Abstract

TRANSDUCTOR OPTICO DE PRESION CON COMPENSACION DE TEMPERATURA. COMPRENDE UN DIAFRAGMA (12) CON UNA PESTAÑA (14), UNA DE CUYAS CARAS (16) TIENE HULE GUIAONDAS (18), FORMADO EN UNA DE LAS SUERFICIES EXTERNAS. TAMBIEN EXISTE UN GUIAONDAS DE ENTRADA (20) EN LA SUPERFICIE (16) DEL TRANSDUCTOR DE PRESION (10), ASI COMO UN GUIAONDAS DE SALIDA (26), EL CUAL VA DESDE UN PUNTO DADO (27) PASANDO POR UN PUNTO DE TRANSFERENCIA DE ENERGIA (28), HASTA UN PUNTO (30) SITUADO EN EL PERIMETRO DE LA PESTAÑA (14). EXISTE UNA FUENTE OPTICA (32), UN DETECTOR DE FRECUENCIA (34), PARA VERIFICAR LA ENERGIA LUMINOSA.
