Transmission line moisture sensor

摘要

A sensor device for monitoring and testing for potential corrosion of structural elements is disclosed comprising a soluble material disposed adjacent to at least one conductor in a transmission line that reacts to the presence of moisture causing a detectable change in an electrical property of the conductor. The conductor may comprise a conductive ink that is disrupted when the soluble material dissolves beneath it. Alternately, the nonconductive soluble membrane may separate two conductors and moisture causes a disruption in the soluble membrane allowing the two conductors to short. Detected changes in the electrical properties of the one or more conductors can be used to indicate potential corrosion or structural imparement in the structural element. Connection to the sensor device may be through a connector or using a wireless reader which remotely energizes the sensor device comprising one or more RFID chips.
