Abstract

The displacement sensor (100) includes a rod (103) including a conical convex graduated magnetically anomalous region (105) and a magnetic sensor (110) located in close proximity to the concical convex graduated magnetically anomalous region (105). The magnetic sensor (110) generates a positional signal that is related to the position of the concical convex graduated magnetically anomalous region (105) in relation to the magnetic sensor (110).
