Measure, record, report

The microcontroller-based EdVel-1 is a sound velocity gauge/data logger combination (EdVel-1M) 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 EdVel (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 EdVel 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.
