Factors that determine the test accuracy of Hengsi Shanda Electronic Universal Testing Machine

Friendly tips for Jinan Hengsi Shanda Instruments: BuyElectronic universal testing machineYou should find a suitable product needs. Before purchasing an electronic universal testing machine, we should figure out the determinants of their performance and accuracy, as well as its purpose, so that the product can be tested correctly. What are the specific factors?

1. Selection of sensors for electronic universal testing machines
The quality of the electronic universal tester sensor determines the accuracy and strength stability of the tester. Nowadays, electronic universal tester generally uses S-type sensors, and those with high force values ​​generally do not use S-type. The internal resistance of the sensor should be more important. Its quality determines the service life and linearity of the sensor accuracy, so imported high-precision sensors should be used. The higher the accuracy of the sensor, the better the linearity, and the better the performance.
2. The ball screws of electronic universal testing machines must be free of gaps. If not, it will affect the test results. T-shaped ordinary screws are generally used on the market. The service life of this ordinary screw will generally be relatively short. Imported ball screws should be used, which has a long service life and accurate accuracy.
3. The transmission system of the electronic universal test machine
There are two common transmission systems of electronic universal testing machines: one is a reducer and the other is an ordinary belt. These two methods have certain disadvantages, such as adding lubricant frequently. The poor synchronization will affect the results of the test. The electronic universal testing machine of Jinan Hengsi Shanda Instrument Company uses a full-arc synchronous belt to decelerate, with high test accuracy, high efficiency, long service life, low maintenance cost and low noise.
4. Motor of electronic universal testing machine
There are many types of motors for electronic universal testing machines:
The control speeds of three-phase motors, variable frequency motors and these two motors are relatively slow and inaccurate. Hengsi Shanda Instruments use servo motors from Japan Panasonic. The control method adopts full digital pulse control, with a wide speed regulation range, accurate control positioning, and fast reaction. This motor can ensure accurate speed control and long service life. 5. Software and hardware of electronic universal testing machine. Our company uses the world's most advanced 32-bit controller, and the program runs smoothly.
