Embeddable corrosion monitoring-instrument for steel reinforced structures

A system for monitoring the material changes in a structure through the use of monitoring instruments (40) is shown in Figure 1. The instruments (40) have at least one sensor (16, 48, 50, 160) with electrodes (42, 44, 52, 54, 56) in contact with the surrounding materials and electronics that are contained within the instrument. The sensor signals are converted to digital and transmitted to an external data logger or computer for display of the signals. The connection between the microcontroller (30) and the data logger can be either through hardwire (60) or RF. Power is provided to the electronic sensors through either external or local methods. A power management system (16) can be used to place the electronics in sleep mode when not in use. The electronics are encapsulated within potting material within an instrument case (600) that is manufactured from a material having a flexural modulus equal to, or greater than, the surrounding material to prevent mechanical failure of the device before failure of the surrounding material. The case has protective trays (540, 560) to protect the electrodes (42, 44, 52, 54, 56) and rounded adjacent connection lengths to prevent the case from developing cracks.
