A control system and method utilizing one or more processors that are configured to determine contaminant loading of blades of a turbomachinery compressor based on one or more environmental conditions to which the turbomachinery compressor is exposed and one or more atmospheric air inlet conditions of the turbomachinery compressor. The one or more processors then determine a corrosion contaminant concentration on the blades of the turbomachinery compressor based on the contaminant loading that is determined and determine an upper limit on or a distribution of potential corrosion of the blades of the turbomachinery based on the corrosion contaminant concentration, at least one of the environmental conditions to which the turbomachinery compressor is exposed, and the corrosion contaminant concentration that is determined.

A system for monitoring the material changes in a structure is disclosed through the use monitoring instruments embedded within the structure. The instruments have at least one sensor with electrodes in contact with the surrounding material 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 digitized signals. The connection between the microcontroller and the data logger can be either through hardwire or RF. Power is provided to the electronic sensors through either external or local methods. A power management system can be used to place the electronics into a sleep mode when not in use. The electronics are encapsulated within potting material within an instrument case 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 to protect the electrodes and rounded adjacent connection lengths to prevent the case from developing cracks.
