RFDA Professional

The RFDA professional is designed for automated impulse excitation measurements at room temperature. The RFDA professional system measures the resonant frequencies and internal friction or damping of samples and calculates the Young’s modulus, shear modulus, Poisson’s ratio of rectangular bars, cylindrical rods and discs according to the ASTM E1876-15 standard. Samples are mechanically tapped by an automated tapping device which allows the operator to determine the impact position and the excitation force accurately. The induced vibration signal is detected by a dedicated microphone with a large frequency range. These signals are amplified and send to a computer using a data acquisition board and afterwards, the elastic properties are calculated by the dedicated RFDA professional software. The user-friendly interface allows an easy interpretation and logging of the results..
