Bilateral comparison of ultrasonic power (10 mW to 15W) in the frequency range from 1.8 MHz to 11 MHz

Proposal, 15 November 2005

 

The aim of the project is comparison of the measurement systems of the ultrasonic power, based on the radiation force balance, by measuring the conductance of an ultrasonic standard transducer.

 

The value of the radiation conductance is calculated from the electric input power to the transducer and the ultrasonic output power emitted by the transducer into an anechoic water volume at room temperature.

 

The ultrasonic power investigated is from 10 mW to 15 W in frequency range from 1.8 MHz to 11 MHz.
