Abstract:
An electrical circuit for testing a transducer horn assembly, the electrical circuit being connected between the transducer horn assembly and an ultrasonic generator, the electrical circuit comprising:(a) a supply leg conductor though which a drive signal is transmitted from the ultrasonic generator to the transducer horn assembly;(b) a return leg conductor from the transducer horn assembly to the ultrasonic generator;(c) a transformer means for providing an output voltage which is proportional to the current in said supply leg conductor; and(d) a voltage divider connected between said supply leg conductor and said return leg conductor for providing an output voltage which is proportional to the voltage in said supply leg conductor, said voltage divider comprising a first resistor, a second resistor and a third resistor connected in series.
