Measurement areas

Size of measurement areas, magnification and lateral resolution as well as slope angle depend on the used objective. The following objectives are available:

Type	Measurement area
	[mm]
10x 20x 50x	1,3 x 1,1 0,6 x 0,5 0,2 x 0,2

 

Others

Besides the objective the measurement head can be equipped with a miniature camera with an observation area of approx. 5 mm². This is helpful to find special structures or defects on the surface which are subsequently measured.

At the start the measurement head is automatically positioned so that the visually selected area is within the measurement area.
The measurement head is positioned using motors in axial, radial and circular directions. This is accomplished either visually by means of a joy stick, or by setting coordinates in a table.

Coordinates can easily be saved and later recalled. This enables the repositioning at exactly same point as before e.g. after test bench run. The unit is placed onto the center of the crankshaft housing. An adaptor is specially fitted to the engine to ensure the positioning reference for repetitive measurements. Furthermore, the inner cylinder wall is not contacted by the measurement system.

Customized software packages are available and a modified version for a production environment.
