Shanghai Xiangjie tells customers how to choose electronic tension machine
The maximum load required depends on the type of material being tested and is one of the important issues to consider when deciding whether to choose a single-column or a gantry. Also consider whether you need an environmental compartment that is tested at a controlled temperature. The gantry is taller, allowing larger specimens and larger heating cabinets to be inserted between the struts. If you are going to do any compression testing on the foam, because the specimens tend to be large, a door device is generally required.
The door instrument is harder, so the deflection is one-half of the one-arm during the test. The last is the difference in cost. The price of a single-column electronic tension machine may be only 20,000-30,000 yuan, while the door style usually ranges from 30,000 to 60,000 yuan. These prices are just instruments. The computer type requires the cost of the computer, and the fixture is another separate cost, as is the installation and training. If a special temperature heating chamber is required, it is generally priced between 8,000 and 20,000 yuan.
Progress on electronic tensile machine software
The design of the electronic tensile machine in electromechanical is relatively mature. The new development is on the control software. Advanced computer software provides greater productivity and precision and is easier to use. These softwares have increased a certain degree of repeatability, something that has never been seen before.
For high-end users engaged in research, you can't just rely on readings at the breakpoint. Researchers can now use physical testing to find out what happened. Did the material stretch or deform before breaking? Is its deformation proportional to stress? The answers can help them evaluate materials, determine safety margins, and better simulate end use. For general businesses, this data is not required.
New computer software automates testing, data collection, analysis, report output, data storage and recovery. The user can operate the instrument at a certain load rate and the system will automatically adjust the speed of the beam. The new software also allows the user to obtain the true value of the tension during the test through the position sensor. The sensor accurately measures the distance the beam has moved. The automatic strain results are obtained by dividing the length of the sample by its original length. The new software also enables automatic verification and calibration of the load cell when the sensor is replaced. It "reads" the electronic components on the load cell and establishes parameters that eliminate the need for mechanical corrections that were previously done by the operator.
Newer software with faster data acquisition can more accurately capture load peaks and examine tensile/strain curves in more detail at higher speeds or when load fluctuations occur. Typical data acquisition speeds are approximately 50 Hz (50 readings per second), although sampling rates can reach 5 kHz.

The latest-powered electronic tensioners are cheaper than those with digital control panels that have been used for more than 10 years. The new computer has a simpler control and often does not require a digital display with a chart reading. Microcomputer-based electronic tensioners now drive the entire operation, reducing costs by eliminating the need for digital displays and electronic components.
