Abstract

DISPOSITIVO SENSOR ELECTRICO. EL DISPOSITIVO COMPRENDE POR LO MENOS UN TRANSDUCTOR PARTICULARMENTE UN TRANSDUCTOR DE PRESION DE PELICULA GRUESA, CONECTADA A UN CIRCUITO DE CONTROL DISPUESTO PARA EMITIR UNA SEÑAL DE VOLTAJE QUE ES VARIABLE EN DEPENDENCIA DE LA PRESION. INCLUYE ADEMAS UN CIRCUITO DE INTERFASE CONECTADO AL CIRCUITO DE CONTROL Y DISPUESTO, EN RESPUESTA A LA SEÑAL DE VOLTAJE, PARA PRESENTAR UNA RESISTENCIA DE SALIDA QUE ES VARIABLE DE CONFORMIDAD CON UNA CURVA DE RESPUESTA QUE ES PREDETERMINADA EN DEPENDENCIA DE LA PRESION DETECTADA POR A LO MENOS UN TRANSDUCTOR. EL CIRCUITO DE INTERFASE TIENE UNA SALIDA CONECTADA A UN CIRCUITO DE CONMUTACION QUE PUEDE CONMUTAR ENTRE PRIMERA Y SEGUNDA CONDICIONES EN DONDE PRESENTA UNA RESISTENCIA MINIMA Y UNA RESISTENCIA MAXIMA RESPECTIVAMENTE EN LA SALIDA. UN CIRCUITO CONVERSOR SUMINISTRA EL CIRCUITO DE CONMUTACION CON UNA SEÑAL DE CONTROL DE ONDA CUADRADA CON UNA VARIABLE DE CICLO OPERATIVO VALORES MAXIMO Y MINIMO EN DEPENDENCIA DE LA SALIDA DE SEÑAL DE VOLTAJE POR EL CIRCUITO DE CONTROL.
