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: ひずみグラディアント確認用のKYひずみゲージチェーン

チェーンタイプのひずみゲージ(SG)KY1、KY2KY3KY4KY5KY6KY7KY8KY9は、同一のキャリア箔上に等間隔に配置された1015個の非常に小さい計測グリッドから構成されています。 SGチェーンはひずみグラディアント(勾配)を決定するのに特に向いています。

また、計測グリッド方向が交互に変化する複数のロゼットゲージからなるHBMSGチェーンを使用すると、2軸のひずみ状態のグラディアント(勾配)を決定できます。 SGチェーンの温度応答は顧客仕様に対応可能です。 SGチェーンの公称(定格)抵抗値は120Ωです。

SGチェーンによる計測の詳細情報は、「An Introduction to Measurements Using Strain Gauges(ひずみゲージによる計測の入門)」を御参照ください。

計測グリッドはコンスタンタンでできており、計測グリッドを保持している材料はポリイミドです。
