Abstract
An inductive sensor device () having a scale unit () and a sensor unit () that can be moved relative to each other in a measuring direction (M) is described. The scale unit contains scale elements () that are adapted to create a field pattern (P(x)) in measuring direction (M) that is detected by means of a receive circuit () of the sensor unit (). The receive circuit () contains at least a first receive coil set () and a second receive coil set () that are offset in measuring direction (M). In so doing a first spatial phase and a second spatial phase receive signal is provided by these receive coil sets () respectively. These spatial phases can be used for absolute position determination.
