    Measure, record, report

    The microprocessor-based DMV DL is a sound velocity gauge/data logger combination built into a small, portable instrument. Sound velocity measurements can be made throughout a plant, recorded on-site, and then sent directly to a serial printer or PC for immediate hardcopy reports, analysis, or permanent storage.

    Sound velocity measurements can be made on a wide range of materials with the DMV DL (i.e. cast iron, aluminum, plastics, and other metals and non-metals).

    Sound Velocity vs. Nodularity %

    Sound velocity is a prime factor in estimating the nodularity percentage (%) of ductile iron and its relative tensile strength. The mechanical properties of ductile iron are very dependent upon the shape of nodular graphite formations, or % nodularity, which has a direct effect on the sound velocity. As the nodularity % (graphite formation) increases, the sound velocity of the ductile iron also increases. In turn, sound velocity also has a relationship to the tensile strength of ductile iron, and is often used to predict or qualify the tensile strength of a casting. The DMV DL provides an excellent tool for spot checking production processes, sorting of suspect lots of material, 100% inspection of low volume production runs, and 100% inspection of critical safety-related ductile iron castings.

    Quick 2-step measurement

    A simple 2-step operation is all that is required to obtain sound velocity readings instantly on a large backlit LCD display.
