Strain Sensor Reference GuideCONSIDERATIONS FOR PARAMETER SELECTIONP arameter 1: Type of Strain measurementGage Series application (static, dynamic, post-yield, etc.) Operating temperature Test duration Cyclic endurance Accuracy required Ease of installationParameter 2: Test specimen materialS-T-C Number Operating temperature range Accuracy requiredParameter 3: Strain gradientsGage Length Area of maximum Strain Accuracy required Static Strain stability Maximum elongation Cyclic endurance Heat dissipation Space for installation Ease of installationParameter 4: Strain gradients (in-plane gage Pattern and normal to surface) Biaxiality of stress Heat dissipation Space for installation Ease of installation gage resistance availabilityParameter 5.
Strain Gage Dimensions Strain Gage Dimensions Gage length is an important consideration in strain gage selection, and is usually the fi rst parameter to be defi ned. Dimensions listed for gage length (as measured inside the grid endloops) and grid width refer to active grid dimensions.
