(Mahr Inc.: Providence, RI) -- Mahr Inc., a leading provider of dimensional metrology solutions, has introduced the Precimar SM 60, an easy-to-use length measurement instrument for fast and precise external measurements on shop floor parts, with a measuring range of 60 mm.

The SM 60 is configurable with Mahr readouts, such as digital indicators or linear variable differential transformer (LVDT) probes, to provide a system tailored to the performance level required for the measurement application. The SM 60 incorporates a 25 mm sensitive contact and a fixed reference jaw with a 35 mm adjustment to obtain the full 60 mm measurement capacity.

The robust construction of the SM 60 demonstrates its design for use in the production environment—right at the point of manufacture of precision parts. “This system fills the demand for high-performance gauging at the point of manufacture,” says George Schuetz, director of precision gages at Mahr. “It allows a machinist to easily set up and adapt for new workpieces, while allowing the system to act as either a long-range measuring system or as a very high-performance comparator for sub-micron applications.”

The user is provided the ability to select the best readout for level of performance and application of the measurement. Should versatility be the driving factor, a 25 mm MarCator 1086 or 1087 may be the indicator of choice with its large display or analog type dial. Having this range allows for measuring a wide range of size parts without having to adjust the system. If higher resolution and performance are required, a Millimar P2004 LVDT with ±2 mm range and C1200 bench amplifier are able to provide sub-micron performance at the machining process.

The optional measuring instrument, whether it be a long-range digital indicator or high-performance, short-range transducer, is always protected from over-range damage by the integrated coupling.

Hardened contact surfaces on both the sensitive and reference contacts ensure long life, even after measuring high volumes of part dimensions. For increased versatility, a family of measuring attachments for the standard contacts is available. These include contacts with radius surfaces, flat-edge contacts, and flat contacts with various diameters, allowing for plain outside diameter (OD) checks for adding gage pin wires, OD thread checking, and a threaded contact set for adding any of Mahr’s standard M 2,5 threaded contacts.

For easy part positioning, an easy-to-adjust support table is positioned up or down for proper part location and then locked into place. Retraction of the sensitive contact is accomplished with a simple retraction lever that is easy to use by right- or left-handed users. Additionally, if simple shaft OD’s are a requirement, a floating micro-center support option is available to mount shafts up to 160 mm within the measuring contacts of the Precimar SM 60.
