Ⅰ、Main functions


  This machine is applicable for tensile,compression, bending, shearing, peeling and tearing test of metal materials and non-metal materials.They may add test methods or rules  of other materials to customers
’need . They are essential testing instrument for quality testing section, university and colleges, research institution and industrial and mining enterprise.


Ⅱ、Product features


  This machine adopts the most advanced and reliable console model constructer, imported whole digital alternating servo motor and servo adjustment system, imported load sens and photoelectric encoder. Whole digital measurement and control system can realize high precision, wide range measure and three closed loops control. The system of measure and control adopts high precision transducer, imported high quality electron device and whole digit design. And the card also complies with PCI2.1 and automatically distributes resources. Integrated double channels precision amplifier can automatically zero. Build-in large scale CPLD can program logistic chips, high speed operate and real time process. The whole digital control adjustment and demarcation can supply Single AD software interface. The software adopts blocking design, has many kinds of controlling means such as displacement, force, deformation, (stress and strain) metal tension and so on. Multistep control procedure can be compiled using program editor of the software by ourselves. We can analysis and process the testing data according to corresponding standards, and automatically finger out routine data, such as tensile strength, yield strength, modulus of elasticity, non-proportional extend strengthRP0.2, etc. Batch program of the software can sum up and compare the result and curve of one batch of specimen. The testing data adopts database management, supply word Exel and self-defining progra and meet with the special requirements. Flexible editing mode of report forms can print satisfied table.

Q: What does the pressure gauge "radial back" and "axial front" mean? What's the side of the ordinary pressure gauge?
This is basically with the installation board, convenient installation and fixed
Q: How is the pressure gauge ABC divided?
Pressure gauges belong to the category of safety protection, which belong to strong inspection items. According to the JJG52-1999 test procedure, the cycle is half a year.Enterprises may, according to the specific circumstances used, determine the test cycle by A/B/C.Class A is compulsory test, which is related to production safety and environmental monitoring. The test cycle must be only less than half a year according to the verification regulations. If the conditions are bad, the verification cycle must be shorter.The B class should in principle not exceed the requirements specified in the verification regulations.The C class can determine the cycle of verification according to the characteristics of the enterprise, but there should be a square for determining the period of verification
Q: The difference between yn and YTN pressure gauges
Seismic pressure gauge models now there is no unified naming rules, general provisions are: Y: T: pressure gauge; spring tube; N: Seismic
Q: How about the model of seismic pressure gauge?
There is a general proof letter "N"
Q: How to determine the accuracy level of a pressure gauge?
The accuracy levels of the precision pressure gauges are 0.1, 0.16, 0.25 and 0.4 respectively. The accuracy levels of the general pressure gauges are 1, 1.6, 2.5 and 4 respectively. The method of selecting the accuracy level of the pressure gauge shall be based on the requirements of the production process, economic, practical and testing methods, and the accuracy grade shall be determined according to the allowable error of the minimum pressure measured. Precision class calculation method: the actual error value / actual range * 100% out of the figures, remove the number, get the number close to the above numerical value, the accuracy level is how much
Q: What is the range of use of a pressure gauge? Why is it at its measuring range of 1/3-2/3?
Pressure gauges are common range instruments, the statutory use of membrane pressure gauges should be used. (2) when the pressure of the pressure is stable, the normal operating pressure shall be at 1/3 2/3, 2 of the upper limit of the measuring range of the instrument
Q: Why does the internal surface of the pressure gauge contain oil?
The utility model has the function of shock proof, and the pressure gauge with silicon oil is a shockproof pressure gauge.Silicone oil is often used as high grade lubricating oil, shockproof oil, insulating oil, defoaming agent, release agent, polishing agent and vacuum diffusion pump oil, etc.. Among the various silicone oils, methyl silicone oil is most widely used and is the most important kind of silicone oil, followed by methyl phenyl silicone oil. In addition, there are ethyl silicone oil, methyl phenyl silicone oil, nitrile silicone oil and so on. Various functional silicone oils and modified silicone oils are mainly used for special purposes.
Q: How do you see a vacuum gauge?
The pressure on him is 0. 1 stands for 1MP
Q: What is the actual size of the pressure gauge nozzle G1/2?
G stands for non threaded cylindrical pipe threadsTooth angle: 55 degrees: G1/2-LH (left, right, wrong)Size code, number of teeth per inch, diameter, middle diameter, path1/8 289.728, 9.147, 8.5661/4 1913.157, 12.301, 11.4453/8 1916.662, 15.806, 14.951/2 1420.955, 19.793, 18.6313/4 1426.441, 25.279, 24.11711133.249, 31.77, 30.29111/4 1141.91, 40.431, 38.95211/2 1147.803, 46.324, 44.845
Q: Excuse me, where can I check the pressure gauge in Chongqing?
Local metrology Bureau, if you know, manufacturers can also be tested
