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: Is the 16 kilogram electric pressure gauge and the electric contact pressure meter the same?: The principle is the same, only one is the contact point, and the other is the electronic component.

Q: What does "MPa" on the pressure gauge mean?: The MPa (Zhao Pa) on the pressure gauge is the unit of pressure,0.1 MPa =1 kg / cm2.

Q: How to connect the household air conditioner pressure gauge?: Before adding snow to open air conditioning, after the external machine started, the table connected to air conditioning gas nozzle (to receive a relatively thick that housekeeper, air-conditioning pressure in general 2.8MPA

Q: What is the pressure gauge cock: Connecting device for pressure gauge and measuring body

Q: What are the thread connections of the pressure gauges?: Upstairs is indeed correct, these three are very common, usually may also have BSP and NPT and other standard interfaces, see which side, the company's internal standards as much as possible, convenient for maintenance

Q: What kind of valve does the pressure gauge valve belong to?: Pressure gauge valve is a special valve, from the valve structure, belonging to the needle valve.

Q: Pointer form of pressure gauge, with digital pressure meter, advantages and disadvantages?: Pointer gauges are mature

Q: Vacuum table refers to the vacuum or pressure gauge?: In fact, the vacuum meter, as the name suggests, is the reading of the vacuum. Here's a brief look at all the pressures:G P (table): pressure from pressure gauge read, it is the relative pressure by the atmospheric pressure as the benchmark value.Absolute pressure P (absolute): the actual pressure value based on absolute vacuum.The relationship between the absolute pressure gauge,P (absolute) =P (atmospheric pressure) +P (table)If the P (must) <P (atmospheric pressure), P (table) = - (P - P, the atmospheric pressure is lower than the vast) pressure gauge called vacuum. The higher the vacuum, the smaller the pressure.

Q: Y-100 what is the thread of the pressure gauge?: Y-100 is the ordinary 100 meter diameter of the pressure gauge, 100 table diameter thread interface, standard is M20*1.5.

Q: Note: 1 I asked not the difference between the diaphragm pressure gauge and the ordinary pressure gauge;2 what I ask is not the difference between the diaphragm pressure gauge and the diaphragm pressure gauge;I think someone has answered a similar question before, and when it comes to the diaphragm, it's driven by isolated liquid. What's that diaphragm? Or the diaphragm is the diaphragm that contacts the measuring medium: Diaphragm pressure gauge measuring element type is "spring pipe + diaphragm", the diaphragm is only isolated transmission components, rather than sensitive components; diaphragm pressure gauge directly to the diaphragm as a sensitive element, and no longer use spring tubeThe diaphragm meter by spring tube range limit, the minimum range is usually only 0.1MPa or 60kPa; diaphragm pressure meter is usually used for micro pressure, the minimum can be 1kPa to 2.5MPa. two, the highest range have overlapping and complement each other.
