Optional Impact Devices ( Probes)

 

Application Fields:

The bearings and other parts, heavy work-pieces, metal material, pressure vessel, failure analysis of turbine generator unit and equipment

Mechanical or permanent assembly components have been installed, the test space is very narrow, requires the original record regular test results

Large work-piece within a wide range of more rapid test measurement site

Measuring Conditions:

The weight of measuring object must be more than 2kg.

The thickness must be more than 10mm.

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.

Special Supporting Ring ( use for different shape surface):
