HK21B type of blind-hole method of residual stress detector Description
|
|
HK21B residual stress detector used blind-hole method to analysis and research the residual stress of variety materials and structures,it’s also be used as a stress analysis instrument to measure the structure in static strength researching and any point deformation of matieral.
|
|
It also can measure force, pressure, torque, displacement and temperature when it be equipped with appropriate sensors.
|
|
It can measure the measurement and direction of residual stress value directly when using the computer as a microprocessor and adopting high precision measuring amplifiers,data acquisition and processor and the measurements without zero,then realizing the automation of the residual stress measurement.
|
|
The main technial performance and indicators of HK21B blind-hole residual stress detector
|
|
Strain messurement rang: 0~±30000με
|
|
Stress measurement range: 0~±6000Mpa
|
|
Resolution: 1με
|
|
Resistance strain gauge application: 120Ω±0.5
|
|
The LED display the three directions’ strain value ε1,ε2 and ε3 as the stress rleasing during the measuring,it also display the calculated stress valueδ1 and δ2 and the principal stress direction angle θ, the showing way is swicth button mode.
|
|
This instrument is equipped with TP40 intelligent printer.it can print the three direction stress value,it also print the calculated residual stress valueδ1 and δ2,and the principal stress direction angleθ.
