New Mahr Federal Gage Measures Contour and Roughness in Single Stroke



Laser-based Sensor Improves Range and Accuracy of Measurement

PROVIDENCE, RI -- The new MarSurf(TM) LD 120 from Mahr Federal is designed to improve the speed and reliability of surface and form measurement by combining both roughness and contour measurements into a single, integrated system. Utilizing a single drive unit, and incorporating a laser interferometer within the gage to improve the range and accuracy of measurements, the LD 120 has a traversing length of up to 120 mm (4.72 in.), and can measure both contour and roughness with a single stroke.

The LD 120 is a further extension of Mahr's modular Perthometer Concept for measuring and analyzing surface and form parameters both in the lab and on the shop floor. The system includes a drive unit, such as the LD 120, a PC with a data acquisition card, and menu-driven, Windows-based software which can be specified to provide complete roughness, contour, and profile analysis, depending on the user's application. A wide range of computer peripherals and measuring accessories is also available.

The benefits of the new LD 120 include an overall increase in the speed of measurement due to reduced set-up time, and an increase in accuracy due both to the laser-based displacement sensing unit and to the single set-up. The inherent accuracy and tight resolution (8 nm, or .315 µin.) of laser technology also facilitates lower tolerance measurements, making it possible to process a wider range of jobs than with other systems.

Using triangular support design, the LD 120 also incorporates an innovative tracing arm, ensuring maximum rigidity, low-oscillation measurements, and unwavering precision. Magnetic tracing arm mounts also provide system protection from accidental jarring and ensure long service life.

The MarSurf LD 120 uses a standard 2 µm (80 µin) radius diamond stylus tip, has a tracing arm measuring range of 10 mm (.394 in.), and provides a ratio of measuring range to resolution of 1.25 million to 1.
