Abstract

PURPOSE:To arrange so that measurement may be made with temperature compensation, by using two-system horizontal-wave oscillators whose respective oscillation directions are vertical to each other and seeking a differential in sonic velocity through measurement of the sonic velocity of a horizontal-wave ultrasonic based on the Singeround method. CONSTITUTION:An ultrasonic oscillator 3 and an ultrasonic oscillator 1 which oscillate in parallel and vertically with the direction of a stress acting on a stress medium 1 respectively, are adhered to a stress medium 1 and caused to oscillate in a direction of the arrows which are vertical with each other. Then a propagation velocity in the stress media 1 of the respective ultrasonic are measured at singerounds 5, 4 by the Singeround method and the singeround frequencies are counted by means of counters 7, 8. As a result, a stress generated on the stress medium 1 is thus easily computed on an arithmetic device 8. In addition, a temperature-attributed effect is offset on account of the two-system horizontal-wave oscillators 2, 3 employed.
