FMQJ26直流双臂电桥
FMQJ26直流双臂电桥产品中文介绍
FMQJ26直流双臂电桥是一款采用惠斯登电桥电路设计的便携式精密测量仪器，主要用于中等阻值电阻（1Ω～9.999MΩ）的准确测量。其电路设计优化了传统电桥的性能，适合实验室、车间及户外环境使用。产品分为市电型和电池型两种供电模式，其中型号前缀“FM”代表市电型，可直接接入220V交流电源，适合固定场所；无前缀则为电池型，便于现场或无电源环境下操作。仪器内置高灵敏度电子检流计，无需外接附件即可快速完成电阻测量，测量步进精度可达5μΩ，满足金属导体电阻率、电机绕组电阻等低阻值场景的检测需求。机身采用紧凑设计（260×215×140mm），重量轻便，兼顾耐用性与操作便捷性。通过四端连接法可有效减少接线电阻和接触电阻的影响，提升小电阻测量的准确性。121317
FMQJ26 DC Double Bridge Product Introduction in English
The FMQJ26 DC double bridge is a portable precision instrument based on the Wheatstone bridge circuit, designed for accurate measurement of medium-range resistance (1Ω to 9.999MΩ). It features two power modes: AC-powered (marked with "FM" prefix) for stable lab use and battery-powered for field applications. The built-in high-sensitivity electronic galvanometer eliminates the need for external accessories, enabling rapid resistance measurement with a resolution of 5μΩ. Its compact design (260×215×140mm) ensures portability, while the four-terminal connection method minimizes the impact of lead resistance and contact resistance, enhancing accuracy in low-resistance measurements such as metal resistivity or motor winding tests. The instrument is suitable for diverse environments, including industrial sites and research facilities, offering reliable performance without complex setup.11829
产品特点与适用场景
FMQJ26直流双臂电桥在功能设计上注重实用性与适应性。其宽量程覆盖中阻到低阻测量需求，尤其适合电机、变压器绕组电阻、开关接触电阻等工业检测场景。市电型版本采用环保设计，无需频繁更换电池；电池型版本则通过优化电路降低功耗，延长户外使用时长。操作界面直观，配备步进盘和滑线盘双调节系统，用户可根据被测电阻预估值快速选择倍率（如×0.01、×1等），结合灵敏度可调的检流计实现精准平衡。仪器适用于材料研究、设备维护及教育实验等领域，帮助用户高效获取可靠数据。2722
Key Features and Applications
The FMQJ26 excels in versatility with its wide measurement range, catering to both industrial and educational needs. The AC-powered version provides continuous operation, while the battery-powered model ensures mobility. Its dual adjustment system (step dial and slide wire) simplifies operation, allowing users to select appropriate multipliers (e.g., ×0.01, ×1) based on estimated resistance values. The adjustable galvanometer sensitivity further enhances measurement precision. Typical applications include quality control of electrical components, material conductivity analysis, and academic experiments, offering a balance between performance and ease of use.71721
