The new ED-300XL is a low frequency eddy current instrument for measuring and sorting ferrous materials for hardness, alloy content, heat treatment and metallurgical structure. The unit compensates for surface roughness (lift-off), permitting accurate readings through .010" to .015" coatings of rust, dirt or scale. The ED-300XL's maximum eddy current penetration is approximately 1/8". Penetration depends upon the type and hardness of the ferrous material. As the sensing probe, or coil, detects a metallurgical variation, the instrument's needle (on the front panel) registers accordingly. Three front panel controls provide adjustment of sensitivity, compensation and balance for unit calibration.
Modular design of the 4.75" x 9" x 6" heavy gauge aluminum cabinet accommodates the basic ED-300XL unit and window gate for simple "go" and "no go" operations. Weight of the complete unit is 6 pounds.
The Centurion NDT ED-300XL is particularly suitable for ferrous foundries, heat treat shops, steel warehouses and general manufacturing plants...wherever quick, accurate tests must be made to segregate for metallurgical analysis and structure. For example, the instrument can separate gray cast from nodular cast iron. It can determine depth of case under certain conditions. The ED-300XL can distinguish between slight differences in alloy. And, it can measure hardness without damaging any parts. Note: all applications must be based upon readings of known samples.
The ED-300XL operates from a 110 volt, 60 cycle, A.C. line. The sensing probe is placed on a known sample and adjustments are made for sensitivity, balance and lift-off compensation. Once the instrument is properly set up, either manual or automatic testing may commence. The ED-300XL is constructed with rugged, durable, high quality materials to assure long, reliable service with minimum maintenance.
