Abstract

FIELD: measurement technology. SUBSTANCE: method of measurement of spread of cracks in current-carrying samples consists in measurement of voltage drop across section of sample having crack with the use of two measurement electrodes connected to sample on both sides of crack and in usage of its value as informative parameter. Measurement electrodes are made from heterogeneous materials. Constant difference of temperatures is created between their ends connected to sample and free ends. EFFECT: increased accuracy of measurements. 1 dwg
