FIELD: measuring devices.
SUBSTANCE: invention relates to measurement equipment and can be used to measure pressure, weight, deformations and stresses. Device comprises strain gages arranged at control points of object and connected with outer capacitors into phasing RC-circuit, thus forming together with amplifier generator of harmonic oscillations, connected via converter of frequency-code and microcontroller, which program is equipped with calibration characteristic of dependence of frequency of controlled mass or deformation, with digital display.
EFFECT: technical result consists in continuous measurements using two-wire communication line and similar standard resistance strain gauges (strain gauges).
