Sonic Viewer 2i

Sonic Bureau 2i uses ultrasonic waves to measure the propagation times of boring cores and rock specimens with high accuracy to determine the P-wave and S-wave velocities and to calculate the mechanical constants (dynamic Poisson's ratio, dynamic elastic modulus, and dynamic shear modulus).

Sandwiching a specimen between two transducers with matching characteristics, a high-voltage pulse is applied to one of the transducers to generate ultrasonic waves, and the other transducers receive the waves propagating through the specimen. The waves are captured by an ultra-high-speed A / D converter and shown on a display as waveform data, and propagation time can be read from the waveform with high accuracy. In addition, this equipment is equipped with an external trigger signal input mode, which enables high-speed data measurement of one channel.
