FIELD: measurement equipment.SUBSTANCE: measurements of characteristics of a disperse system are carried out with calibrated equipment and a photorecording device with subsequent determination of dependence between the signal of the calibrated equipment and the average diameter of particles identified visually, at the same time the liquid is exposed to ultrasound, thus a disperse system is created, it is illuminated with periodical pulses of light with duration of T?0.1T(where T- period of ultrasonic oscillations), synchronised with ultrasonic oscillations, during light pulses they measure the average diameter of dispersed particles with calibrated equipment and determine it on the basis of photorecording results (d.and daccordingly), the phase shift is changed between light pulses and ultrasonic oscillations, as well as ultrasound capacity, afterwards the measurements and photorecording are continued until the necessary quantity of the calibration levels is obtained, the calibration characteristic is determined as dependence of the value d.on d.EFFECT: simplified calibration due to exclusion of operations related to usage of reference powders, expansion of area of application due to calibration of instruments that realise integral methods of optics in disperse systems.2 cl, 3 dwg |
