The invention relates to measurement technology and is used to determine the absolute displacements of objects in metallurgy, automotive industry, warehouse and production logistics, and in the automation of production. The technical result is achieved when the following steps are performed: the displacement transducer is mounted on the object; signal sources are mounted along the trajectory of the object displacement; on each section of the trajectory, an arrangement of the signal sources is provided which is determined by changing the number of signal sources and/or the distance between any two signal sources; a signal is sent to the moving object with transducer; an output signal is received from the transducer regarding the location of the signal sources located within the measurement range; the object location is determined; furthermore, the displacement is measured at a distance exceeding the length of the active zone of the transducer.
