A soil displacement measurement device may include a cylindrical hollow housing; an outer ring-magnet slidably arranged on an exterior surface of the cylindrical hollow housing; an inner magnet disposed within the cylindrical hollow housing; a suspension arrangement suspending the inner magnet within an interior space of the cylindrical hollow housing; and a strain measurement element provided to a region of the suspension arrangement. A relative movement between the outer ring-magnet and the cylindrical hollow housing along a longitudinal axis of the cylindrical hollow housing may cause the outer ring-magnet to coact with the inner magnet in a manner such that a magnetic force between the two magnets changes a corresponding strain at the region of the suspension arrangement. The change in the strain may be detected by the strain measurement element as a measure of the relative displacement of the outer ring-magnet along the cylindrical hollow housing.
