Optional Impact Devices ( Probes)
Application Fields:
l The bearings and other parts, heavy work-pieces, metal material, pressure vessel, failure analysis of turbine generator unit and equipment
l Mechanical or permanent assembly components have been installed, the test space is very narrow, requires the original record regular test results
l Large work-piece within a wide range of more rapid test measurement site
Measuring Conditions:
l The weight of measuring object must be more than 2kg.
l The thickness must be more than 10mm.
l The surface roughness must be no less than 1.6μm.
Tips: If do not meet the above conditions, the measuring object should be laminated with steel substrate by coupling agents.
