Product Description

SCW-300A Microcomputer Controlled Steel Strand Stress Relaxation Tester

    SCW-300A microcomputer controlled steel strand stress relaxation tester is a high-precision material testing equipment using servo control technology, computer data acquisition and processing, which can realize closed-loop control and automatic detection. It consists of test host, servo control system and measurement and control system. The test instrument consists of four parts, the maximum test force is 300kN, and the test machine accuracy level is better than level 1.
    SCW-300A microcomputer controlled steel strand stress relaxation tester is used for tensile stress relaxation test of prestressed steel wire, steel strand, PC steel bar and metal material; isothermal stress relaxation test; stress relaxation test period ≥1000h.
    The isothermal stress relaxation test is to maintain the sample at a given temperature (20 ° C ± 2 ° C), a certain length (L0 + △ L0), from the initial force F0, determine the change in force on the sample; stress relaxation test period 120h ~ 1000h can be set.
    Initial test force, initial test force hold, zero time to maintain initial total strain, constant gauge length, continuous recording of test force and temperature, timed test force and temperature, monitoring of initial total strain and gauge length, relaxation rate, relaxation characteristic curve (remaining Test force - temperature, force - relaxation rate, force - displacement deformation, etc.).
    Stress relaxation test time (start time, given time, recording force interval time, continuous recording, relaxation time ≥ 1000h).
