Remote temperature monitoring apparatus and technique

Nuclear magnetic resonance sensing apparatus including

Nuclear magnetic resonance sensing apparatus and techniques

Nuclear magnetic resonance sensing apparatus including at least three magnets operative to generate a static magnetic field in a region remote therefrom containing materials sought to be analyzed, the at least three non-conductive permanent magnets being arranged along a longitudinal axis in side to side arrangement and having generally uniform cross sections, which, when joined, together define a circular cross section, the overall length of said at least three magnets along said longitudinal axis being greater than their dimensions perpendicular to said longitudinal axis and greater than twice the radial separation of said remote region and said longitudinal axis, the at least three magnets being magnetized in magnetization directions extending generally perpendicular to the longitudinal axis, at least one of the at least three magnets having a magnetization direction opposite to the magnetization direction of at least another one of the at least three magnets, the static magnetic field having a static field direction substantially perpendicular to the longitudinal axis and having generally uniform amplitude in the remote region; apparatus for generating a radio frequency magnetic field in the remote region for exciting nuclei of the materials sought to be analyzed and having a radio frequency magnetic field direction substantially perpendicular to both the longitudinal axis and to the static field direction; and apparatus for receiving nuclear magnetic resonance signals from the excited nuclei and for providing an output indication of the properties of the materials sought to be analyzed. Methods for nuclear magnetic resonance sensing are also described and claimed.
