FM-4R4四端夾具（雙臂電橋測(cè)低電阻專(zhuān)用)
FM-4R4四端夾具產(chǎn)品介紹
FM-4R4四端夾具是專(zhuān)為雙臂電橋測(cè)量低電阻設(shè)計(jì)的精密測(cè)試工具，適用于金屬導(dǎo)體、線纜、板材等材料的電阻率測(cè)量。該夾具采用龍門(mén)閘式結(jié)構(gòu)，配備標(biāo)尺和導(dǎo)桿，支持0.1m～1.1m長(zhǎng)度的試樣，直徑范圍覆蓋0～φ40mm。其P2C2滑動(dòng)設(shè)計(jì)允許靈活定位和拉緊，確保測(cè)量過(guò)程中接觸電阻最小化，從而提高數(shù)據(jù)準(zhǔn)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(jī)繞組、變壓器線圈、觸點(diǎn)接觸電阻等低阻值場(chǎng)景。產(chǎn)品結(jié)構(gòu)穩(wěn)定，操作簡(jiǎn)便，可直接與QJ44、QJ84等雙臂電橋配套使用，滿足工業(yè)實(shí)踐和實(shí)驗(yàn)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(chǎn)品技術(shù)特點(diǎn)
FM-4R4采用刃口接觸設(shè)計(jì)，確保電位端（P1P2）與被測(cè)樣品形成可靠的線接觸，而電流端（C1C2）則通過(guò)無(wú)刃口結(jié)構(gòu)增大接觸面積，保障電流穩(wěn)定性。夾具配備有機(jī)玻璃標(biāo)尺和可滑動(dòng)塑料模塊，便于精確讀取有效測(cè)量長(zhǎng)度（lP1P2），并支持分段測(cè)量或逐差法數(shù)據(jù)處理。絕緣底座和獨(dú)立接線柱設(shè)計(jì)避免了外部干擾，適用于10⁻⁶Ω～100Ω范圍的電阻測(cè)量，如導(dǎo)電材料電阻率、焊接點(diǎn)電阻等場(chǎng)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
