Abstract

CIRCUITO DE CONEXIONES PARA UNA SONDA (SV, SH) EXENTA DE POTENCIAL, Y PROCEDIMIENTO DE COMPROBACION PARA LA CORRECTA CONEXION DE LA SONDA, CON UNA LINEA DE POTENCIAL BAJO (NPL_V, NPL_H) Y UNA LINEA DE POTENCIAL ALTO (HPL_V, HPL_H) QUE ESTAN CONECTADAS A UN AMPLIFICADOR (AMP_V, AMP_H) QUE ESTA CARACTERIZADA PORQUE; - LA LINEA DE POTENCIAL ALTO ESTA ENLAZADA CON UNA FUENTE DE TENSION OFFSET (UP) Y - EL AMPLIFICADOR OBTIENE COMO TENSION DE ENTRADA (UIN_V, UIN_H) LA DIFERENCIA ENTRE LOS POTENCIALES EN LA LINEA DE POTENCIAL ALTO Y LA LINEA DE POTENCIAL BAJO Y ENTREGA COMO TENSION DE SALIDA (UOUT_V, UOUT_H) LA DIFERENCIA ENTRE LA TENSION OFFSET Y LA TENSION DE ENTRADA AMPLIFICADA; - ELIGIENDOSE LA TENSION OFFSET DE TAL MANERA QUE CUANDO LA SONDA ESTA CONECTADA CORRECTAMENTE LA TENSION DE SALIDA ES SIEMPRE CLARAMENTE MAYOR DE CERO PERO MENOR QUE UNA TENSION UMBRAL (U_REF) PREDETERMINADA.
