Abstract
DISPOSITIVO ELECTRONICO AUTO-CALIBRANTE TRANSDUCTOR DE PRESION PARA TUNELES REVESTIDOS. TRANSDUCTOR QUE COMPRENDE UNA VARILLA (1) QUE TIENE EN UN EXTREMO UN CABEZAL (1A) PARA EL CONTACTO EN LA ROCA, MIENTRAS QUE EN EL OTRO EXTREMO (3) ACTUA SOBRE UNA CELULA DE CARGA (20). EL TRANSDUCTOR ESTA DOTADO ADEMAS DE UN EXPANSIONADOR (2) INTEGRAL CON LA CELULA DE CARGA SOBRE LA CUAL ACTUA EL EXTREMO (3) DE LA VARILLA, ESTANDO REALIZADO DICHO EXPANSIONADOR (2) DE MANERA TAL QUE FIJA LA CELULA DE CARGA CON RESPECTO A LA OBRA CIVIL (13). DE MANERA PREFERENTE, LA CELULA DE CARGA (20) COMPRENDE UN DESMULTIPLICADOR (6) MAS ABAJO DEL CUAL QUEDA DISPUESTO UN PUENTE DETECTOR PIEZOELECTRICO (8).
