RY Strain Gauge Rosettes with 3 Measuring Grids for Analyzing Biaxial Stress States with Unknown Principal Directions

RY strain gauges have 3 measuring grids arranged at an angle of 0°/45°/90° (types RY1, RY3, RY8, RY9, RY10), or 0°/60°/120° (types RY4, RY7). These strain gauges (SGs) are an appropriate choice for analyzing the biaxial stress state with unknown principal directions.

With these types we offer you strain gauges (SG) in various geometries and sizes, each available with temperature responses adapted to the following materials:

  • Ferritic steel (10.8 ppm/K; 6.0 ppm/°F); temperature matching codes: 1
  • Aluminum (23 ppm/K; 12.8 ppm/°F); temperature matching codes: 3
  • Austenitic steel (16 ppm/K, 8.9 ppm/°F); temperature matching codes: 5
  • Silica/composite (0,5 ppm/K; 0.3 ppm/°F); temperature matching codes: 6
  • Titanium and gray cast iron (9 ppm/K; 5.0 ppm/°F); temperature matching codes: 7
  • Plastic (65 ppm/K; 36.1 ppm/°F); temperature matching codes: 8
  • Molybdenum (5.4 ppm/K; 3.0 ppm/°F); temperature matching codes: 9

Insert the temperature matching code in place of the placeholder “x” to get the ordering number of the strain gage you need. Strain gauges with # characterized are only available in matches for aluminum, ferritic and austenitic steel.

Save time and efforts: RY8 strain gauges are available as pre-wired versions with connection cable

Strain gauges available in 120 and 350 Ohms


Measuring grid consists of constantan, measuring grid carrier is polymide

The measuring grid consists of constantan; the material of the measuring grid carrier is polyimide.

RY6/RY8 strain gauges also come with a connection cable! One practical solution with many advantages: No soldering required at the measuring point, available in cable lengths from 0.5 m to 10 m, with RJ11 plug on request. A fluoropolymer-insulated wire on the strain gauge prevents the cable from sticking during installation. A practical solution for you...!
