Computer Control 30/50/100kn Plastic Pipe Ring Stiffness Tester¹

Product Description Ring stiffness testerOverviewThis tester is used to determine the ring stiffness, compression, ring softness of thermoplastic pipes having circular cross-section. It conforms to the requirement of all kinds of plastic pipes, structured-wall pipes, PE corrugated pipes, helically wound pipes etc.StandardsISO 9967, ISO 9969, ASTMD 2412 and the equivalent.Characters1.Double-column high rigidity structure,wide range of speed control2.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 &direct.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. 6.Multi protection functions from mechanical & electrical design and software, including over-load, over-current and over-temperature.TypeJJRST-1411JJRST-1412Max.load30kN(50kN,100kN option)Accuracy grade0.5Load resolution1NLoad accuracy±0.5%Crossbeam resolution0.001mmCrossbeam accuracy±0.5%Crossbeam speed0.5mn-200mm/minSpeed Accuracy±1%Pipe diameter range110mm-2000mm110mm-3000mPipe scope for inner diameter measuring system200mm-2000mm200mm-2000mmAccuracy of inner diameter measuring system±1%Specimen width1000mmPower supply220(1-15%)VAC-220(1+10%)VAC50Hz 2.0KwDimension(L*W*H)(650*1360*3400)mm(650*1360*4300)mmWeight600kg700kgCreep Ratio Test(option)Constant load accuracy±1%Timing range1-9999h59min59sTiming resolution1sTiming eror0.1‰s
