Abstract: A corrosion sensor for detecting the action of corrosive media on a metallic component when the sensor is mounted in the vicinity of the metallic component in use is disclosed. The sensor includes an electrically conducting corrodible element mounted on a non conducting substrate, the corrodible element being covered with a protective coating such as paint adapted to protect the corrodible element from corrosive media. The protective coating defines a temporary feature such as a paint defect which extends across the corrodible element and is designed to permit attack on the corrodible element by corrosive media after a predetermined period of time. The corrodible element comprises a pair of spaced tracks extending generally in a longitudinal direction and a series of corrodible tracks, each corrodible track extending generally in a lateral direction and forming an electrical connection between the spaced tracks. The temporary feature extends longitudinally, in the space between the pair of tracks, across a number of the corrodible tracks whereby to permit a corrosive attack on a number of the corrodible tracks after the predetermined period of time
Abstract translation: 公开了一种用于在传感器安装在使用中的金属部件附近时用于检测金属部件上的腐蚀性介质的作用的腐蚀传感器。 传感器包括安装在非导电衬底上的导电可腐蚀元件，可腐蚀元件被保护涂层覆盖，例如适用于保护可腐蚀元件免受腐蚀性介质的涂料。 保护涂层定义了临时特征，例如延伸穿过可腐蚀元件的油漆缺陷，并被设计成允许在预定时间段之后通过腐蚀性介质侵蚀可腐蚀元件。 可腐蚀元件包括大致沿纵向方向延伸的一对间隔的轨道和一系列可腐蚀的轨道，每个可腐蚀的轨道大体上沿横向方向延伸并且在间隔的轨道之间形成电连接。 临时特征在一对轨道之间的空间中纵向延伸穿过若干可腐蚀的轨道，从而允许在预定时间段之后对若干可腐蚀轨道进行腐蚀性攻击
