Title (EN) CORROSION-PROTECTION ELEMENT FOR A FIELD DEVICE
(FR) ÉLÉMENT ANTICORROSION POUR UN APPAREIL DE TERRAIN
(DE) KORROSIONSSCHUTZ-ELEMENT FÜR EIN FELDGERÄT
Abstract:
(EN) The invention describes a corrosion-protection element (1, 3) with which reliable corrosion protection of field devices can be implemented in a simple and cost-effective manner, the said field devices comprising at least one stainless-steel component which is in contact with an area surrounding the field device. Corrosion-protection elements (1, 3) according to the invention are distinguished in that they are designed as sacrificial anodes comprising iron or stainless steel and have a shaping which is designed in such a way that said elements can be attached to the component of the field device in such a way that the sacrificial anode is in electrically conductive contact with the component.
(FR) L'invention concerne un élément anticorrosion (1, 3) permettant d'obtenir de manière simple et économique une protection fiable contre la corrosion d'appareils de terrain qui comprennent au moins un composant en acier inoxydable se trouvant en contact avec un environnement de l'appareil de terrain. Les éléments anticorrosion (1, 3) selon l'invention se caractérisent en ce qu'ils sont réalisés sous la forme d'une anode sacrificielle contenant du fer ou de l'acier non inoxydable et présentent une forme qui est conçue de telle sorte qu'ils peuvent être montés sur le composant de l'appareil de terrain de telle manière que l'anode sacrificielle est en contact électroconducteur avec le composant.
(DE) Es ist ein Korrosionsschutz-Element (1, 3) beschrieben, mit dem auf einfache und kostengünstige Weise ein zuverlässiger Korrosionsschutz von Feldgeräten bewirkt werden kann, die mindestens eine mit einer Umgebung des Feldgeräts in Kontakt stehende Komponente aus Edelstahl umfassen. Erfindungsgemäße Korrosionsschutz-Elemente (1, 3) zeichnen sich dadurch aus, dass sie als Eisen oder rostenden Stahl umfassende Opferanode ausgebildet sind und eine Formgebung aufweisen, die derart ausgebildet ist, dass sie derart an der Komponente des Feldgeräts anbringbar sind, dass die Opferanode in elektrisch leitendem Kontakt zu der Komponente steht.
