Features and uses: the TLS-QZD2000 series microcomputer control spring tension and compression testing machine is a new generation of the spring testing instruments, the aircraft originality gantry structure, testing machine more stable, more reasonable structure, higher accuracy, using high-speed can be stored approaching slow acquisition, improve test accuracy, and ensure the efficiency of the test; regardless block measuring test force, expanded the range of precision test; This machine can automatically detect speed six test points, and automatically returns to its original position; different class file, to be called at any time; load sensor for automatic correction; aircraft also has a peak hold, overload protection, displacement and test force is automatically cleared, stiffness calculation, the initial tension calculation, data query, data printing. It is applied to a variety of precision tensile and compression coil spring testing and the testing of brittle materials. Same type can replace imported products. Technical Specifications: 1, the maximum test force: 2000N2, accurate measurement of test force range: 80 N to 2000N; 3 test force minimum reading value: 0.1N4 displacement of the minimum reading value: 0.01mm; Displacement accuracy: ≤ ± (50 +0.15) um6 loading speed: 0mm/min 500mm/min (stepless speed regulation and arbitrary in this range can be set); 7, tensile test between the two hooks maximum distance: 450mm8, compression test between the two hooks distance: 450mm9, tensile and compression tests stroke: the diameter: Ф100mm11 on 450mm10 upper and lower platens, Power: (must have reliable grounding) 220V ± 10% 50Hz12 working environment: room temperature 10 to 35 ° C, humidity 20% ~ 80 % Contact: 4000531334 Mobile: 15098932921 Fax 0531 -87,163,432 Website: www.jnjsf17.com
