Abstract

This paper describes the workings of a new simple measurement of concentration in solutions using ultrasonic light diffraction effect based on Bragg mode. The concentration of NaCl solutions (0-20.0%) has been measured with a sensitivity of 139.1 mV/% at f_a = 94.02 MHz, and the sensitivity for sucrose solutions (0-20.0%) have reached 47.1 mV/% at f_a = 94.02 MHz. The sensitivity for NaCl solutions at the ultrasonic frequency of 94.02 MHz improves 11.2 times that at 9.898 MHz for solution-concentration sensor based on Raman-Nath mode and that of sucrose solutions improves 10.9 times
