FM-4R4四端夾具（雙臂電橋測低電阻專用)
FM-4R4四端夾具產品介紹
FM-4R4四端夾具是專為雙臂電橋測量低電阻設計的精密測試工具，適用于金屬導體、線纜、板材等材料的電阻率測量。該夾具采用龍門閘式結構，配備標尺和導桿，支持0.1m～1.1m長度的試樣，直徑范圍覆蓋0～φ40mm。其P2C2滑動設計允許靈活定位和拉緊，確保測量過程中接觸電阻最小化，從而提高數據準確性。夾具的四端連接方式有效消除了引線電阻和接觸電阻的干擾，適用于電機繞組、變壓器線圈、觸點接觸電阻等低阻值場景。產品結構穩(wěn)定，操作簡便，可直接與QJ44、QJ84等雙臂電橋配套使用，滿足工業(yè)實踐和實驗室的高精度需求。158
FM-4R4 Four-Terminal Fixture Product Description
The FM-4R4 four-terminal fixture is a precision testing device designed for low-resistance measurements using double-arm bridges, suitable for materials such as metal conductors, wires, and plates. It features a gantry-style structure with a built-in scale and guide rail, accommodating samples with lengths of 0.1m～1.1m and diameters up to φ40mm. The sliding P2C2 mechanism enables adjustable positioning and clamping, minimizing contact resistance during testing. The four-terminal connection method effectively eliminates interference from lead resistance and contact resistance, making it ideal for applications like motor windings, transformer coils, and contact resistance testing. With stable construction and user-friendly operation, the fixture is compatible with instruments such as QJ44 and QJ84 bridges, meeting high-precision requirements in both industrial and laboratory settings.3611
產品技術特點
FM-4R4采用刃口接觸設計，確保電位端（P1P2）與被測樣品形成可靠的線接觸，而電流端（C1C2）則通過無刃口結構增大接觸面積，保障電流穩(wěn)定性。夾具配備有機玻璃標尺和可滑動塑料模塊，便于精確讀取有效測量長度（lP1P2），并支持分段測量或逐差法數據處理。絕緣底座和獨立接線柱設計避免了外部干擾，適用于10⁻⁶Ω～100Ω范圍的電阻測量，如導電材料電阻率、焊接點電阻等場景。4816
Technical Features
The FM-4R4 employs blade-edge contacts at the potential terminals (P1P2) for reliable linear connection, while the current terminals (C1C2) utilize flat surfaces to enhance current stability. The acrylic scale and sliding plastic module allow accurate reading of the effective measurement length (lP1P2), supporting segmented testing or differential data analysis. Its insulated base and isolated terminals prevent external interference, suitable for resistance measurements ranging from 10⁻⁶Ω to 100Ω, including applications like material resistivity analysis and joint resistance testing. The fixture is widely used in electrical engineering and material science due to its repeatability and ease of integration with standard measurement instruments.5712
