Description of Ultrasonic Field
The spatial distribution of the radiated field is essentially a collimated beam of the ultrasonic energy having
a cross-sectional area of 8.5 cm
2
for the 10 cm
2
sound head when measured at a point 5 mm from the
transducer face.
The energy distribution within the radiated field is 2.4 w/cm 2 maximum and it takes a generally conic shape,
having decreasing intensity at progressively increasing distance from the face of the
transducer. This field distribution applies for the radiation emitted into the equivalent of an infinite medium
of distilled, degassed water at 30° C and with the line voltage variations in the range of 10% of the rated line
voltage.

having decreasing intensity at progressively increasing distance from the face of the transducer. This field
distribution applies for the radiation emitted into the equivalent of an infinite medium of distilled, degassed
water at about 30° C and with power line variations in the range of +/- 10% of the rated voltage.
