Miniatur Rosettes (RF9)

RF9 Strain Gauge Rosette for Printed Circuit Board Testing and Small Surfaces

Thanks to its three stacked measuring grids, the smallest version of the RF9 miniature SG rosette is only 5 mm in size. It enables biaxial stress states with unknown principal stress directions to be determined in the most confined of spaces, owing to its small diameter. The SG rosette is, therefore, particularly suitable for measurements on electric circuit boards or especially small components.

The following variants are available:

• Pre-wired with thin, enameled copper wires (d=0.2 mm) and a particularly small measuring grid
• Pre-wired with thin, enameled copper wires and a 1 mm² measuring grid (JEDEC/IPC 9704-compliant)
• Pre-wired with 0,1m enameled copper wires + 3 m temperature-resistant TPE cable (4-wire configuration), and a 2 mm² measuring grid (new and JEDEC/IPC 9704-compliant)
• Without a cable

The miniature rosettes are now also available with geometries that allow for measurements in compliance with the JEDEC/IPC 9704 standard.
