- Abstract:
- Various approaches to bench-top Kibble balances are available worldwide. However, the literature has not disclosed a Kibble balance to measure ultrasonic radiation force (URF). Due to the nature of Kibble balances, assessing URF could be useful and even more valuable. This paper describes the development of a bench-top Kibble balance to measure URF. The system was compared to the Brazilian National Metrology Institute's primary standard for ultrasonic power measurement. Regarding the regular microbalance used for that purpose, the Kibble balance approach led to a smaller uncertainty in the 10 W to 20 W range.
