One or more of the sensors is fixed upon a segment of magnetostrictive material, which is fixed to a rod, and may only be displaced longitudinally. The Fiber Bragg Grating Sensors have different wave lengths and are made of the same optical fiber. The magnetic or electromagnetic element included may be made of NdFeB (Neodymium Iron Boron) or metal alloys of TbDyFe (Terbium, Dysprosium and Iron), such as TX, Terphenol-D and others. It is applied to a control flow valve in an oil well, and it also refers to the calibration process of the position of the transducer.

摘要： A fiber optics differential pressure transducer (100, 200, 300, 400) containing Bragg networks (118), said transducer being used to measure the differential pressure in a Venturi installed inside a pipe (1), through which a fluid like oil is displaced. The transducer comprises a body (110, 230, 360, 410) of different geometries and a diaphragm (2), at least one Bragg network (118) being attached on each of the surfaces of the same. The diaphragm (2) is placed parallel or transversal to the transducer's body (100, 200, 300, 400). The transducer (200) is isolated from the process fluid by flexible mechanical seals (201) which transmit the pressure up to surfaces of the diaphragm (2). The transducer (300, 400) is provided with two relief microvalves for the purpose of protecting the sensor [diaphragms (2)] in overpressure events.
