PIT-D Charpy impact

ModelPIT752D-2(LCD type),PIT752D-3(computer type),PIT752D-4(instrumented type)

Maximum energy750J (optional 300J,450J,600J)

Function

This machine is used for measuring the Charpy impact resistance of metal and other materials.

Features:

1.      One-body cast frame design of seat and column provide high stability and rigidity

2.      Front and rear columns are symmetrical. Pendulum arm is designed of cantilever beam support, with simple structure and high machined precision

3.      Apply high precision bearing with small friction. Absorbing energy without loading is less than 0.3%

4.      Double reduction gear system replaces old style drive system with high efficiency and avoiding transmission failure

5.      Round pendulum head design reduces windage losses to the most

6.      High rigid pendulum arm prevents axial and transverse vibrations

7.      Exchangeable pendulum is simple to change to satisfy impact energy of 300J, 450J, 600J, 750J

8.      Electromagnetic release of pendulum hammer

9.      Electromagnetic clutch for braking the pendulum and lifting to it to its initial position. A damper is equipped to prevent strong bump when clutching

10.    Full-closed enclosure with high safety

11.    Apply industrial PLC to control pendulum, and high precision rotary encoder to measure striker real time position. The whole system is stable, reliable and accurate

12.    A mini LCD monitor may real-time displays striker angle, impact energy, toughness, and other parameters. User can input specimen data and other information such as company information into this monitor. When connected to a printer, user input information and test results will be printed

13.    Optional computer with software control is available to realize semiautomatic operation. Operator only need charge specimens. Others can be controlled by software

14.    Optional specimen feeding system is available. Combined with computer and software, fully automatic operation can be realized

15.    Optional cooling chamber is available to satisfy cold specimen test down to -100℃
