Suggestions for the improvement in the design of ultrasonic transducer for non-destructive testing in liquid mediums

The variants of changing the design of an ultrasonic sensor intended for immersive non-desctructive testing in a liquid medium, leading to the improvement of its basic acoustic characteristics, are considered. Theoretical and experimental studies of the influence of the parameters of the utilized acoustic delay body on the amplitudes of the recorded signals from the interface between the medium in the conditions of the specific problem under consideration are presented. Suggestions are made for improving the design of the device in order to obtain the best conditions for non-destructive testing.
