Factors affecting the stability of deformation measurement of the test machine

Testing machineThe measurement is related to the accuracy of the test results and is the main link in the use of the test machine. Choosing test measurement instruments with high reliability and strong stability is an important factor worth considering by users. So let me take a look at it.Factors affecting the stability of deformation measurement of test machineWhat are:

The deformation measurement of the test machine is an important part of the test machine measurement and control system and is a key technical link of the test machine. The deformation amplifier unit of the deformation measurement system is one of the main components of the test machine. Its main function is to amplify the tiny signals generated by the sensor, and then send them to the digital display table or computer after disposal, so as to record or display the deformation values ​​accepted by the sample.

Reasonable design makes the amplifier extremely stable.Impact testing machineIts monolithic computer unit connected to the amplifier, as the heart of the host, serves as the amplifier range conversion, data acquisition, data transmission, experimental method selection and liquid crystal display of the entire machine, and can directly read digital quantization. At the same time, it can output these data through the RS232 port, which can also withstand instructions from other devices through the RS232 port. Due to the use of single-chip computer control, this unit has the function of automatic zeroing. When adjusting zeroing, you only need to press the clear key on the main interface to automatically clear the entire process, and the clearing time is extremely short.

The flexibility of the test machine deformation measurement - the flexibility indicator is related to the displacement rate of the measured change. Flexibility is a sign of weighing physical instruments. The more precise the flexibility of the test machine measurement system, the higher the accuracy of the measurement result.
