This series of products fully comply with the GB/T228-2002 room temperature tensile test method standard for metallic materials.
The testing machine adopts high-precision spoke type sensors, microcomputer controls full digital broadband electro-hydraulic digital valves, drives precision hydraulic cylinders, performs automatic control of test force, displacement, deformation in multiple modes to complete the tensile compression of the sample , The bending test meets the requirements of the national GB/T228-2002 "Metallic Material Tensile Test Method at Room Temperature" other standard requirements.
The main machine of the testing machine adopts the hydraulic cylinder under-mounted type; the power transmission device for adjusting the test space is installed at the bottom of the testing machine, the transmission is stable: the upper lower jaw seats are fully open structure, automatic hydraulic tightening system, convenient sample clamping good stability.
Using a liquid crystal computer to complete the setting of test parameters, control of the test process, data acquisition, processing, analysis, storage display during the test (test data includes: material tensile strength, elastic modulus, elongation, yield strength, regulations Non-proportional extension strength, etc.) The control measurement are precise accurate.
Using high-precision amplifier 24 high-precision AD converter, effective internal code: ± 120000: test force resolution 1/120000
PID control is used to realize the constant speed control of the load. The speed range: 0.2-5%S/S has a load holding function.
PID control is adopted to realize the constant speed control of displacement, the speed range: 0.6-60m/min with displacement maintaining function.
PID control is adopted to realize constant speed control of strain. The speed range: 0.00025/S-0.0025/S has strain retention function.
