Abstract

DISPOSITIVO DE DETECCION DE UNA REGION CALIENTE DE UN OBJETO. FORMADO POR UN ELEMENTO DE FIBRA OPTICA DISPUESTO EN LAS PROXIMIDADES DE UN OBJETO Y EN EL INTERIOR DE UN AMBIENTE A UNA TEMPERATURA DETERMINADA, FUNCION DE LA TEMPERATURA DEL OBJETO. DICHO ELEMENTO AUTOGENERA UNA RADIACION TERMICA, VARIANDO LAS LONGITUDES DE ONDA DE LA COMPOSICION EXPECTRAL DE LA RADIACION TERMICA EN EL SENTIDO LONGITUDINAL DE LA FIBRA OPTICA EN FUNCION DE LAS VARIACIONES DE TEMPERATURA DEL OBJETO. DE APLICACION, ENTRE OTRAS, AL MANTENIMIENTO PREVENTIVO DE MOTORES ELECTRICOS POR DETECCION DE ZONAS CALIENTES EN EL MISMO.
