Four point bending tester DR-6001
 
Main functions:
 
It is used for tensile, compression, bending, shearing, peeling, tearing and other tests of various metal and non-metallic material samples, as well as special tests of some products.
 
Main features:
 
1: With high-speed DSP platform, its high integration, powerful control, data processing ability, and high reliability are unmatched by other processors.
 
2: The full digital, three closed loop (force, deformation, displacement) control system based on neuron adaptive PID algorithm is adopted to realize the full digital, three closed loop control of force, deformation, displacement. Each control loop can be automatically switched, and the smooth transition without impact can be achieved when switching between modes.
 
3: It can control and maintain the test force, deformation, displacement and other rates.
 
4: Online identification of closed-loop control parameters.
 
5: High precision 24Bit data acquisition system, with high resolution, can be expanded to 8-channel AD acquisition.
 
　　6：USB1。 1. Communication, with the communication rate of 12Mb/s, adopts full speed mode and batch transmission mode.
 
7: The system board adopts the unique anti-interference wiring method of 4-layer PCB, with strong anti-interference ability.
 
8: Except for the power interface, all other interfaces adopt the standard USB interface. Plug and play interface This interface can realize hot plug, that is, it has the plug and play function. Interface characteristics can be set online by software. The layout of each interface is neat and reasonable, and it is convenient to plug and unplug.
 
9: The whole 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: The microcomputer is used for data processing and analysis, and the test results can be saved automatically. After the test, the test curve can be recalled, and the test process can be reproduced through curve traversal, or curve comparison and curve amplification can be performed.
 
12: The test software under Windows platform in full Chinese has strong data and graphics processing functions, and can print complete test reports and test curves in real time.
 
13: It has perfect safety protection functions such as limit protection, overload protection and emergency stop.
