Strain Sensor Reference GuideCONSIDERATIONS FOR PARAMETER SELECTIONParameter 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: Heat dissipationGage Resistance Leadwire desensitization Signal-to-noise ratioParameter 6.
The strain gage readings are stable from power-up and with no load applied. 2. The gage circuits have nearly infinite resistance to ground (>10k MΩ). ... normally used in static measurements due to very high thermal-output characteristics. Dynamic: –320° to +400°F (–195° to …
