The tensometer design provides the use of a reference signal to increase sensitivity and compensation of phase incursion for registration the measured value relative to zero. Mechanical, optical and electronic components of high-frequency (f = 80kHz) tensometer made. Their installation and certification tests of the device are performed. Registration of the distribution of stresses in an ordered series of composite nanostructured samples showed that the limiting sensitivity of the tensometer system to internal stresses is 1 kPa, its spatial resolution is 5 microns.
