Abstract
A linear actuator for a variable-geometry member of a turbocharger includes a piston/rod assembly that can axially translate and also pivot to a limited extent. A permanent magnet is mounted in a fixed position within the actuator. A non-magnetized flux carrier is mounted in the piston/rod assembly, and its movement alters the magnetic field of the magnet. A Halls effects sensor detects the magnetic field and the signals produced by the sensor are used for determining axial position of the piston/rod assembly.
