JJ-TEST RING STIFFNESS TESTER FOR PLASTIC PIPES0 pages

■ JJRST Series Ring Stiffness Tester

The tester is used to determine ring stiffness, ring softness and compression of thermoplastic pies

having circular cross-section. It conforms to the requirements of all kinds of plastic pipes, such as

structured-wall pipes, PE corrugated pipes, helically wound pipes, etc.

•STANDARDS

1.Double-column high rigidity structure, wide range of speed control

2.Advanced closed-loop AC servo control system enables to increase the controlling accuracy and

stability. High resolution AD sampling circuit is introduced to collect testing datum , even the peak value

will not be lost.

3.Two/Four sensors are connected in a bridge way to strengthen the deflection resist of big pipes, also

reduce mangling rate of load sensor.

4. Unique design of inner diameter measuring system makes specimen easy to install and measurement

correct Sdirect.

5.Connect the tester to PC via RS232 to control test and download the test data, PC software may

realize the functions of test data storage, statistics, analysis and test results printout. Creep test also can

be realized (optional).

6 Multi protection functions from mechanical & electrical design and software, including over-load,

over-current and over-temperature.
