美國Ohmic UPM-30超聲功率計，150 mW分辨率 UPM-30超聲功率計設計用于使用輻射力平衡方法測量高達30瓦的診斷或治療傳感器的超聲功率輸出。UPM-30由0.01至10.00克的精密機械秤，懸掛在吊架上的圓錐形目標，水箱，帶夾子的換能器支撐桿和手提箱組成。要測試的傳感器安裝在圓錐形靶上，傳感器的輻射面朝下浸入水介質中。 UPM-30型通過測量換能器對錐形目標的輻射力來確定超聲波的平均功率。該目標與用于測量由于超聲輻射引起的克機械力的精密機械平衡耦合。當乘以14.65的常數時，克力與超聲功率成正比，單位為瓦; 因此，2.05克力將等于30瓦的超聲輻射。 UPM-30裝置的核心是充氣圓錐形靶。通過使用自身的浮力，該目標的重量被降至最低。超聲波能量從目標機械地轉移到測量的精確平衡點。反射超聲能量被水箱內的閉孔丁基橡膠壁吸收。該系統提供了一個堅固的儀器，具有良好的測量精度和經濟的成本。  UPM-30超聲功率計標配包括以下附件： 金屬外殼 - 黑色 1克校準重量 NIST可溯源校準證書 用戶手冊 Ohmic’s Ultrasound Power Meter, Model UPM-30, is designed to measure the ultrasonic power output of diagnostic or therapeutic transducers up to 30 watts using the radiation force balance method. The UPM-30 consists of a precision mechanical balance which measures from 0.01 to 10.00 grams, a conical target suspended on a hanger, a water tank, a transducer support rod with clamp, and a carrying case. The transducer to be tested is center mounted over the conical target with the transducer’s radiating area immersed face down in the water medium. Model UPM-30 determines the average ultrasonic power by measuring the radiant force exerted by the transducer on the conical target. This target is coupled to the precision mechanical balance which is used to measure the gram-mechanical force due to the ultrasonic radiation. The gram force is directly proportional to the ultrasound power in watts when multiplied by a constant of 14.65; therefore, a 2.05 gram force would be equal to 30 watts of ultrasound radiation. The heart of the UPM-30 unit is its air-filled conical target. The weight of this target is nulled to a minimum by using its own buoyancy. Ultrasound energy is mechanically transferred from the target to the precision balance where it is measured. Reflected ultrasound energy is absorbed by closed-cell butyl rubber walls inside the water test tank. This system provides a sturdy instrument with good measurement accuracy and economical cost.
