實驗內(nèi)容豐富多樣，包括了解金屬箔式應(yīng)變片的應(yīng)變效應(yīng)、電橋的工作原理，掌握單臂電橋、半橋、全橋的性能，并比較其靈敏度和非線性度。此外，學(xué)生還可以通過該設(shè)備自主設(shè)計電子秤系統(tǒng)，完成從理論到實踐的轉(zhuǎn)化。
在技術(shù)參數(shù)方面，該實驗儀配備了可調(diào)直流電壓源（0～12V連續(xù)可調(diào)，最大電流1A），以及多組對稱電源。電子秤傳感器的測量范圍為500g，內(nèi)置4組350Ω應(yīng)變片，能夠滿足基礎(chǔ)教學(xué)和實驗需求。此外，設(shè)備還提供了差動放大器模塊、電位器模塊、電阻模塊等多種實驗?zāi)K，方便學(xué)生進行多樣化的實驗設(shè)計。
English Introduction
The DH-SJ7 Strain Gauge Characteristics and Electronic Scale Design Experimental Instrument is an educational device introduced by Shuangxu Electronics, designed to help students gain a deep understanding of the working principles of strain gauges and their applications in electronic scale design. The device features a transparent modular design, with experimental components placed on a nine-hole board and then housed in a main case, effectively addressing issues of component fragility and management difficulties.
The experimental content is diverse, including understanding the strain effect of metal foil strain gauges and the working principles of Wheatstone bridges, as well as comparing the sensitivity and non-linearity of single-arm, half-bridge, and full-bridge configurations. Additionally, students can independently design an electronic scale system using this device, facilitating the transition from theory to practice.
In terms of technical specifications, the experimental instrument is equipped with an adjustable DC voltage source (0–12V continuously adjustable, with a maximum current of 1A) and multiple sets of symmetrical power supplies. The electronic scale sensor has a measurement range of 500g and includes four sets of 350Ω strain gauges, which can meet the basic requirements for teaching and experimentation. Moreover, the device provides various experimental modules, such as differential amplifier modules, potentiometer modules, and resistor modules, enabling students to design a wide range of experiments.
再置于整體機箱中，解決了實驗元件易損壞、不易管理的問題。各個型號包含了電學(xué)設(shè)計性、基本傳感器設(shè)計性、光電傳感器設(shè)計性、溫度傳感器設(shè)計性等實驗內(nèi)容可以相互拓展，也可根據(jù)客戶需要單獨搭配，而且學(xué)生能夠自行拓展實驗內(nèi)容，是本裝置的大特色，因此非常適合于物理基礎(chǔ)實驗教學(xué)。
基本傳感器型物理設(shè)計性實驗裝置采用分立的傳感器模塊及處理電路，主要由五部分組成：傳感器實驗臺、九孔板接口平臺、音頻振蕩器、直流恒壓源和處理電路模塊。
