Abstract

EL CAPTADOR CONSTA DE UNA MEMBRANA DEFORMABLE BAJO EL EFECTO DE UNA MAGNITUD A MEDIR, UNA VIGA ENLAZADA A LA MEMBRANA PARA DETECTAR LOS ESFUERZOS TRANSMITIDOS POR LA MEMBRANA, Y UNOS INDICADORES EXTENSOMETRICOS FIJADOS A LA VIGA PARA SUMINISTRAR UNA SEÑAL REPRESENTATIVA DE LAS TENSIONES EJERCIDAS EN LA VIGA. LA MEMBRANA (16) Y LA VIGA (14) ESTAN HECHOS EN UNA SOLA PIEZA (10) EN LA CUAL LA PARTE QUE FORMA LA VIGA PRESENTA UN ESPESOR NOTABLEMENTE SUPERIOR AL DE LA PARTE QUE FORMA LA MEMBRANA Y QUE SE EXTIENDE ENTRE DOS ZONAS PERIFERICAS OPUESTAS DE ESTA ULTIMA, Y LA VIGA PRESENTA UNAS GARGANTAS O RANURAS (22,24,26,28) PARA CONSTITUIR EN LOS FONDOS DE LAS MISMAS UNAS ZONAS DE CONCENTRACION DE TENSIONES A LA ALTURA DE LAS CUALES ESTAN FIJADOS LOS INDICADORES EXTENSOMETRICOS (32,34,36,38).
