Compression testing machine

Load frame

1.    Compression space is adjusted by padding block

2.    Ergonomically designed load frames ensure safety, reduce operator fatigue, and provide the highest level of flexibility.

3.    "Quick Return" hydraulic valve for higher throughput

4.    Automatic limit checking for overload, over temperature, over voltage, etc.

5.    The system can return automatically, the oil cylinder can return the original position via manual or automatically after finishing testing

6.    Imported encoder mounted on the seat is for position measurement of piston with high accuracy

7.    Imported servo valve provides high stability and reliability

Load cell

1.     Built-in load cell is assembled inside the piston for direct measurement with high accuracy

2.     High precise load cell measures and captures sensitively tension and compression force, high accuracy load measurement resolution reaches 1/*****0 with no steps.

3.     American brand load cell ensures high precision and repeatability.

 

Controlling system – DTC***0

1.    Closed loop control of stress, strain and displacement.

Control loops can switch automatically and smoothly. Control algorithm adopts advanced neural element self-adapting PID. Neural element has ability of close to any non-linear function , simple structure and learning algorithm. It can adapt changing of control object by changing its own synapse weighting and distinguish parameter on line, rebuild object model on line.

2.    Control system based on DSP

DSP, the professional CPU and RISC, is used as control chip of the products. The chip has many functions, such as *0MIPS, **-digit fixed point, vector control, A/D exchange, position capturing , etc. It is a CPU widely used in industry controlling and suitable to be IC of our products.

3.    USB 1.1 communication

Data exchange between hardware and software via USB 1.1inrerface and velocity of *2Mb/s.USB is main direction of development of communication, which has merits of high communication velocity, variety of communication mode( such as controlling , breaking, batch, real time ,etc.), and will be the main mode of communication.

4.    Data acquisition system and position capturing system.

Data acquisition system consists of 8 channels of *4 bit A/D exchange; effective resolution is 1/*****0 with non-step in full range . Exchange velocity and gain are programmable on line. The products contain 3 channels of encoder position capturing system . permitting photo-electric orthogonal code impulse. Frequency can reach 5 MHZ, which has functions of correcting, direction identifying and number-counting.

Software - TestPilot

1.    Versatile, easy-to-use TestPilot software with A large and growing library of standards-compliant test methods (ASTM, ISO, DIN, EN, BS, and more)

2.    Modular design permits easy upgrading

3.    Formula define

1)     Plenty of test standards are built in the library of the software for routine tests.

2)     Users can define the formula in the standards library in order to meet special test procedures.

4.    User configured report

1)     User can preset report template and include necessary information, like company information, statistics, and etc.

2)     Test report can export to Excel

5.    Powerful graphic function

1)     Real time display curves, like displacement-load, stress-strain, displacement-time, load-times, and others

2)     Powerful analysis function can calculate typical value and display on the curve, like Fm, ReL, ReH, Rp.

6.    Measurement unit

1)    Users can select SI, or others, like N, kN, Kgf, lbf, Mpa, and so on

2)    Also user can define the unit by themselves using formula
