In article are suggest multifrequency ultrasonic transducer with stepped-plate disk. This device is mean for coagulation aerosols with 0.4 mum particle size. Also present method of engineering calculation stepped-plate radiator.
In the article construction of ultrasonic coagulation camera designed on the base of disk piezoelectric irradiator is described. The experimental results are also given, which prove its effectiveness. The developed construction of the camera insures not only aerosol coagulation but also further its settling.
