ABSTRACT:
A corrosion sensor having a housing carrying an electrical switch that has an actuator normally held in one switch operating position thereof by a corrosion sensing member of the housing and moving to another switch operation position thereof when the corrosion sensing member ruptures through the corrosion thereof caused by being exposed to a corrosive area, the corrosion sensing member also comprising a seal member for normally sealing the switch structure from the corrosive area until the corrosion sensing member ruptures. The housing has a chamber therein containing the switch and has an end provided with an opening leading to the chamber. The corrosion sensing member spans the opening to seal the chamber from the corrosive area. A flexible diaphragm is carried by the housing in stacked engaging relation with the corrosion sensing member and also spans the opening immediately adjacent the corrosion sensing member and intermediate the corrosion sensing member and the switch to seal the chamber from the corrosive area when the corrosion sensing member ruptures.
