FIELD: instrumentation, measurement of vibration movements with low-frequency vibrations, for instance, fatigue tests of aviation structures. SUBSTANCE: resistance-strain gauge converter comes in the form of flat spiral from uniformly narrowing metal strip of constant thickness. Measurement tip is mounted for movement in guides, is made fast to center of spiral, perpendicular to its plane. Transducer is fixed immobile and is connected to tested object through measurement tip. Deformations of converter are recorded by resistance strain gauges which generate electric signals proportional to torsion stress. EFFECT: increased measurement accuracy, expanded measurement range, stability of results, increased operational reliability of transducer. 2 dwg
