Engineered for the most demanding industrial environments, this extension cable bridges the gap between the proximity probe and the Proximitor Sensor, ensuring the seamless transmission of high-frequency eddy current signals. In large-scale rotating machinery monitoring, such as steam turbines and heavy-duty compressors, signal integrity is non-negotiable. This cable utilizes advanced shielding technology to eliminate electromagnetic interference (EMI), providing the precision required for accurate vibration and axial position measurements. Its robust design facilitates integration into Turbine Supervisory Instrumentation (TSI) racks, forming a vital link in machinery protection and emergency shutdown (ESD) protocols.\u003c\/p\u003e\n\u003ch2\u003eModel Configuration Breakdown\u003c\/h2\u003e\n\u003ch3\u003e129957 - 3300 XL 50mm Extension Cable\u003c\/h3\u003e\n\u003cp\u003eThe 129957 series is specifically matched for the 50mm transducer system, which handles larger displacement ranges than standard 8mm systems.\u003c\/p\u003e\n\u003ch3\u003e-085 - Total Length Option\u003c\/h3\u003e\n\u003cp\u003eThis suffix indicates a total length of 8.5 meters (approximately 27.9 feet).

Always utilize the ClickLoc connector system by ensuring a positive \"click\" is felt during mating; this prevents signal intermittent issues caused by machine resonance. When routing the cable through conduit, avoid tight 90-degree bends that exceed the minimum 25.4 mm radius, as this can degrade the coaxial shield's performance. For explosive atmospheres, ensure the cable is secured within grounded metal conduits or approved cable trays to maintain the integrity of the intrinsic safety barrier.\u003c\/p\u003e\n\u003ch2\u003eIndustrial Performance Advantages\u003c\/h2\u003e\n\u003cp\u003eThe 3300 XL 50mm system is the gold standard for long-range displacement sensing. Unlike inferior third-party alternatives, this genuine Bently Nevada cable maintains a constant impedance, which prevents \"signal drift\" in high-temperature turbine housings. It integrates natively with Bently Nevada 3500\/05 racks and Honeywell Experion PKS platforms, allowing for real-time diagnostics of the transducer gap voltage. Its specialized insulation resists corrosive lubricants and high-pressure steam environments, ensuring that your vibration data remains accurate over years of continuous operation.\u003c\/p\u003e\n\u003ch2\u003eFulfillment \u0026amp; Packaging\u003c\/h2\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eOne Brand New Bently Nevada 129957-085-310-05 Extension Cable.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eOriginal factory test certificate and calibration sheet.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSilicon connector protectors (pre-installed).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSealed anti-static moisture-barrier bag.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping \u0026amp; Logistics\u003c\/h2\u003e\n\u003cp\u003eExpect delivery within 2-7 business days following payment confirmation.

Proximity systems are tuned to specific electrical lengths. Altering the physical length changes the capacitance, which will lead to massive calibration errors in the Proximitor Sensor.\u003c\/p\u003e\n\u003cp\u003eQ2: How do I identify a \"310\" connector versus a standard one?\u003c\/p\u003e\n\u003cp\u003eA2: The -310 option features the ClickLoc design. You will feel a physical detent and hear a click when the connection is fully seated, and it requires a specific pull-and-twist motion to disconnect.\u003c\/p\u003e\n\u003cp\u003eQ3: Is this cable compatible with the standard 3300 XL 8mm probe?\u003c\/p\u003e\n\u003cp\u003eA3: No. The 129957 series is specifically engineered for the 50mm system. Using it with an 8mm or 11mm probe will result in incorrect scale factors and non-linear output.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518907670701,"sku":"129957-085-310-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-129957-085-310-05-extension-cable-pkh3fygrqbn.jpg?v=1766981318","url":"https:\/\/www.maxwellplc.com\/products\/bently-nevada-129957-085-310-05-3300-xl-50mm-proximity-extension-cable","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
