INTRODUCTION
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.)
