Description
Bently 330130‑040‑01‑00
Technical Specifications: Cable Length: 4.0 m Nominal Impedance: 75 Ω Operating Temperature Range: ‑51 °C ~ +177 °C Minimum Static Bend Radius: 25.4 mm Connector Type: Click‑Loc gold‑plated self‑locking coaxial connector Maximum Tensile Load: 330 N Net Weight: 560 g Compatible System: 3300 XL 8 mm proximity transducer system
Functional Features: Interlocked AISI 302 stainless‑steel armor resists cutting, impact and mechanical crushing damage. Click‑Loc self‑locking connector prevents loosening under continuous machine vibration; installation and removal require no special tools. Full‑coverage coaxial shielding suppresses industrial EMI and RFI interference. Integrated CableLoc strain‑relief structures at both cable ends absorb pulling force and prevent inner conductor fracture. Factory‑matched electrical calibration eliminates on‑site recalibration after complete system assembly. FEP insulation jacket maintains stable signal performance under oil mist, dust and heavy‑pollution environment.
Application Scenarios: Shaft vibration, axial displacement and Keyphasor phase reference signal transmission for steam turbines, centrifugal compressors, gearboxes, process pumps and generators. Deployed in thermal‑power, petrochemical and metallurgical sites where wiring routes face mechanical scratch and collision risks.
Performance Parameters: Center Conductor DC Resistance: 0.88 Ω ±0.10 Ω Shield Conductor DC Resistance: 0.26 Ω ±0.06 Ω Connector Mating Cycle Life: More than 1000 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 Connector Body: Gold‑plated brass alloy Sealing Gasket: Oil‑resistant high‑temperature fluororubber
Structural Features: 75‑Ω coaxial inner cable assembly covered by interlocked corrugated stainless‑steel armor. Both cable ends adopt Click‑Loc self‑locking circular connectors equipped with O‑ring sealing gaskets. CableLoc strain‑relief transition sections are molded at two terminals. The whole cable is integrally manufactured without intermediate splice points.
Working Principle: Passive signal transmission assembly without signal conversion function. It faithfully transfers high‑frequency impedance‑variation signals generated by probe coil, maintains complete impedance matching of the whole proximity system, and preserves original amplitude and phase of gap‑voltage conversion output.
Installation Requirements: Respect minimum bend radius of 25.4 mm, never force sharp bending. Reserve sufficient cable slack to compensate for thermal expansion and machine vibration displacement. Route signal cable separately from high‑voltage power cables; never run together inside one conduit. Confirm full click‑loc engagement after connector mating. Implement single‑end grounding for cable shielding layer; double‑end grounding is strictly forbidden to avoid ground loop. Fasten cable with cable clamps at intervals; cable assembly shall not bear mechanical weight of equipment.
Usage Notes: Do not cut, truncate or splice original factory cable on‑site. Total length of probe built‑in cable plus extension cable must match Proximitor calibrated length. Operate only on connector housing during disconnection; never pull cable body to separate connectors. Periodically inspect sealing gasket integrity to prevent oil and moisture ingress into connector cavity.
