The USP-50SP uses a 5¡± diameter, 3 1/2¡± high test

tank. To measure ultrasound power, the USP-50SP

uses the reliable radiation force method. Testing a

transducer is simple. Start by centering the transducer

above the 45¡ã airbacked cone target in degassed

water. The coupling is made to a precision balance

capable of resolving ¡À0.15 watts. When acoustic

energy is applied to the cone, the resultant force is

directly proportional to the total radiated power. The

test tank is lined with sonic absorbent rubber

to porvent acoustic refleetion the balance ,is

programmed to convert milligram magnitude forces

direct to a readout in watts with good resolution.

Measurement accuracy of the power meter can be

Verified by placing a calibra bed weidht on the con’s

support arm. (The supplied 1 gram calibration weight

equals 14.7 watts.)
