electrodes comprises at least certain sets of magnetoresistive electrodes each consisting of at least 8 electrodes connected in series, in order to increase the electrical resistance of the games and to reduce the electrical consumption of the device as a whole.
