A fiber-optic sensor is a that uses either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in. Depending on the application, fiber may be used because of its small size, or because no is needed at the remote location, or because many sensors can be along the length of a fiber by using light wavelength shift for.
Process control of large industrial plants has evolved through many stages. Initially, control would be from panels local to the process plant. However this required a large amount of human oversight to attend to these dispersed panels, and there was no overall view of the process. The next logical development was the transmission of all plant measurements to a permanently-staffed central control room. Effectively this w.
