Extensometer.
Background technique
Extensometer (extensometer) is a kind of instrument for measuring line deformation between component and other object two o'clocks, is led to
Often it is made of sensor, amplifier and logger three parts.Sensor is directly contacted with tested component.The two o'clock being tested on component
The distance between kg2kg2 be gauge length, the variation kg1kg2 (elongating or shortening) of gauge length is that line deforms.The deformation of member, sensor with
Deformation, and it is this deformation be converted to the information such as machinery, light, electricity, sound, amplifier puts the tiny signal that sensor exports
Greatly.Amplified signal is directly displayed or is automatically recorded by logger (or reader).
The fixation of existing extensometer and testee mostly uses rubber band to carry out.For example, when steel strand tensile tests,
It needs extensometer to be clamped steel strand wires, both ends snarl fixation with rubber band again.In general, power is probably in 270~280kN or so
Steel wire is broken, then manual operation need to be laid down by extensometer in 250~260kN or so, is done so just than relatively hazardous, and result
It is inaccurate.
