Hylec Controls has introduced a new range of ultrasonic quality control and inspection meters for the testing of concrete, wood and ceramic products.
The V-Meter MK IV from Hylec Controls is a widely used and accepted testing instrument for quality control and inspection of concrete. Ultrasonic testing is recommended for a broad range of concrete structures including new and old structures, slabs, columns, walls, fire damaged areas, hydroelectric structures, pipe, prefab and pre-stressed beams, cylinders and other concrete forms.
Key capabilities of the ultrasonic testers including measuring and correlating concrete strength to standard strength measurement, permitting non-destructive testing of complete structures; and identifying honeycombs, voids, frozen concrete, cracks and other non-homogenous conditions in concrete. The V-Meter MK IV is available with a wide range of transducers.
Ultrasonic testing of wood using the V-Meter MK IV can help detect knots, shakes, splits, grain orientation, windfall cracks and presence of decay and rot in a non-destructive manner. The device also helps calculate basic parameters such as modulus of elasticity and density. The ultrasonic tester finds application in field testing of utility poles and structures, grading in the manufacturing process, fire ladder inspection, examination of laminates and paper roll density.
The pulse velocity of ultrasonic energy pulses traveling in a solid material is related to the density and elastic properties of the material. When ultrasonic energy is transmitted through a coarse grained material such as concrete, ceramics or wood, it is necessary for the wavelength of energy to be greater than the diameter of the largest grain particle. Typically, the 54 KHZ transducers are used for wood testing with the signal wavelength being about 3 inches (75mm). Finer materials require higher frequencies for optimum resolution.
The ultrasonic tester V-Meter MK IV has been successfully applied to a range of ceramic products including tile, refractory bricks and blocks, and kiln furniture as well as graphite. The ultrasonic pulse velocity testing technique has been used with positive results in an increasing number of refractory and ceramic applications, enabling users to improve their production processes, increase the integrity and quality of their products, and reduce scrap and reject rates, thereby saving both time and money.
