Introduction to deformation measurement of electronic universal test machine

The deformation amplifier unit of the deformation measurement system isElectronic universal testing machineOne of the main components of the tester, its main function is to amplify the weak signals generated by the sensor, process them and send them to a digital display table or computer, so as to record or display the deformation values ​​suffered by the sample.

Deformation amplifier unit deformation measurement system is one of the main part of electronic universal testing machine, its main function is to amplify the weak signal produced by the sensor, after processing todigital meter or computer, thus the deformation of specimen withstandvalue recorded or displayed.

Most deformation units now use a single-chip 24-bit ultra-low noise analog-to-digital converter, which combines signal amplification and A/D conversion. Since this set of deformation units has the characteristics of "a single chip as the core and few peripheral circuits", this system has the characteristics of high accuracy, good stability, small linear error, and strong anti-interference ability. Reasonable design and good process layout make the amplifier extremely stable. Its monolithic computer unit connected to the amplifier, as the heart of the host, is responsible for the amplifier range conversion, data acquisition, data transmission, test method selection and liquid crystal display of the entire machine, and the digital quantization of direct reading. At the same time, these data can be output through the RS232 port, and instructions from other devices can also be accepted through the RS232 port. Due to the use of single-chip computer control, this unit has the function of automatically zeroing. When 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.

Now most deformation unit with single chip 24 bit ultra low noise analog to digital converter, this chip set signal amplification, A/D conversion in a body. Because the set of deformation unit has a "take the single chip as the core, features less peripheral circuit", so the system has high precision, stable performance, linear error is small, anti-interference ability and other characteristics. Reasonable design, process layoutgood makes the amplifier with excellent stability. Single chip computer unit it and amplifier connected, as the host of the heart, responsible for the amplifier range conversion, data acquisition, data transmission, testmethods and the choice of liquid crystal display, digital quantization direct reading, also can put these data output through the RS232 port,through the RS232 port can also accept other equipment. Due to the use of single chip computer control, the unit has the function of automatic adjustment of zero, zero, only in the main interface to resetbutton can be full automatic reset, reset time is very short.
