Abstract
A differential transformer is provided comprising an elongated bobbin having primary and secondary coils wound about separated sections. A ferromagnetic armature is movably disposed within a core of the bobbin for movement between the separated sections. A tube of electrically conducting material surrounds the bobbin core. The tube is formed of a material whose resistance varies with temperature in the same manner as the primary coil.
