Abstract

Un detector de fuga de rastreo (10) comprende un dispositivo portátil (44) con una sonda de punta de rastreo que comprende una entrada de gas de muestra (12), una entrada de gas de referencia (14), un analizador de gas (16) y una válvula de conmutación (20) adaptada para conectar, de manera alternativa, la entrada de gas de muestra (12) con el analizador de gas (16) y la entrada de gas de referencia (14) con el analizador de gas (16) en un modo de conducción de gas, de manera que, ya sea el gas extraído a través de la entrada de gas de muestra (12) o el gas extraído a través de la entrada de gas de referencia (14), es analizado por el analizador de gas (16), caracterizado porque la entrada de gas de referencia (14) es colocada en una distancia remota de la sonda de punta de rastreo y un conducto de gas de referencia (26) que conecta la entrada de gas de referencia (14) y la válvula de conmutación (20) comprende una cámara de amortiguación (40) adaptada para mezclar homogéneamente el gas extraído en la cámara de amortiguación (40) a través de la entrada de gas de referencia (14) con el gas restante en la cámara de amortiguación (40).
