Abstract
Improvements introduced in the object of the main patent number 344,537, requested on december 15, 1966, by "measurement procedure of a displacement", specifically in a device that makes application of said procedure, characterized in that a microwave generator feeds a measurement resonant cavity attached by a directive coupler to a detector, because the voltage produced by said detector governs an automatic frequency control member of said microwave frequency generator to set its frequency to the resonance frequency of the measurement cavity, and because a loop subordinates the resonance frequency of a reference cavity to the frequency of the wave provided by the microwave generator.
