Corrosivity Sensor
Abstract
A lightweight corrosively sensor is provided which is thin enough to be embedded between the layers of a composite structure or placed on a surface beneath a coating. It comprises a thin non-conductive base and two electrically isolated conductive elements fixed to the surface thereof. Each conductive element comprises a bus bar and a plurality of strips extending from the bus bar and interdigitated with the strips of the other conductive element. The corrosively sensor is connectable to a current measuring means for measuring the current across the two conductive elements as an indicator of the presence of a corrosive environment. A masking method of manufacturing such a sensor is also provided.
