FIELD: mechanical engineering.
SUBSTANCE: device for measuring soil deformation additionally includes two frequency multiplexers, input of one of which through amplifier and generator is connected to generator of supporting frequency, and output - to input of phase detector. Input of another frequency multiplexer is connected through amplifier and generator to sensor of phase-modulated signal, and its output is connected to another input of phase detector.
EFFECT: increased precision and expanded measuring range.
