MarSurf. Surface Measuring Instruments and Systems MarSurf. Surface Probes Probes for virtually any application Description Non-skidded probes Today there is a clear trend towards skidless probes. Their strength lies in the fact that they are very versatile. The diamond tip is deflected relative to the ideal geometric profile of the datum plane in the drive unit. Advantages No skid-related filter effect Very short traversing lengths possible Calculation of W- and P-profile parameters Recording of profile angularity and increments Single-skid probes The most widespread in practice single-skid probes are supported on just one skid on the workpiece and therefore need to be aligned relative to the surface. Advantages Not sensitive to vibration because of very small measuring circle Suitable for curved test surfaces Inclination of the drive unit is uncritical Dual-skid probes Dual-skid probes are linked to the drive unit via hinges and align themselves automatically relative to the surface. They are ideal for flat workpieces. Advantages Very insensitive to vibration Minimal alignment required Optical probes (Focodyn LS 1 and LS 10 laser sensors) These optical probes work in a similar way to mechanical non-skid-ded probes. Following the principle of dynamic focusing the probe generates a sharp delimited focal point on the surface. Advantages Non-contact profile recording Also suitable for soft and sensitive workpiece surfaces
