RF (Roseta)

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
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.

Compact

The smallest variant is only 5 mm in diameter
Three stacked measuring grids
0.8 mm measuring grid length

If space is a constraint: Analysis of biaxial stress states with unknown principal stress direction in the most confined space

Easy handling

Various connection options
- Pre-wired with color-coded, enameled copper wires, 0.5 m wire length in a 2-wire configuration
- With 3 m TPE cable in a 4-wire configuration
- Without connection wires

No soldering on the strain gauge required
