Factors affecting the performance of electronic universal testing machines

Electronic universal testing machineCurrently, it is widely used, and what factors affect the performance of electronic universal testing machines? The following is a summary of several aspects:

1. The force value sensor of the electronic universal test machine. The quality of the sensor of the electronic universal test machine directly determines the accuracy and force stability of the test electronic universal test machine. Nowadays, the sensors used in electronic universal testing machines on the market generally use S-type sensors with small force values, and wheel-type sensors are used. The sensor is usually a resistive strain gauge type. If the strain gauge accuracy is not high or the glue used for fixed strain gauge is poor in anti-aging ability, it will affect the accuracy and service life of the sensor.
2. If the ball screw drives the sensor movement, if there is a gap in the screw, the test data produced in the future will directly affect the deformation and elongation after breaking. Some of the screws of the electronic universal testing machines on the market now use T-shaped ordinary screws, and such ordinary screws have a large gap and high friction, which will lead to a lifespan. Therefore, you must choose a high-quality screw.
3. The transmission system of electronic universal testing machines. Now, the transmission system of electronic universal testing machines on the market must not use a reducer or an ordinary belt, but both methods have this disadvantage: the former requires regular lubricating oil, while the latter cannot ensure the synchronization of the transmission, which affects the test results. Therefore, when purchasing an electronic universal testing machine, you should pay attention to weighing and choosing.
