FMGd标准互感器/FMGd
FMGd标准互感器的产品介绍
FMGd标准互感器是一款专为直流和低频电磁测量设计的双线并绕空心线圈设备，适用于实验室、科研机构及高校教学场景。该产品采用优质陶瓷或塑料骨架（客户可自由选择材质），具有结构稳定、精度可靠的特点，可配合冲击电流计等设备使用，实现精确的电流变换与信号传递。其设计注重实用性，两组电感（L1和L2）通过红黑双色接线柱区分同名端，便于用户快速识别与连接。工作环境建议在20±2℃、相对湿度40%-80%的条件下运行，且需远离铁磁性物质以确保测量准确性。产品支持定制化需求，满足不同实验场景的特殊要求。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
技术特性与优势
FMGd互感器采用无铁芯设计，有效避免了磁滞效应，在0.001-0.1H量程内保持线性响应。绝缘性能优异，绕组间绝缘电阻达100MΩ以上，可承受500V/50Hz耐压测试。紧凑的尺寸（塑料骨架款约14×14×10cm）和轻量化设计（1.7kg）便于移动和安装。产品支持连续工作不超过2小时的安全操作模式，并采用全封闭结构防止环境污染物影响线圈性能。独特的工艺确保了两组线圈的对称性和温度稳定性，适用于需要长期重复实验的场合。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
