摘要： The corrosion detection sensor detects corrosion to an electrical apparatus caused by a corrosive gas. The corrosion detection sensor includes a metal thin film to be corroded by the corrosive gas, a resistive element connected in series to the metal thin film, a resistance measuring instrument that measures a combined resistance of the metal thin film and the resistive element, and a notification unit that outputs a detection result indicating that the combined resistance measured by the resistance measuring unit is greater than a predetermined reference resistance. The reference resistance is determined according to a danger level indicating that the electrical apparatus is corrosively damaged by the corrosive gas.

摘要： A sensor includes three structures, a measurer to measure a resistance value, an analyzer to identify the type of a corrosive gas present in an environment based on the resistance value and corrosion resistance information of the three structures, and a notification device. The three structures include a first structure, a second structure, and a third structure. The magnitude relation in corrosion resistance between the three structures differs between a first environment, a second environment, and a third environment. The corrosive gas of the first type is present and the corrosive gas of the second type is not present in the first environment. The corrosive gas of the second type is present and the corrosive gas of the first type is not present in the second environment. The corrosive gas of the first type and the corrosive gas of the second type are both present in the third environment.

摘要： A frame plate forms a frame of an opening, and leads to side plates. On the frame plate, a spacer extends towards the opening. The spacer is folded back in the opening in the side plate directions, and is fixed to the inner surfaces of the side plates.
