| The present application describes a linear position sensor (1) intending to solve the problem of achieving long linear position sensors with improved resolution and absolute positioning. For that, the linear position sensor (1) comprises an element (3) where sensor coils (7), (8), (9), (10) are disposed, and a partly electrically conductive element (2), both elements are moved relative to each other in a direction along a measurement path S0 to S2. Said partly electrically conductive element (2) comprises measuring tracks of two typologies, triangular shape type (5) and a discrete incremental step type (4), (6) providing each one fine and coarse resolution measurements respectively. The use of linear tracks - triangular shape - allows not only to minimize the degradation of the resolution of the sensor as the dynamic range of the sensor increases, but also allows to improve the sensor linearity due to the reduction of the harmonics that degrade the sensor response. |
