ULTRASONIC PULSE VELOCITY TESTER 

Ultrasonic Pulse Velocity Tester

Product Code: MSI 2071

The Ultrasonic Pulse Velocity Tester is a high-precision, 4th-generation non-destructive testing (NDT) instrument engineered to assess the internal structural integrity, uniformity, and strength of hardened concrete. Developed through cooperative research with a national research institute of standards and science and subsidized by the Ministry of Science & Technology, this highly advanced system measures the travel time of high-voltage ultrasonic waves passing through solid materials with extreme accuracy.

The velocity of an ultrasonic wave through concrete is directly determined by its elastic properties and density. When concrete features excellent compressive strength and structural sound density, the transit time is remarkably short. Conversely, internal faults reduce wave speed. Equipped with highly efficient 52 kHz transducers, this instrument is purpose-built to propagate and capture signals effortlessly through highly attenuative composite materials including concrete, wood, stone, and engineering plastics.

🎯 Applications

🔬 Working Principle

The control unit generates a high-voltage electrical pulse and directs it into the transmitting transducer. This transducer converts electrical energy into an ultrasonic wave. The wave is transmitted into the concrete face, travels through the material's internal matrix, and is captured by the receiving transducer on the opposite or adjacent side.

The instrument records the wave transit time down to fractions of a microsecond. Because sound waves travel significantly faster through solid aggregate and dense cement paste than through air or water, a low velocity or delayed arrival indicates that the signal has encountered internal honeycombing, a void, or an intersecting crack line.
