VY Full Bridge Strain Gauges with 4 Measuring Grids for Measurements on Tension/Compression Bars and Torsion Bars and for Determining Shear Stresses

VY full bridge strain gauges (SGs) have 4 measuring grids, which are arranged so that each is offset to the next at an angle of 90°. Typical applications for full bridge SGs include measurements on tension/compression bars and torsion bars and determining shear stresses as they occur in shear beams.

With types VY1 (0°/90° T full bridge) and VY4 (shear/torsion full bridge) 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

VY: 4ゲージ式VYフルブリッジひずみゲージが引張/圧縮棒とねじり棒の上での計測を基に剪断応力を測定

Yフルブリッジひずみゲージ(SG)には4つの計測グリッドがあり、円周上に90°の間隔で均等に配置されています。フルブリッジSGの主な用途には、引張/圧縮棒とねじり棒上での計測とシアービームに起こる剪断応力の決定などがあります。

HBMの4ゲージ式フルブリッジひずみゲージには以下のようなタイプがあります:

· VY1  0°/90°T型フルブリッジ、鉄鋼か顧客仕様の温度応答への適合が可能(公称(定格)抵抗値120Ωで利用可能)

· VY4シアー/ねじりフルブリッジ、鉄鋼、アルミ、もしくは顧客仕様の温度応答への適合が可能(公称(定格)抵抗値120Ωと350Ωで利用可能)

VY1とVY4を使用した計測に関する詳細は小冊子「ホイストーンブリッジ回路の応用」と専門家向け文献「An Introduction to Measurements Using Strain Gauges(ひずみゲージによる計測の入門)」をご覧ください。

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