摘要： A sensor capable of measuring a number of physical parameters in a harsh environment includes a plurality of intrinsic fiber optic sensor elements formed within a core of an optical fiber, the optical fiber being disposed within a capillary tube made of a high strength, corrosion resistant material. The sensor is located at a distal end of the capillary tube, and the capillary tube is mounted in a monitoring location, such as mounted to the casing of an electrically submersible pump (ESP), such that the sensor can be utilized to measure physical parameters, including static and dynamic pressure, temperature, acceleration and acoustic signals, at the monitoring location. Each sensor is constructed such that a reference element, such as a rigid element, isolates a reference location in the optical fiber from mechanically induced strain. A Bragg grating sensing element is positioned with respect to the reference element, and responsive to an optical signal and to a strain associated with a respective measurand field for providing an optical sensing signal related to a magnitude of the respective measurand field.

摘要： A fused tension-based fiber grating pressure sensor includes an optical fiber having a Bragg grating impressed therein. The fiber is fused to tubes on opposite sides of the grating and an outer tube is fused to the tubes to form a chamber. The tubes and fiber may be made of glass. Light is incident on the grating and light is reflected from the grating at a reflection wavelength &lgr;1. The grating is initially placed in tension as the pressure P increases, the tension on the grating reduced and the reflection wavelength shifts accordingly. A temperature grating may be used to measure temperature and allow for a temperature-corrected pressure measurement.

摘要： A fiber optic Bragg grating pressure sensor particularly suited for measuring ambient pressure of a fluid includes a pressuring detecting device 12 such as a glass element whose elastic deformation is proportional to applied pressure. An optical fiber 28 with an integral first grating 33 is wrapped at least once around the device and has at least a portion of its length fused to the device 12 such that elastic deformation of the device 12 generates a corresponding axial strain in the fiber 28 and/or the grating 33 and thus a corresponding change of the fiber length and/or characteristic reflectance wavelength of the grating 33. A second grating 35 may be formed near the pressure detecting device 12 so as to sense ambient temperature but not be affected by deformation of the device 12 for temperature compensation. Also, the fiber 28 may have more than one grating or be doped at least between a pair of gratings 160,162, to form a fiber laser or a DFB fiber laser which lasing wavelength changes with changing pressure.
