Compact for Measurements on PCBs and Small Spaces
Due to its tiny size, the strain gauge rosette RF9 in miniature is especially suitable for circuit boards and very small components.

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: 1-RF9x-0.8/120ZE
Pre-wired with thin, enameled copper wires and a 1 mm² measuring grid (JEDEC/IPC 9704-compliant): 1-RF9x-1/120ZE
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):1-RF9x-1.4/350ZE
Without a cable: 1-RF95-0.8/120_W

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