Abstract: A method of monitoring corrosion of an electrical enclosure in a hazardous environment is provided. The method is implemented with at least one computing device in communication with at least one FBG optical sensor reflecting UV light in the electrical enclosure. The method includes measuring wavelength changes of UV light reflected by the at least one sensor, wherein the wavelength changes are a function of corrosion-related strain in the electrical enclosure. The method also includes computing, by the at least one computing device, the corrosion-related strain in the electrical enclosure based on the measured wavelength changes. The method further includes comparing, by the at least one computing device, the computed corrosion-related strain with a predetermined threshold, and recommending preventive corrosion-related maintenance based on the comparison.

Abstract: A fluid system includes a controller, a control valve, and a fluid manifold. At least one solenoid may be connected to the fluid manifold, the control valve, and/or the controller. A first pressure sensor may be in fluid communication with an output of the control valve. A second pressure sensor may be in fluid communication with the fluid manifold. The controller may be configured to control operation of the control valve via the at least one solenoid according to a first fluid pressure obtained via the first pressure sensor and according to a second fluid pressure obtained via the second pressure sensor.
