FIELD: engineering of devices for measuring deformation of soil.
SUBSTANCE: device for measuring deformation of soil contains two working coils, positioned in substance being studied, alternating current generator and registration device. Also used is phase modulation, provided by resonance contour connected rigidly with one of working coils, which contour is adjusted to frequency of generator. Output of contour through signal generator and phase detector is connected to registration device.
EFFECT: increased precision of measurements.
