Description
Bently 330130‑045‑01‑01
Technical Specifications: Cable Length: 4.5 m Nominal Impedance: 75 Ω Operating Temperature Range: ‑51 °C ~ +177 °C Minimum Static Bend Radius: 25.4 mm Connector Type: Reinforced mechanical‑lock Click‑Loc gold‑plated coaxial connector Maximum Tensile Load: 380 N Net Weight: 640 g Compatible System: 3300 XL 8 mm proximity transducer system
Functional Features: Interlocked stainless‑steel armor resists cutting, impact and squeeze damage. Reinforced mechanical‑lock connector improves anti‑loosening performance under severe high‑amplitude machine‑vibration. Full‑coaxial‑shielding suppresses EMI‑RFI industrial noise. Dual‑end heavy‑duty CableLoc strain‑relief structures resist higher tensile‑force. Factory‑calibrated electrical matching eliminates field recalibration. FEP insulation jacket withstands oil‑mist, dust and corrosive‑atmosphere.
Application Scenarios: Shaft‑vibration, axial‑displacement and Keyphasor‑reference signal transmission for heavy‑duty steam‑turbines, large centrifugal‑compressors, heavy‑load gear‑boxes. Deployed at petrochemical, thermal‑power and metallurgical field‑wiring points with heavy‑mechanical‑interference risk.
Performance Parameters: Center Conductor DC Resistance: 0.99 Ω ±0.12 Ω Shield Conductor DC Resistance: 0.30 Ω ±0.08 Ω Connector Mating Cycle Life: More than 1200 insert‑extract cycles Maximum Operating Relative Humidity: 93 % non‑condensing Nominal Capacitance: 69.9 pF/m
Material Composition: Inner Insulation Layer: Fluoroethylene‑Propylene (FEP) Signal Conductor: High‑purity silver‑plated copper Outer Armor Layer: AISI 302 interlocked stainless‑steel Reinforced Connector Body: Gold‑plated high‑strength brass‑alloy Sealing Gasket: High‑strength fluororubber
Structural Features: 75‑Ω coaxial inner‑cable wrapped by interlocked corrugated stainless‑steel armor. Both cable ends adopt reinforced mechanical‑lock Click‑Loc circular‑connectors with heavy‑duty O‑ring‑seals. Heavy‑duty CableLoc strain‑relief transition sections molded at two terminals. Whole‑cable integral‑manufacturing without intermediate‑splice‑points.
Working Principle: Passive signal‑transmission assembly with no signal‑conversion function. Faithfully transfers high‑frequency impedance‑variation signal from probe coil, maintains complete‑system impedance‑matching, keeps gap‑voltage‑conversion amplitude‑phase‑characteristics unchanged. Armor‑layer provides mechanical‑shielding for inner coaxial cable.
Installation Requirements: Respect minimum static‑bend‑radius 25.4 mm, avoid sharp‑bending. Reserve sufficient‑cable‑slack for thermal‑expansion and vibration‑displacement. Separate signal‑cable routing from high‑voltage‑power‑cables, forbid shared‑conduit. Confirm full mechanical‑lock engagement upon connector‑mating. Ground armor‑layer separately; shielding‑layer applies single‑end‑grounding, double‑end‑grounding forbidden. Fasten‑cable with metal‑clamps; cable assembly shall not bear equipment‑mechanical‑weight.
Usage Notes: Forbid field cutting, truncating or splicing original‑factory‑cable. Total‑length sum of probe‑integral‑cable plus extension‑cable must match Proximitor‑calibrated‑length. Operate only on reinforced‑connector‑housing for connection‑disconnection; never pull‑cable‑body. Regularly inspect heavy‑duty‑seal‑gasket integrity, prevent oil‑moisture‑corrosion on inner‑contact‑pins.
