BC7-1飽和標(biāo)準(zhǔn)電池/BC71
BC7-1飽和標(biāo)準(zhǔn)電池產(chǎn)品概述
BC7-1飽和標(biāo)準(zhǔn)電池是一種高精度電動(dòng)勢(shì)參考源，廣泛應(yīng)用于電壓校準(zhǔn)、精密儀器配套及實(shí)驗(yàn)室測量領(lǐng)域。其正極采用硫酸亞汞/汞電極，負(fù)極為鎘汞齊，電解液為硫酸鎘飽和水溶液，確保電動(dòng)勢(shì)長期穩(wěn)定性。該電池在1.01855～1.01868V范圍內(nèi)提供精確電壓輸出，年變化量小于100μV，適應(yīng)溫度變化后能快速恢復(fù)性能。設(shè)計(jì)上注重防震動(dòng)、防側(cè)放，建議在平穩(wěn)環(huán)境中使用以延長壽命。產(chǎn)品外形尺寸為96×24×24mm，便于集成到便攜式儀器中，如直流電位差計(jì)、數(shù)字電壓表等。1515
BC7-1 Saturated Standard Cell Product Introduction
The BC7-1 saturated standard cell is a high-precision electromotive force reference device, designed for voltage calibration and scientific instrumentation. It features a mercurous sulfate/mercury positive electrode and cadmium amalgam negative electrode, with saturated cadmium sulfate electrolyte to maintain stable output. The cell delivers a consistent voltage range of 1.01855–1.01868V, with minimal annual drift (<100μV) and robust performance under thermal or mechanical stress. Its compact dimensions (96×24×24mm) suit portable applications like digital voltmeters and recording systems. To preserve accuracy, avoid tilting or vibration during operation. The product is ideal for laboratories requiring reliable voltage benchmarks without frequent recalibration.1175
核心技術(shù)與性能特點(diǎn)
BC7-1采用飽和式結(jié)構(gòu)設(shè)計(jì)，電解液中保留過量硫酸鎘晶體以確保全溫區(qū)飽和狀態(tài)，從而降低溫度系數(shù)影響。電池內(nèi)阻約700Ω，隨使用時(shí)間可能輕微增加。其正面無柵線遮擋的設(shè)計(jì)優(yōu)化了空間利用率，同時(shí)避免光能損失。產(chǎn)品通過嚴(yán)格工藝控制實(shí)現(xiàn)0.01級(jí)準(zhǔn)確度，適合高精度場景如自動(dòng)記錄儀器或恒壓源配套。注意事項(xiàng)包括避免倒置、劇烈震動(dòng)及高溫環(huán)境存儲(chǔ)。2615
Technical Advantages and Applications
The BC7-1 utilizes a back-contact design that eliminates front-side grid shading, maximizing photon utilization efficiency. With an initial internal resistance of ~700Ω and low temperature hysteresis, it ensures reliable performance across varied environments. The cell’s 0.01-grade accuracy supports demanding applications such as potentiometric measurements and stable power supply calibration. Its sealed construction prevents electrolyte leakage, while the anti-shock design enhances durability. Recommended for academic research, industrial testing, and precision electronics development where voltage reference consistency is critical.5217
市場定位與兼容性
作為上海雙旭電子有限公司的成熟產(chǎn)品，BC7-1以高性價(jià)比滿足科研與工業(yè)需求，可適配多種直流儀器。其便攜式設(shè)計(jì)便于現(xiàn)場檢測，同時(shí)與不飽和標(biāo)準(zhǔn)電池（如BC24）形成互補(bǔ)，覆蓋不同溫漂要求的場景。用戶可根據(jù)實(shí)際需求選擇配套電池組（如BC11高精度系列）以擴(kuò)展應(yīng)用范圍。468
Market Positioning and Adaptability
Manufactured by specialized electronic suppliers, the BC7-1 balances cost and performance for global markets. It complements unsaturated cells (e.g., BC24) in applications requiring minimal temperature coefficient variations. The product line offers flexibility through compatible battery sets (e.g., BC11 series) for multi-channel systems. Its universal interface design simplifies integration with international equipment standards, making it a versatile choice for cross-border collaborative projects.4815
