    辐射力天平 用于医学超声诊断和治疗的高精度功率测量。为了满足美国FDA 510(K)、IEC61157和IEC61689的要求,必须对超声功率源的功率值进行精确测量。辐射力天平RFB可以对1MHz-10MHz,10mW-100W的功率进行精准测量。两种靶可选,可以单独测量也可以与计算机配套使用。


    CW标准声源 是为了定期对辐射力天平RBF和超声功率计进行规范校准,以确保功率测量仪器自身的准确性而满足国家测量标准。


    射力天平RFB

    Precision Acoustics RFB’s  is for a highly specified model suitable for the majority of medical diagnostic and physiotherapy ultrasound equipment: Using the suspended target the power generated by HIFU transducers can be measured

    ◇Calibrated frequency range:1MHz to 10MHz*.

    ◇Power range 20mW to 100W+ but the calibration range is 20mW to 10W*.

    ◇Overall measurement uncertainty* – for 50mW to 5W, less than +/-7% at 95% confidence.

    ◇For power levels greater than 100mW the typical type A (random) measurement uncertainties is typically 

    only 1%.

    ◇Maximum transducer diameter for absorbing well target  5cm* but the suspended target will accommodate large transducers -contact us with your specific requirements.

    *The RFB may be used outside of this range with increased uncertainty levels

    Listed are the options available for NPL calibrations which are traceable to the UK’s Primary Standard.

    ◇Calibration at 1 and 3MHz, Powers: 0.1W, 0.5W, 1W, 5W and 10W.

    ◇Calibration at single frequency at Powers to be agreed.

    ◇Calibration at 1 and 3MHz, Powers: 0.1W, 0.5W, 1W, 5W and 10W AND 3 Outputs in the range 10mW to

     1W at 0.928MHz and 3.151MHz AND 2 Outputs in the range 10mW to 200mW at 5.287MHz and

    7.415MHz and 9.541MHz.
