Suspended target balance

A radiation force balance is used to determine the output power of a transducer system. There are several balance configurations available and it is useful for a user to be familiar with each type to determine which would be most appropriate for their measurement needs. The key components of a force balance are described below.

Radiation Force Balances are commercially available through companies such as Precision Acoustics, Ohmic Instruments, and Onda Corporation.
