Bolt Tension Monitor
Use of Extensometer to Measure Bolt Elongation/Load During Torquing
An extensometer is a device used in bolt testing to accurately measure the elongation (stretch) of a bolt under load. It helps determine how much the bolt deforms when a tensile force is applied, which is crucial for assessing its mechanical properties like yield strength and ultimate tensile strength.
Bolt tension meter
-
Elongation: Change in length (inches or millimeters)
-
Load: Force applied (pounds KIP or megapascals MPa)
-
Stress: Force per unit area (inches per inch or millimeters per millimeter)
-
%Strain: Ratio of elongation to effective length
