Patent ID: 7915901

Claim:
An electrical resistance corrosion sensor assembly comprising: an elongate strip-like electrically conductive metal sensor element having selected metallurgical properties; a plurality of insulated wires respective ones of which are conductively connected to the sensor element at connection locations of the element at a first end of the element, a measure location, a location disposed substantially centrally between the measure location and a common location, the common location, a reference location, a check location, and a second end of the element, the connection locations serially spaced along the element; an elongate electrically nonconductive structural substrate to which the sensor element and the conductor wires are secured with the wires extending from and beyond the substrate; and an electrically nonconductive coating material covering and sealing the sensor element and the connections of the wires to the element except for the provision through the coating material of an opening to the surface of the element disposed between the common location and the first end of the element.
