Abstract
Magnetic detector apparatus comprises a pair of electrically matched magnetic sensor assemblies supported at opposite ends of a titanium sensor tube of significant length. The sensor tube is supported in a liquid bath so as to resist gravitational forces tending to distort the sensor tube and thereby misalign the magnetic axes of the sensors. The excitation conductors of the sensors are connected in series with an electrically conducting path formed through the sensor tube by spider members in electrical contact with the tube interior and connected to the respective excitation conductors.
Claims5
Magnetic detector apparatus including a pair of substantially aligned magnetic sensor assemblies supported at axially spaced positions in an elongated sensor tube of sufficient length such that gravitational forces tend to distort the tube when it is disposed horizontally and cause misalignment of the sensor assemblies, characterized in that the apparatus includes means supporting the sensor tube in a liquid bath over a substantial part of its length between said sensor assemblies, with the length of the sensor tube substantially horizontal and with the interior of the sensor tube isolated from the liquid, for resisting said gravitational forces and maintaining the alignment of said sensor assemblies.
