Brief introduction: RD series microcomputer control electronic creep testing machine, is a new kind of testing machine equipped with full digital measurement control system. It fully meet GB/T2039 tensile creep durable test method and GB/T10120 "metal stress relaxation test method" requirement, for metal materials under high temperature or room temperature tensile creep, persistent, stress relaxation performance test. In addition, you can do the low cycle fatigue test and creep fatigue test. Quality testing machine is suitable for enterprises, research institutes of scientific research, colleges and universities teaching, etc. Features: 1. Driven by a digital servo system; 2. Using digital measuring system, overcome the analog circuit drift phenomenon; 3. The high measuring resolution, within the scope of the whole does not change, do not step; 4. The grating type, extensometer is of high precision and no drift; 5. A full digital control system is equipped with a large screen LCD screen and keyboard; 6. The computer system can real-time display test force, deformation and temperature curve; 7. A three-stage high temperature furnace temperature control by intelligent temperature controller, small temperature gradient and fluctuation; 8. Equipped with a UPS uninterruptible power supply, power remained constant power failure test. Technical indicators: The biggest test (kN) : 30 Effective load range (% FS) : 1 ~ 100 Force resolution: 1/200000 (within the scope of the whole does not change) Force value relative error (%) : + / - 1 Constant force control error (%) : + / - 1 Maximum deformation (mm) : 2, 5, 10, optional Effective measuring deformation range (% FS) : 1 ~ 100 Deformation resolution (microns) : 1 Deformation of the absolute error (microns) : 2 Constant deformation control error (microns) : 2 Test speed range (mm/min) : 0.1 ~ 50 Speed relative error value (%) : 0.5 mm Rod range (mm) : 150 Temperature range (℃) : 200 ~ 1100 (or 900 ~ 1200) Temperature fluctuations (℃) : plus or minus 2
