FMT31普通型十進(jìn)電感箱
產(chǎn)品概述
FMT31普通型十進(jìn)電感箱是一款專為交流電路設(shè)計的教學(xué)與實驗用可調(diào)電感設(shè)備，適用于高校實驗室、科研單位及電子工程領(lǐng)域。該產(chǎn)品通過多盤步進(jìn)式結(jié)構(gòu)實現(xiàn)電感值的精確調(diào)節(jié)，可作為交流電橋、濾波電路、諧振網(wǎng)絡(luò)等場景中的可變標(biāo)準(zhǔn)感性元件。其設(shè)計注重實用性與穩(wěn)定性，采用耐高溫絕緣材料骨架，確保電感值在長時間工作中保持穩(wěn)定。36
功能特點
FMT31由三組步進(jìn)盤組成，分別提供0.1mH、1mH和10mH的最小步進(jìn)值，總電感調(diào)節(jié)范圍為0~111mH，滿足不同精度需求。每個步進(jìn)盤均設(shè)有獨立接線柱，支持串聯(lián)、并聯(lián)或單獨使用，靈活適配多種實驗配置。產(chǎn)品采用紅黑雙色接線柱標(biāo)識同名端，簡化連接操作。工作頻率兼容1kHz±20Hz正弦波，在環(huán)境溫度20±5℃、濕度80%條件下性能穩(wěn)定。外殼設(shè)計避免鐵磁材料干擾，確保測量準(zhǔn)確性。1917
技術(shù)參數(shù)
電感調(diào)節(jié)范圍：(0~10)×(0.1+1+10)mH，最大電感值111mH；步進(jìn)精度0.5%，額定電流分級為1.5A/1.0A/0.6A（對應(yīng)不同量程）。物理尺寸450×140×140mm，重量約3kg，采用工程塑料與金屬復(fù)合結(jié)構(gòu)，兼顧耐用性與便攜性。產(chǎn)品適用于阻抗匹配、功率因數(shù)校正等實驗場景，尤其適合高頻電路的教學(xué)演示。1218
應(yīng)用場景
廣泛應(yīng)用于電工電子類課程實驗，如RLC諧振特性分析、交流參數(shù)測定、二階電路響應(yīng)研究等。其模塊化設(shè)計便于學(xué)生理解電感疊加原理，多檔位調(diào)節(jié)功能可直觀展示電感值對電路特性的影響。在工業(yè)領(lǐng)域，可用于小型設(shè)備濾波電路調(diào)試或傳感器信號調(diào)理電路的阻抗匹配。313
Product Overview
The FMT31 Decade Inductance Box (Standard Type) is an adjustable inductance device designed for AC circuit experiments and educational purposes, widely used in university laboratories and electronic engineering applications. It features a multi-dial stepping mechanism to precisely adjust inductance values, serving as a variable inductive component in scenarios like AC bridges, filter circuits, and resonant networks. The product emphasizes practicality and stability, employing high-temperature-resistant insulating materials to maintain consistent performance.69
Key Features
With three decade dials providing minimum steps of 0.1mH, 1mH, and 10mH, the FMT31 covers a total adjustable range of 0~111mH. Each dial has independent terminals labeled with red/black markers for polarity identification, supporting series, parallel, or individual configurations. Compatible with 1kHz±20Hz sinusoidal waveforms, it operates stably under ambient temperatures of 20±5℃ and 80% humidity. The non-ferromagnetic enclosure minimizes external interference.117
Specifications
Inductance range: (0~10)×(0.1+1+10)mH (max 111mH); stepping accuracy 0.5%, rated current 1.5A/1.0A/0.6A (by range). Dimensions 450×140×140mm, weight ~3kg. The hybrid plastic-metal construction ensures durability. Ideal for demonstrating impedance transformation, harmonic filtering, and circuit tuning in both educational and prototyping environments.1218
Applications
Suited for electrical engineering curricula, including RLC resonance experiments, AC parameter measurement, and dynamic circuit analysis. The modular design aids in teaching inductance superposition principles. Industrial applications include signal conditioning in sensor interfaces and EMI filter debugging for compact electronic devices.313
