FMGd標(biāo)準(zhǔn)互感器/FMGd
FMGd標(biāo)準(zhǔn)互感器的產(chǎn)品介紹
FMGd標(biāo)準(zhǔn)互感器是一款專為直流和低頻電磁測(cè)量設(shè)計(jì)的雙線并繞空心線圈設(shè)備，適用于實(shí)驗(yàn)室、科研機(jī)構(gòu)及高校教學(xué)場(chǎng)景。該產(chǎn)品采用優(yōu)質(zhì)陶瓷或塑料骨架（客戶可自由選擇材質(zhì)），具有結(jié)構(gòu)穩(wěn)定、精度可靠的特點(diǎn)，可配合沖擊電流計(jì)等設(shè)備使用，實(shí)現(xiàn)精確的電流變換與信號(hào)傳遞。其設(shè)計(jì)注重實(shí)用性，兩組電感（L1和L2）通過(guò)紅黑雙色接線柱區(qū)分同名端，便于用戶快速識(shí)別與連接。工作環(huán)境建議在20±2℃、相對(duì)濕度40%-80%的條件下運(yùn)行，且需遠(yuǎn)離鐵磁性物質(zhì)以確保測(cè)量準(zhǔn)確性。產(chǎn)品支持定制化需求，滿足不同實(shí)驗(yàn)場(chǎng)景的特殊要求。168
FMGd Standard Mutual Inductor Product Introduction
The FMGd standard mutual inductor is a dual-winding air-core coil device designed for DC and low-frequency electromagnetic measurements, widely used in laboratories, research institutions, and university teaching. Available with ceramic or plastic frames (customizable upon request), it ensures structural stability and reliable precision when paired with equipment like ballistic galvanometers. The device features two inductance groups (L1/L2) with color-coded terminals (red/black) for easy polarity identification. Optimal performance is achieved within 20±2℃ ambient temperature and 40%-80% humidity, while avoiding proximity to ferromagnetic materials. Its open-frame design allows flexible integration into diverse experimental setups, with optional modifications available for specialized applications. The product emphasizes user-friendly operation and long-term durability under proper storage conditions (5-40℃ dry environment).168
技術(shù)特性與優(yōu)勢(shì)
FMGd互感器采用無(wú)鐵芯設(shè)計(jì)，有效避免了磁滯效應(yīng)，在0.001-0.1H量程內(nèi)保持線性響應(yīng)。絕緣性能優(yōu)異，繞組間絕緣電阻達(dá)100MΩ以上，可承受500V/50Hz耐壓測(cè)試。緊湊的尺寸（塑料骨架款約14×14×10cm）和輕量化設(shè)計(jì)（1.7kg）便于移動(dòng)和安裝。產(chǎn)品支持連續(xù)工作不超過(guò)2小時(shí)的安全操作模式，并采用全封閉結(jié)構(gòu)防止環(huán)境污染物影響線圈性能。獨(dú)特的工藝確保了兩組線圈的對(duì)稱性和溫度穩(wěn)定性，適用于需要長(zhǎng)期重復(fù)實(shí)驗(yàn)的場(chǎng)合。168
Technical Features
With its non-ferrous core construction, the FMGd eliminates hysteresis distortion while maintaining linear response across 0.001-0.1H ranges. It boasts excellent insulation (＞100MΩ between windings) and withstands 500V/50Hz dielectric strength tests. The compact dimensions (plastic frame: 14×14×10cm) and lightweight (1.7kg) design enhance portability. Safety features include a 2-hour continuous operation limit and sealed structure to protect coils from contamination. Precision winding technology guarantees coil symmetry and thermal stability for repeatable experimental results. Custom specifications can be accommodated through manufacturer consultation.168
