A laboratory sample distribution system comprising a plurality of sample container carriers, each adapted to carry one or more sample containers, each carrier comprising at least one magnetically active device and at least one electrically conductive member, a transport plane adapted to support the carriers, a plurality of electro-magnetic actuators stationary arranged below the transport plane, the actuators being adapted to move the carriers on top of the transport plane by applying a magnetic force to the carriers, a plurality of inductive sensors distributed over the transport plane, a control unit configured to control the movement of the carriers using an output signal provided by the inductive sensors by driving the actuators such that the carriers move along corresponding transport paths, and an evaluation unit configured to linearize the output signal from an inductive sensor by means of a linearization algorithm.
