Position detector for recording rotational/translational movements in a preset direction by counting has an exciting magnet and an induction coil assigned to a single ferromagnetic element

摘要

Motion to be recorded is represented by relative motion between an exciting magnet (EM) (2) and a ferromagnetic element (FE) (6). On reaching a set relative position, there is an abrupt release of energy along with magnetic field intensity. Accumulated with the help of the FE, the energy is bled off during a convergence between the EM and FE from kinetic energy for the motion to be recorded.
