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: Cadenas de galgas extensométricas para determinar gradientes de tensión o deformación

Las cadenas de galgas extensométricas de tipo KY1, KY2, KY3, KY4, KY5, KY6, KY7, KY8 y KY9 constan de 10 o 15 rejillas de medición muy pequeñas, situadas en un portador común y equidistantes entre sí, más una galga extensométrica de compensación. Las cadenas de galgas extensométricas resultan especialmente adecuadas para determinar gradientes de tensión o deformación.

HBM también ofrece cadenas de galgas extensométricas con múltiples rosetas y direcciones de rejilla de medición alternas, lo que también permite determinar gradientes de tensión biaxial. Las respuestas de temperatura de las cadenas de galgas extensométricas se adaptan a los requisitos del cliente. La resistencia nominal de las cadenas de galgas extensométricas es de 120 ohmios.

Si desea información más detallada sobre las mediciones con galgas extensométricas, consulte nuestra publicación técnica "An Introduction to Measurements Using Strain Gauges" (disponible en inglés).

La rejilla de medición está fabricada en constantán y el portador es de poliimida.
