Dual crystal contact probes play an important role in many practical ultrasonic inspections, so it is essential to develop an ultrasonic measurement model in order to get a thorough understanding of the characteristics of this kind of transducers. By combining the multi-Gaussian beam model and the Kirchhoff approximation scattering model, a complete ultrasonic measurement model is provided to predict testing signals of a flat bottom hole for a dual crystal focused direct contact probe. By comparing with experimental results, the accuracy of predicted signals using this model has been verified.
