Product Readme

Applications:
    This series of testing machine is mainly used to test the tensile strength、elastic modulus、tensile rate、σp0.2 of the strand. Assembled with clamp, this machine also could carry out compression, bend test on metal, metalloid and part. The testing machine is not only quite up to the requirement of the steel stranded wire stretching testing of GB/T 5224-2003 Prestressing concrete, suitable for strand stretching testing, but also quite up to the standard of GB/T 17671-1999, suitable for cement mortar resist compression、resist break testing, and satisfies with the standard of GB/T232-1999, suitable for bend test of metallic material(need to assemble with interrelated clamp).

Feature:
1.Using high-precision amplifier and A/D converter of 24 bits high precision, the testing machine   has effective code ±20000, so the measurement resolution can be one over two hundred thousand. If use high-precision load sensor which can ensure that the continuous measurement within the maximum test force of 0.4% ~ 100% will not step and the precision is also better than that of grade 1.
2.It adopts the servo valve group as control actuators, so it has strong anti-pollution ability.
3.The testing machine realizes the displacement of closed loop control by PID control strategy, which can realize the function of constant speed loading, load keeping and constant speed unloading
4.The testing machine realizes the displacement of closed loop control by PID control strategy, which can realize the control function of constant displacement and displacement keeping.
5.Experimental standard can be conveniently added and deleted and the control procedure can be edited freely according to the test requirements.
6.The machine can display testing curve in-timely, can choose the curve coordinate freely. Three curves can be displayed in one page at the same time, and may zoom in locally.
7.The testing machine adopts standard database to store the testing result and provides with data interface.
8.The testing machine adopts open excel statement. Users can choose Built-in statements or Custom reports.
