SRS™ - the ultimate artifact for the fast verification of 3D measurement devices

The SRS™ (Spatial Reference System) is the most modern, state of the art, three-dimensional measurement standard. The artifact is a gage, constructed from highly stabile and lightweight materials, designed to validate production and measurement instruments (3D coordinate measuring machines, mobile measurement systems, robots, machine tools, and other devices). The system’s simplest configuration is a bar with one magnetically attached steel ball at each end.

By combining multiple bars the system reaches its real strength of a true 3D gage. Not alike rearranging ball bars in a measurement volume, but through true spatial nominal angles highly precise 3D-shapes are created. The most powerful one is a tetrahedron, which can on one hand deliver 6 fast length comparisons, but also provides correction parameters for the system that is checked (e.g. pitch, roll and yaw on stationary CMMs).

The SRS™ bars offer high stability and repeatability due to a unique structural set up of its components that guarantee no dimensional influence through variation in humidity or temperature.

The SRS™ is dismountable and can easily be carried by one person. It is assembled in a matter of seconds. The SRS™ is calibrated by instruments traceable to the National Institute of Standards and Technology (NIST). SRS-E™ is the evaluation software that provides valuable and NIST-traceable statements about the actual performance of stationary and portable CMMs. SRSE™ is powered by the revolutionary INORA™-algorithms, which provide an error-robust evaluation of measurement data.
