Servo-Hydraulic Compression Testing Machine (type B) Compression Test Machine 2000kn

Servo-hydraulic Compression Testing Machine (type B)  Compression test machine 2000KN

Capacity: 2000kN

Functions:
This series of compression testing machine is widely used for compression strength determination of cement, concrete and rock. Equipped with optional fixtures and measurement devices, it can be used for concrete splitting tensile test, flexure test.

Standards:
BS EN 12930.4, ASTM C39, GB/T 50081(Part 6)

Features:
Load frame
1. One-body casting frame with high stiffness
2. Upper compression platen is adjusted by motor to satisfy various test space
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
L Built-in load cell is assembled inside the piston for direct measurement with high accuracy
L High precise load cell measures and captures sensitively tension and compression force, high accuracy load measurement resolution reaches 1/350000 with no steps.
L American brand load cell ensures high precision and repeatability.

Controlling system DTC-500
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 2.0 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 1/500000 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
Two steps to start testing: Select a project, press start
This software features a large, growing host of pre-packaged test methods to help you quickly and efficiently meet the requirements of global test standards such as ASTM, ISO, DIN, EN, BS, and more. Selected by an operator at runtime, these methods are crafted to meet the specific test flow, analysis and reporting requirements of industry standards across a range of specimen and test types. Pre-packaged test methods are available in a wide selection of bundled sets, including: Polymers & Plastics, Metals, Construction Materials, Biomedical Products, Paper Products, Adhesives, foam, textiles and more.
