Abstract

A corrosion protection element is described, with which in simple and cost effective manner a reliable corrosion protection of field devices can be provided, which field devices comprise at least one component of stainless steel in contact with an environment of the field device. Corrosion protection elements of the invention are distinguished by features including that they are embodied as sacrificial anodes comprising iron or rustable steel and have a form, which is embodied in such a manner that they can be applied to the component of the field device in such a manner that the sacrificial anode is in electrically conducting contact with the component.
