KY Strain Gauge Chains for Determining Strain Gradients

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
  • 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, 350, 700 and 1,000 Ohms

Measuring grid consists of constantan, measuring grid carrier is polymide

KY: Chaînettes de jauges pour déterminer des gradients de contrainte

Les chaînettes de jauges de contrainte KY1, KY2, KY3, KY4, KY5, KY6, KY7, KY8 et KY9 se composent de 10 ou 15 grilles de mesure très petites, placées sur un même support à intervalle constant avec en plus une jauge de compensation. Les chaînettes sont particulièrement destinées pour déterminer des gradients de contrainte.

HBM fournit également des chaînettes de rosettes multiples et avec des grilles de mesure ayant des directions alternativement différentes, pour permettre de déterminer également des gradients de contraintes bi-axiales. Les réponses en température des chaînettes sont adaptées aux spécifications du client. L’impédance nominale des chaînettes est de 120 ohms.

Pour plus d'informations détaillées sur les chaînettes, vous pouvez vous référer à notre publication technique "An Introduction to Measurements Using Strain Gauges".

 

La grille de mesure est en constantan et le support des grilles est en polyimide.
