By measuring the speed at which ultrasonic pulses travel through a material, the UPV method can assess its density, strength, and detect potential flaws such as cracks, voids, and honeycombs. This technique is widely used in construction, civil engineering, and material testing applications to ensure the reliability and durability of structures.Pulse generation: A transducer emits high-frequency ultrasonic pulses into the material being tested.Pulse propagation: The ultrasonic waves travel through the material, interacting with any defects or variations within its structure.Detection and measurement: A receiving transducer on the opposite side of the material (or at a different location on the same side) detects the transmitted pulse. The time taken for the pulse to travel from the transmitter to the receiver is recorded.Velocity calculation: The velocity of the pulse is calculated based on the distance between the two transducers and the time it took for the pulse to travel through the material.Higher velocity readings generally indicate a material of higher density and integrity, while lower velocities may suggest the presence of internal defects such as cracks, voids, or inconsistencies.Applications:Construction: Evaluate the quality of concrete structures such as buildings, bridges, tunnels, and dams. Detect flaws like cracks, honeycombs, and voids.Civil engineering: Assess the strength of concrete and rock in infrastructure projects.Manufacturing: Assess the quality of ceramics, composites, and refractory materials.Preservation and restoration: Assess historical structures for degradation or damage in masonry and concrete.Advantages:Non-destructive: No damage to the structure or material being tested.Accurate assessment: Provides precise information about material uniformity, density, and strength.Defect detection: Identifies internal defects such as cracks, voids, and honeycombs.Applicable to various materials: Concrete, rock, ceramics, and composites.Portable and efficient: Suitable for on-site and lab-based evaluations.Ultrasonic pulse velocity equipment from TEQTO:TEQTO offers a selection of ultrasonic pulse velocity testers (UPVT) designed for accurate, non-destructive assessments of material strength and integrity. These testers provide reliable, high-precision results for evaluating the uniformity of concrete structures or detecting hidden defects in rock or masonry.Key technical characteristics:Type of ultrasonic transducers: Undamped DPC transducersTransducer configuration: Array of 7 x DPC transducers, daisy wheel patternOperating frequency: 50 kHzSet delay range: 0 to 20 µsAdjustable base size: 50 to 2500 mmAutomatic Gain Control: switchableMax inspection object thickness: 2.5 mIndication resolution (time): 0.1 µsIndication resolution (velocity): 10 m/sSound velocity range: 1,000 to 15,000 m/sSound propagation time range: 0.1 to 10,000 µsRated supply voltage: 3.3 VOperation time with battery: ≥16 hoursDisplay: 2.8”, 320×240 pixelDimensions: 230×125×65 mmWeight: 420 gMean time between failures: 18,000 hoursService life: 5 years
