Abstract

A measurement coil (11) is connected to a voltage divider circuit (14) or bridge circuit. It is wound on to a core (28) and is moved relatively to a measurement tube (27). The measurement coil (11) has areas (11a, 11b, 11c) whose coil density differs in such a way that the voltage recorded at the output of the circuits has a linear characteristic curve corresponding to the movement of the measurement coil (11) relative to the measurement tube (27). It is possible to balance out the linearity errors in the voltage divider circuit (14) or bridge circuit, as well as the measurement errors in the measurement coil (11) due to the inhomogeneous magnetic field.
