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

Insert the temperature matching code in place of the placeholder “x” to get the ordering number of the strain gauge you need. Strain gauges marked with a # symbol are only available matched to 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

Fast delivery for preferred strain gauge types -  available from stock!

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...!

Simplified Documentation and Parameterization

To optimize the measuring point documentation each strain gauge includes two stickers which can be placed next to the measuring point and near the measuring amplifier. Benefit from the parameter information directly in the measurement setup:

  • QR code that directly links to the data sheet of the respective strain gauge
  • The product and production batch numbers
  • The k-factor and a additional space for your notes
  • QR code containing the values of the individual strain gauge to simplify computer-aided parameterization or documentation with a scanner

Please note: newly produced strain gauges all come with the sticker in stock, strain gauges still in stock do not have this feature yet.
