Pulse Velocity Transducers
Proceq offers an extensive range of transducers providing highest accuracy and a proven field track record. The selection of the
correct transducer is dependent on the aggregate/grain size and the dimensions of the test object.

» Used for determination of elastic modulus
» Concrete, wood, rock (small samples only)
» Requires special shear wave couplant
*A pulse velocity of 3700 m/s (longitudinal wave) and 2500 m/s (shear wave) have been used for the computation of the
wavelengths.
