變形測量系統的變形放大器單元是電子萬能試驗機的主要組成部分之一,它的主要功能是把傳感器產生的微弱信號加以放大,處理后送到數顯表或者計算機,從而把試樣所承受的變形值記錄或顯示出來。
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.
現在大多數變形單元采用單芯片24位超低噪聲模數轉換器,此芯片集信號放大,A/D轉換于一身。由于本套變形單元具有“以單芯片為核心,外圍電路少”的特點,因此本系統具有精度高,穩定性能好,線性誤差小,抗干擾能力強等特點。合理的設計,良好的工藝布局使放大器穩定性極好。它與放大器相聯的單片計算機單元,作為主機的心臟,負責整機的放大器量程變換、數據采集、數據傳輸、試驗方式選擇及液晶顯示,直讀的數字量化,同時可以把這些數據通過RS232口輸出,通過RS232口也可以接受其它設備的指令。由于采用單片計算機控制,本單元具有自動調零的功能,調零時,只需在主界面按清零鍵即可全程自動清零,清零時間極短。
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 quantizationdirect 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 ofautomatic adjustment of zero, zero, only in the main interface to resetbutton can be full automatic reset, reset time is very short.
