    摘要: A current sensor for measuring a primary electrical current inducing a magnetic flux density defined over a known region comprises: a first sensor for measuring magnetic flux due to the primary current over a first predetermined area included within the known region; and a second sensor for measuring magnetic flux due to the primary current over a second predetermined area within the known region, the magnetic flux due to the primary current measured by the second sensor being a substantially predetermined calibrated amount different from the magnetic flux due to the primary current measured by the first sensor. The current sensor may further include a current source for generating a current inducing a magnetic flux density within the known region to at least partially offset the difference between the magnetic flux due to the primary current measured by the first sensor and the magnetic flux due to the primary current measured by the second sensor.

    摘要: An apparatus for detecting a measurand includes a fiber field access block having a clad fiber positioned in the fiber field access block such that a portion of the fiber is exposed to an outer surface and any cladding on that portion of the clad fiber is thinner than required to prevent an evanescent wave from escaping the clad fiber. A measurand sensitive layer is provided over the outer surface. A grating is present in either the measurand sensitive layer or the fiber. An optical source and an optical detection component are coupled to the clad fiber. The optical detection component measures shifts in output signals resulting from presence of the measurand in the environment of the fiber field access block caused by changing Bragg conditions which result from swelling of the measurand sensitive layer. The concentration of the measurand can be determined from the detected shifts.
