FMT50普通型十進(jìn)電感箱
產(chǎn)品概述
FMT50普通型十進(jìn)電感箱是一款專為高校實(shí)驗(yàn)、科研及工業(yè)應(yīng)用設(shè)計(jì)的精密電感調(diào)節(jié)裝置。該產(chǎn)品采用十進(jìn)式步進(jìn)調(diào)節(jié)結(jié)構(gòu)，可提供(0～10)×(0.01+0.1+1+10+100)mH的寬范圍電感值調(diào)節(jié)，滿足多樣化的電路實(shí)驗(yàn)需求。其核心功能是通過多盤組合實(shí)現(xiàn)電感值的精確控制，適用于交流電路中的濾波器設(shè)計(jì)、阻抗變換和諧振電路等場景。產(chǎn)品采用耐高溫、絕緣性能優(yōu)異的材料制成骨架，確保電感穩(wěn)定性，同時通過紅黑雙色接線柱標(biāo)識同名端，便于用戶快速連接與調(diào)試。1919
技術(shù)特點(diǎn)
FMT50由五只步進(jìn)盤組成，最大電感值為11111.0mH，最小步進(jìn)0.1mH，調(diào)節(jié)精度高。外型尺寸為450×250×140mm，采用非金屬底座設(shè)計(jì)以減少鐵磁性干擾。工作頻率推薦1kHz±20Hz正弦波環(huán)境，額定電流為1.5A（最小步進(jìn)盤）至0.015A（最大步進(jìn)盤），用戶需根據(jù)實(shí)際需求選擇工作電流以避免過載。產(chǎn)品支持多盤獨(dú)立使用或串聯(lián)組合，靈活性高，且每個步進(jìn)盤均經(jīng)過人工老化與自然老化處理，確保長期穩(wěn)定性。81123
應(yīng)用場景
FMT50廣泛應(yīng)用于電工學(xué)教學(xué)實(shí)驗(yàn)，如一階/二階電路響應(yīng)測試、功率因數(shù)提升實(shí)驗(yàn)等。在工業(yè)領(lǐng)域，可作為可變標(biāo)準(zhǔn)電感器用于交流電橋校準(zhǔn)或阻抗匹配。其模塊化設(shè)計(jì)允許用戶根據(jù)實(shí)驗(yàn)復(fù)雜度自由擴(kuò)展，例如在諧振電路中實(shí)現(xiàn)精確頻率調(diào)諧。使用時需注意避免金屬接觸底座，并盡量減少引線包圍面積以降低誤差。產(chǎn)品適用于20±5℃、相對濕度80%以下的環(huán)境，存放時需保持旋鈕朝上以保護(hù)內(nèi)部結(jié)構(gòu)。21416
英文介紹 (Product Overview)
The FMT50 Decade Inductance Box is a precision instrument designed for educational and industrial applications, featuring a decade-stepping mechanism with adjustable range of (0～10)×(0.01+0.1+1+10+100)mH. Its multi-dial design allows independent or combined use of five inductance steps, achieving a maximum inductance of 11111.0mH and minimum increment of 0.1mH. The non-metallic base minimizes magnetic interference, while color-coded terminals (red/black) simplify circuit connections. Ideal for AC circuit experiments like filtering and impedance transformation, it operates optimally at 1kHz±20Hz sinusoidal waveforms with current ratings from 1.5A to 0.015A per dial. The compact dimensions (450×250×140mm) and modular structure enhance portability and adaptability for diverse experimental setups.31220
Key Features
Constructed with high-temperature-resistant insulation materials, the FMT50 ensures stable inductance values under prolonged use. Each dial undergoes rigorous aging processes (both artificial and natural) to guarantee long-term reliability. The product supports flexible configurations—users may isolate single dials or cascade multiple units for extended ranges. Environmental recommendations include operation within 20±5℃ and humidity below 80%, with storage orientation (knob-up) to prevent mechanical deformation. Its applications span from university labs for teaching resonance phenomena to industrial settings requiring tunable reference inductors.91522
Usage Notes
When integrating the FMT50 into circuits, avoid placing it near ferromagnetic materials or metal surfaces to prevent measurement deviations. For multi-dial setups, limit maximum current based on the highest-range dial’s rating (e.g., 0.015A for 1000mH steps). The device’s open-frame design facilitates maintenance, though direct exposure to dust or moisture should be avoided. Educational users benefit from its compatibility with standard breadboards and transparent circuit visualization, while industrial adopters value its repeatability in calibration workflows.172124
