KY strain gauges (SGs) consist of 10 or 15 very small measuring grids that are placed on a common carrier at a constant spacing (equidistant apart) plus one compensation SG. SG chains are especially suitable for determining strain gradients.

With types KY1, KY2, KY3, KY4, KY5, KY6, KY7, KY8 and KY9 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

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, 350, 700 and 1,000 Ohms Measuring grid consists of constantan, measuring grid carrier is polymide Fast delivery for preferred strain gauge types - available from stock!
