Ultrasonic Pulse Echo Test System
Instrument Details
Make : Proceq, Switzerland
Model : Pundit PL-200PE
Specification : Housing specially designed to be used on-site in harsh environment, screen with highest resolution and sharpest image etc.
Working Principles
It is used to measure the propagation speed of a pulse of ultrasonic longitudinal stress waves. A pulse of ultrasonic longitudinal stress waves is introduced into surface of a concrete by a transducer coupled to the surface with a coupling gel or grease. The pulse travels through the concrete and is received by a similar transducer coupled on the other surface. The transit time of the pulse is determined by the transit time to obtain the pulse velocity.
Applications
- The homogeneity of concrete
- The presence of voids, cracks or other imperfections
- Changes in the concrete which may occur with time
User Instructions
- Surface to be tested, should be clean and free from dust.
- Transducers must be properly in contact with the surface to be tested.
