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 kind of oil is it in the oil filled pressure gauge?
- Pressure meter which is filled with glycerin or silicone oil, and other can not, the general manufacturers are full of glycerol, because glycerol is cheaper, but the temperature of glycerol is relatively large, good point is filled with silicone oil.
- Q: What's the pressure gauge in the snow?!
- Read the inner layer of the black circle. If you want to know which circle to read, just understand the meaning of each circle. The numbers in the red circle generally indicate the temperature (Celsius), and there are two red units. I can't see clearly. Now the reading is 58psi 14.5psi=1, a standard atmospheric pressure =0.1 MPa =1Bar, this is the conversion of various pressure relationship, that is now low pressure air conditioning system was 0.4 MPa, basically in the standard range.
- Q: What is the state of the warranty period for the ordinary pressure gauge?
- State regulations are one yearBelong to the scope of strong inspection, according to the requirements of 3 months of inspection, semi annual inspection, an annual inspection.To examine the range of inspection catalogue of Qiang Zha
- Q: How do remote pressure gauges receive frequency conversion?
- This is unable to access and control the frequency converter. The remote pressure gauge (resistance output) should be adopted - PG control board or pressure controller (resistance input / voltage output) - frequency converter (selection frequency, external control / voltage input)
- Q: How do you test the pressure gauge for the pressure vessel?
- Each unit has the relevant provisions of the inspection of measuring instruments. The pressure gauge is a strong inspection instrument, which must be inspected once a year (possibly half a year). To the qualified inspection unit to test, is the firm certificate. Note the work smoothly.
- Q: What is the maximum working pressure 6Mpa? How much do you want to fit the pressure gauge?
- Select 0-10MP.The pressure gauge is usually 1/3-1/2 larger than the maximum working pressure. When the pressure fluctuates greatly, 2-3 times of the rated working pressure should be chosen.The reason for this selection is that:1 keep the measurement indication clear;2. Head work in non limit state, reduce head mechanical fatigue, extend service life;3. Prevent peak work pressure damage meter.
- Q: Can you use the precision pressure gauge of level 0.25, measuring range (0~10) and MPa to verify the general pressure gauge of level 1, measuring range (0~6) MPa? Why?
- Yes, measurement pressure gauge inspection requirements, standard table accuracy requirements greater than or equal to 4 times
- Q: Why is the manifold pressure gauge called the manifold pressure gauge, not the air conditioning pressure gauge group?
- Manifold pressure gauge, "with the meaning of manifold"Why not air conditioning pressure gauge group, is the habit, the public, there is no reason.
- Q: 11 kw frequency conversion, plus an electric contact pressure meter to control a water pump motor. It requires low 4 pressure, high point and 8 pressure. How can I connect it?. Manufacturers to the approach of water pump to low-end wine began to maintain pressure, but not rising in opposition, the motor does not stop, what is the reason?. Also, I bought the electric contact pressure meter, there are 4 terminals, red at the bottom of the electrical contact, green in the middle, yellow in the above, the producer said I received the wrong end of the public, but I have three lines have been inverted. The motor is not automatic stop, master pointing what happened
- 1, since there are four terminals, it must have two is the power and ground, the other two are respectively corresponding with the output of high pressure and low pressure, general public is of course, so please make sure the power and ground, determined after measuring current and which is communicated with the. For less than 4 indicating pressure, another is the 8 high pressure, this is my guess, please implement this situation with the manufacturers.2, if you use a universal inverter, then when less than 4 pressure points, the inverter has to start the signal, until the 8 pressure point to arrive, you must slow down the frequency converter parking. At this point the pressure will gradually decrease and start the inverter when less than 4. Visible, below the 4 pressure point, the inverter must start, 8 down to the 4 stage, the inverter does not run until the pressure is less than 4, then trigger the start frequency converter3, frequency converter (non trigger level, the inverter has the function), 4 pressure points and start command series, 8 pressure points and stop command series, starting terminal and multi function terminal respectively contact transducer (multi function terminal need programming, three line mode, the brand names are
- Q: Measurement data, installed in the normal position, do not know whether to reverse installation, please professionals to help answer! Thank you Urgently!
- Yes, the location does not affect the accuracy of the data
