ABSTRACT:
Installation for the measuring of an essentially linear displacement of a body, with a fixed coil and axial direction of which corresponds to the direction of the displacement to be measured, a rod the magnetic permeability of which differs from the magnetic permeability of the medium which is surrounded by the coil, means for connecting said rod along the axis of the coil to that body the displacement of which should be measured, an A.C. source with constant amplitude and pulsation (angular frequency) causing a voltage drop in the coil, means electrically connected to the coil and generating a voltage signal dependent of and in phase with the voltage drop in the coil, means electrically connected in series with the AC current source, generating a signal proportional to and in phase with the current through the coil, means for phase shifting by 90.degree. with respect to the current one of said signals, which means are electrically connected to the means which generates the shifted signal, a device which operates as a multiplier for multiplying the phase-shifted signal and the other signal which device is electrically connected to the means for phase shifting and to the means for generating the non-shifted signal and a meter electrically connected to the device which operates as a multiplier measuring the signal obtained by the multiplication performed in the device.
