Ultra-sonic beam

The sample holder can turned around in the YZ-plane (the transducers axis being the X-axis) to bring sample after sample into the ultra-sonic beam. The whole sample holder system can be rotated in the XY-plane to change the angle of incidence between 90° for longitudinal wave measurements, to 0° to perform shear wave measurements. Both transducer arms are moveable in the x-direction to change the... [Pg.111]

This experimental situation is drawn in Figure 4.14. The deviation of the ultra-sonic beam from the main X-axis, due to the shear waves is clearly visible. [Pg.119]

Accurate level measurement is also possible by use of ultra-sonic pulse transmission. The sound pulse is beamed onto the surface of the material/liquid to be measured and the time taken for it to bounce back to the source is converted into distance. This method is particularly useful in hazardous atmospheres. [Pg.89]
