美國Ohmic UPM-DT-50SP超聲功率計，50 mW分辨率
測量超聲功率的最可靠和可重復的手段是通過輻射力法。要測試的傳感器位于45°空氣錐形目標上方的脫氣水中。該聯軸器是用精度達到±0.15瓦的精密天平。當聲能施加到錐體時，合力與總輻射功率成正比。測試箱內襯聲波吸收橡膠以防止聲反射。天平被編程為將毫克量級的力直接轉換為具有良好分辨率的以瓦特為單位的讀數。功率計的測量精度可以通過在錐體的支撐臂上放置校準的重量來驗證。

The most reliable and repeatable means of measuring ultrasound power is by the radiation force method. The transducer to be tested is centered above a 45° air-backed cone target in de-gassed water. The coupling is made to a precision balance capable of resolving ± 0.15 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 prevent acoustic reflection. 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 calibrated weight on the cone’s support arm.
Features for the USP50SP:
? Resolution: 50mW (150 mW in grams mode)
? Measurement range: 0 to 30 Watts
? Frequency range: .5 to 10mHZ
? Measures pulsed or continuous power
? Selectable readout in watts or grams
? Battery or line-powered
? Digital liquid crystal display
? Optional RS-232 or USB interface
? Automatic zeroing & stabilization
? Five point certification (NIST traceable)
