Micro-computer control electro-hydraulic servo compression testing machine CTM - YAW-2000

Micro-computer control electro-hydraulic servo compression testing machine CTM

1. Usage

The serial compression testing machines CTM are mainly used in the project construction such as the railroad, road, bridge, port, high-rise etc. This tester is mainly used for the bending and breaking resistant pressure test to the cement, sand, concrete, building material products, and other materials.

2.Test force safety apparatus:

the electric motor stops when the temperature raises over the set value if the test force is 2%-5% higher than the max. test force of every level, or the output of the transducer reaches to the highest, because of the thermorelay on the electric plate.

3. Charateristics

This machine adopts the high precision electro-hydraulic digital servo valve for controlling the loading with the functions of automatic and manual loading. It finishes the complete test automatically controlled by a micro-computer according to the stress rate and preset curve. It has the function of dynamic displaying the speed, time and test curve.

4. Operating system

The system adopts the high precision digital servo valve. It is with the function of force closed-loop control. It fulfills the equal load rate loading and equal stress rate loading. It is with the high control accuracy and good reliability, fully conformed with the standards of GB, SIO, ASM, and so on. Also the test request of material, such as cement, concrete, etc, especially for the test place of long time continue operating.
