Abstract
A method for the electrical measurement of the variation of a physical quantity transformed into a length variation, with the help of an air gap modulator, whose excitation winding is connected to a stabilized alternating voltage, and whose induced output voltage is measured and, by rectification of a continuous voltage, it is obtained as a measure for the physical quantity, characterized in that the air gap modulator is supplied with a rectangular voltage of constant amplitude and precise frequency, which, once modulated, is only taken into account The fundamental wave for the measurement, for which the output voltage of the air gap modulator is conducted to a measurement rectifier through an impedance transformer and a filter that follows said transformer.
