Shield continuity and coaxial geometry maintain controlled return-path impedance, limiting signal distortion under high-density routing conditions in turbine and compressor instrumentation racks. This behavior directly influences stability of gap voltage interpretation and reduces phase distortion in multi-channel rotor dynamic measurements.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 84170-01 support hot-swap during active proximity monitoring?\u003cbr\u003eA: No. The cable is part of the analog signal path. Disconnection under energized probe conditions interrupts gap voltage continuity and invalidates measurement output at the Proximitor input stage.\u003c\/p\u003e\n\u003cp\u003eQ: What is the electrical impact of excessive cable length beyond system design limits?\u003cbr\u003eA: Increased cable length introduces attenuation and phase shift in the eddy-current signal path, affecting calibration scaling and reducing accuracy of displacement conversion.\u003c\/p\u003e\n\u003cp\u003eQ: Is the shielding layer required to be grounded at both ends?\u003cbr\u003eA: Standard Bently Nevada practice is single-point grounding of the shield at the monitoring system end to minimize ground loop currents in the signal return path.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the 84170-01 with continuous shield integrity from probe interface to Proximitor input terminal. Avoid sharp bend radius below manufacturer coaxial cable mechanical limits. Maintain separation from high-voltage AC conductors and switching relays to reduce inductive coupling. Ensure connector mating surfaces are clean and fully engaged to specified torque\/locking condition. Verify shield termination continuity and absence of open-circuit or intermittent grounding prior to system commissioning.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":44307099779160,"sku":"84170-01","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/84170-01-3.jpg?v=1782986524","url":"https:\/\/www.industriaxplc.com\/ar\/products\/84170-01-proximity-probe-extension-cable-assembly-bently-nevada","provider":"IndustriaX Limited","version":"1.0","type":"link"}
