AT121 Series Ring Stiffness Tester

AT121 Series Ring Stiffness Tester

Description:

AT121 Series Ring Stiffness Tester with larger test space is specifically designed for plastic pipe ring stiffness testing. Equipped with suitable test grips and fixtures, it can address the needs of standardized and routine testing, providing the user high quality at the most affordable price. The dual column testing systems are suited for tension and/or compression applications with load range requirements from 30kN to 100kN. They are typically used for quality control and production testing.

Typical specimens: Plastic pipe, small components, reinforced plastics, metals, wire, composites, elastomers, wood products, textiles, biomaterials, paper products, adhesives, foam, consumer products

High Quality at affordable price

1) Pre-loaded ball screws and heavy duty bearings assure long life with zero backlash as well as linear low force and through zero performance. The result is accurate and repeatable measurements that truly represent the specimen characteristics rather than load frame deficiencies

2) Robust guidance columns increase lateral stiffness and ensure linear crosshead travel. This results in accurate crosshead alignment thus reducing variability in measurement data and producing better overall accuracy.

3) High-speed, low vibration, world-class, maintenance-free, Japanese made AC servo motor and servo controller

4) Photoelectrical encoder built in servo motor system is for position measurement of crosshead

5) Non-clutched drives, rated for full speed at maximum force

6) Built-in bidirectional load cell is assembled in the middle crosshead to prevent any collisions and simple to perform compression or tension tests

7) Dual action over-travel limits on all frames provide the highest level of safety and meet all international standards

8) Remote control keypad facilitates test operation

9) DTC-350 controller provides high speed data acquisition with 8-CH A/D converting

10) Full one-year warranty on parts and labor

11) Free software upgrading

Full complement of test accessories

Extensive range of accessories to meet test requirements in almost any application or industry: Plastics, metals, biomedical, composites, elastomers, components, automotive, aerospace, textiles, and more.

Controlling system

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 40MIPS, 32-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 12MB/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 24 bit A/D exchange; Effective resolution is 1/350000 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.
