Abstract
A method and apparatus for sensing corrosion are provided in which an interrogation unit (14) transmits interrogation pulses and receives responses. A plurality of corrosion sensors (12) are disposed in the structure to be monitored (10), each of the sensors (12) generating an output. A plurality of responders (16) are powered from the interrogation pulses, one each of the responders (16) associated with one each of the sensors (12). The responders (16) are operable to transmit responses to the interrogation pulses based on the corrosion sensors' (12) output.
