HIGH-PERFORMANCE SENSORS Fast and accurate measurements with long styli and heavy styli configurations – that’s why the Leitz LSP-S2 probe head was developed. It is used in all Leitz PMM-G and PMM-F coordinate measuring machines. The Leitz LSP-S2 features a maintenance free measuring touch system which recognizes the normal direction of the surface, independent of its moving direction. The axes of the probe head are not clamped during the measurement; this means that the deflection of the measurement system always takes place perpendicular to the workpiece surface. The actual direction of the normal to the surface is determined in every probing point. Bending of the styli are always compensated correctly. The Leitz LSP-S2 combines outstanding accuracy with an The probe movements in the X, Y and Z directions are carried unmatched workload. Styli extensions up to 800mm length out with frictionless, hysteresis-free spring parallelograms with and up to 1000g weight can be used for the inspection of large high torsional stiffness. The deviation of each parallelogram components. is measured independently of the others using differential transformers. Naturally, the probe head is equipped with With the integrated automatic stylus changer for more collision protection. throughput, different styli configurations can be changed quickly and without re-calibration. With its outstanding PFTU-value* the Leitz LSP-S2 probe head system also allows form and roundness measurements, even The Leitz LSP-S2 is an almost maintenance-free measurement with very small tolerances. head, since no maintenance-intensive, self-moving parts or active force generators are present.There is an optional temperature sensor to automatically acquire workpiece temperatures during the measurement process. This results in more flexibility and a significant time saving. * PFTU = Single stylus form error acc. ISO 10360-5 LEITZ PMM-F / PMM-G | XXL-Class CMMs and Gear Inspection Centers 11
