AC5直流檢流計(jì)/AC-5
AC5直流檢流計(jì)的產(chǎn)品介紹
AC5系列直流檢流計(jì)是一種高靈敏度的磁電式指針儀表，專為測(cè)量微弱直流電流和電壓而設(shè)計(jì)。該系列產(chǎn)品采用精密張絲懸掛結(jié)構(gòu)，通過(guò)載流線圈在磁場(chǎng)中的偏轉(zhuǎn)實(shí)現(xiàn)高精度測(cè)量，適用于科研單位、學(xué)校實(shí)驗(yàn)室及電工測(cè)試場(chǎng)景。其核心特點(diǎn)包括便攜式設(shè)計(jì)、密封式膠木外殼保護(hù)測(cè)量機(jī)構(gòu)免受污染，以及水平放置時(shí)良好的抗傾斜性能。AC5檢流計(jì)可提供多種量程選擇（如±10μA至±300μA），內(nèi)阻為50Ω，能有效檢測(cè)低至10⁻¹⁰A的微弱電流或10⁻⁶V的微小電壓，廣泛應(yīng)用于光電流、溫差電動(dòng)勢(shì)等信號(hào)的測(cè)量。儀表配備機(jī)械調(diào)零和電氣調(diào)零功能，并設(shè)有粗測(cè)、細(xì)測(cè)及短路按鈕，便于操作和信號(hào)保護(hù)。其雙向偏轉(zhuǎn)表頭設(shè)計(jì)可直觀顯示電流方向，雙分度標(biāo)尺確保讀數(shù)清晰。147
AC5 Galvanometer Product Introduction
The AC5 series DC galvanometer is a highly sensitive magnetoelectric pointer instrument designed for measuring微弱直流電流（DC microcurrents）and voltages. Featuring a precision taut-band suspension system, it utilizes the deflection of a current-carrying coil within a magnetic field to achieve accurate measurements, making it ideal for research institutions, educational laboratories, and electrical testing environments. Key features include a portable design, sealed bakelite casing to protect internal components from contaminants, and stable performance even with slight tilting. With multiple ranges (e.g., ±10μA to ±300μA) and an internal resistance of 50Ω, it can detect currents as low as 10⁻¹⁰A or voltages of 10⁻⁶V, suitable for applications like photocurrent and thermoelectric potential measurement. The device incorporates mechanical and electrical zero-adjustment mechanisms, along with coarse/fine measurement buttons and a short-circuit function for operational flexibility and signal protection. Its center-zero bidirectional scale and dual graduations ensure clear readability. 2518
技術(shù)原理與結(jié)構(gòu)特點(diǎn)
AC5檢流計(jì)基于載流線圈在永磁場(chǎng)中受力矩偏轉(zhuǎn)的原理工作，采用極細(xì)金屬懸絲替代傳統(tǒng)軸承，顯著降低摩擦阻力，提升靈敏度。儀表結(jié)構(gòu)包含寬頻表頭、放大電路及防護(hù)外殼，支持機(jī)械/電氣雙重調(diào)零。其輸入阻抗低，適合準(zhǔn)四端電阻信號(hào)接入，避免靜電干擾。分檔量程覆蓋嚴(yán)謹(jǐn)（如AC5-1至AC5-7型號(hào)），可通過(guò)開(kāi)關(guān)轉(zhuǎn)換實(shí)現(xiàn)量程切換，確保測(cè)量連續(xù)性。表頭設(shè)計(jì)兼顧標(biāo)量與矢量顯示需求，±60/±50格分度便于觀察微小變化。41821
Applications and Functional Advantages
The AC5 galvanometer excels in zero-balance detection for DC bridges and potentiometers, while its high sensitivity enables direct measurement of nanoampere-level currents in fields such as biophysics (e.g., nerve action potential recording) and material science. The instrument’s modular design allows seamless integration with external circuits via input terminals, and its damping time is optimized for rapid stabilization. Users can manually adjust the mechanical zero point with a dial or fine-tune electrical zero via a multi-turn potentiometer. The sealed construction ensures long-term reliability in diverse environmental conditions. 3629
