RF9: Strain Gauge Rosette for Printed Circuit Board Testing and Limited Spaces

Thanks to its three stacked measuring grids, the miniature rosette RF9 is only 5 mm in size. Its small diameter enables it to determine a biaxial stress state with unknown principal stress direction in the most confined space. The SG rosette is therefore particularly suitable for measurements on electric circuit boards or especially small components.

The RF9 is available in two variants:

  • With presoldered color-coded enameled copper wires: 1-RF91-0.8/120ZE
  • With solder pads (without cooper wires): 1-RF91-0.8/120_W

Compact

  • Only 5 mm in diameter
  • Three stacked measuring grids
  • 0.8 mm measuring grid length

If there's not much space: Analysis of biaxial stress states with unknown principal stress direction in the most confined space

Easy handling

  • Pre-wired with color-coded enameled copper wires
  • Wire length 0.5 m

No soldering on the strain gauge

Available immediately
