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.

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!
