CMT2000 series microcomputer controlled electronic tensile testing machine is a new type of material testing machine combining electronic technology and mechanical transmission. It has a wide and accurate loading speed and force measurement range, and has high accuracy and measurement of load, deformation and displacement. Sensitivity, can also perform constant speed loading, constant speed deformation, constant speed displacement automatic control test, and has the function of low cycle load cycle, deformation cycle, displacement cycle.
This series of models are mainly suitable for testing non-metallic materials with a test load below 5kN.
The main function:
It is used for tensile, peeling, tearing and other tests of various non-metallic material samples, as well as special tests for some products.
1: Adopting a high-speed DSP platform, its high integration, powerful control, data processing capabilities, and high reliability are unmatched by testing machines using other processors.
2: Adopt a full-digital, closed-loop (force, deformation, displacement) control system based on the neuron adaptive PID algorithm, to realize full-digital closed-loop control of force and displacement, each control loop can be automatically switched, and realized when switching between modes Smooth transition without impact.
3: It can control and maintain the rate of test force and displacement.
4: Online identification of closed-loop control parameters.
5: High-precision 24Bit data acquisition system, high resolution, can be extended to 8 AD acquisition.
6: USB1.1 communication, communication rate is 12Mb / s, using full speed mode, batch transmission mode.
7: The system board adopts 4-layer PCB's unique anti-interference wiring method, which has strong anti-interference ability.
8: Except for the power supply interface, all other interfaces adopt standard USB-type interfaces, plug-and-play interface. This interface can be hot-plugged, that is, it has a plug-and-play function. Interface characteristics can be set online by software. Make the layout of each interface neat and reasonable, easy to plug.
9: The entire control system has high cost performance and high reliability.
10: The whole test process is controlled by microcomputer, and the load value, displacement value, deformation value, test speed and test curve are displayed dynamically in real time.
11: Data processing and analysis are performed by a microcomputer, and the test results can be automatically saved. After the test, the test curve can be recalled, and the test process can be reproduced by curve traversal, or curve comparison and curve enlargement can be performed.
12: The test software under the Chinese language Windows platform has strong data and graphic processing functions, and can print out complete test reports and test curves in real time.
13: Equipped with perfect limit protection, overload protection, emergency stop and other safety protection functions.
