FIELD: technology for registering seismic oscillations of soil and vibration.
SUBSTANCE: piezo-electric bending transformer with controllable resonance frequency contains two piezo-ceramic elements, and also two bushings with right and left thread respectively, and adjusting pin passing through them, while one ends of both piezo-ceramic elements are rigidly held between each other, and other ends are fastened to corresponding bushings, or each piezo-ceramic element and corresponding bushing are made as single whole structural element.
EFFECT: possible expansion of working band of frequencies without structural changes directly during measurements.
