Product Description

 

Products Specifications:

Steel strand stress Relaxation Testing Machine

This machine is used to test the tensile stress relaxation strength of pre-stressed steel strand, rebar under normal temperature. 

 

Features 

Four column rigidness frame structure, horizontal type, the screw rod adjust the puller to move, stepless loading speed regulation

Close-loop servo control, servo motor and driver combine with the high precision sensor, achieves high precision, wide range.

Test rate controlled by servo motor and speed regulator, integrates overcurrent, overvoltage, overload protection, smooth loading, lower noise

Graphical display relations between residue test load against time, relaxation rate against time, temperature against time

Can calculate the stress relaxation performance of objects in coming 1000hours 

Automatic calculate the stress relaxation performance and print test report

Digital calibration for load and displacement 

Test data storage, inquiry, review
