The article discusses electric safety sensors which use optical fibers as a sensing element. It has some advantages and, consequently, increases the requirements for safety and quality of production processes at oil refineries. The Faraday Effect is used as the basis for the construction of electric safety sensors based on optical fibers. The paper indicates that the magnetic-optical Faraday Effect is non-reciprocal, so it could be used to create a variety of non-reciprocal optical systems that transmit light in one direction alone. The application of the fiber-optic electric safety sensors is based on the determined magneto-optical Faraday effect found in processing units. Deep desalting (dehydration) of crude oil reduces corrosion and decreases the quantity of sediments found in the equipment; similarly it increases the units’ overhaul lifespan. The process’s quality is raised by increasing the efficiency of the electric dehydrators; it is determined by the parameters of the high-voltage power supplies for generating electrode voltage. The example touches on the application of modern electric safety sensors with the Faraday element in the control system of the technological process for oil desalting. Based on these examples, the document recommends automating the technological process system for oil desalting by using high parameters for multichannel optical fibers.
