Bently 330130-045-01-CN 3300‑XL Armored Tri‑axial Extension Cable

Description

Hardware Specifications

• Part Type: 3300‑XL armored tri‑axial extension cable, dual‑ended gold‑plated ClickLoc miniature coaxial connectors
• Cable Length: 4.5 meters (14.8 ft)
• Impedance: 75 Ω nominal; FEP insulation material; typical capacitance 69.9 pF/m
• Mechanical Construction: Flexible AISI‑302 stainless‑steel interlocked armor over FEP outer jacket; CableLoc reinforced connector‑to‑cable junction; armor provides high resistance against crush, abrasion and tensile stress
• Environmental Ratings: Operating temperature −35 °C ~ +105 °C; storage −40 °C ~ +185 °C; relative humidity 5‑95 % non‑condensing
• Electrical Compatibility: Matches 3300‑XL 5 mm / 8 mm proximity probes and 3300‑XL proximitor sensors. Total transducer‑system length (probe integral cable + extension cable) must strictly match calibrated proximitor system length. Suffix‑CN denotes Chinese‑market documentation and packaging, no international hazardous‑location approvals。

Core Functions

1. Transmits high‑frequency eddy‑current sensor signal between proximity probe and proximitor sensor, maintaining signal integrity for gap‑voltage conversion, radial‑vibration and thrust‑position measurement. Stainless‑steel armor protects inner tri‑axial core against mechanical abrasion, crushing and sharp‑object damage in high‑wear machine compartments.
2. Deployed on steam‑turbines, gas‑turbines, centrifugal compressors and other critical rotating‑machinery as part of 3300‑XL transducer set, paired with 3500‑series / 1900‑series monitoring systems for machinery protection and condition‑diagnosis. Preferred for locations where non‑armored cable would be subject to mechanical abuse. CN variant is supplied with China‑regional documentation and packaging.
3. Must maintain correct total system cable length; mismatched total length will shift sensitivity, degrade linear performance and produce erroneous gap‑voltage readings.
4. The ClickLoc “click‑and‑turn” connector design provides repeatable, low‑contact‑resistance mating between transducer components.
5. Widely used in power‑generation, petrochemical and oil‑gas industrial sites. Distinguished ordering code:‑045‑ defines 4.5 m length,‑01‑ defines stainless‑steel armored construction,‑CN‑ defines China‑regional variant. Replacement requires re‑verification of total transducer‑system length and gap‑voltage calibration。

Installation Requirements

1. Routing requirement: Route cable separate from high‑voltage power and large‑current motor cables to suppress electromagnetic interference. Avoid sharp bends, crushing and tensile pulling. Minimum cable bend radius 25.4 mm at all points along cable run. Armor does not permit sharp small‑radius bending.
2. Connector handling: Mate ClickLoc connectors finger‑tight plus maximum 1/8‑turn; over‑torque will damage gold‑plated contact pins. Do not disassemble connector assemblies. Avoid twisting cable armor during installation.
3. Grounding rule: Single‑point shield grounding implemented at proximitor‑sensor end only to eliminate ground‑loop noise. Armor shall not be used as signal ground path.
4. Environmental control: Prevent continuous direct immersion and heavy‑fluid splashing at cable‑to‑connector junction. Armor provides mechanical protection but does not make cable submersible. Outer‑jacket and armor deformation will cause inner‑core damage and signal faults.
5. Pre‑installation visual inspection: Inspect stainless‑steel armor for kinks, crushed sections or broken armor strands; inspect cable jacket for cuts; inspect both‑end ClickLoc connector pins for bending, corrosion or contamination before commissioning. After full transducer assembly, measure static gap voltage to verify valid linear‑range operation.
6. Part‑number cross‑version distinction: 330130‑045‑01‑CN is stainless‑steel armored 4.5 m extension cable for Chinese market without hazardous‑area certifications. Non‑armored, FluidLoc, agency‑approved variants cannot be interchanged without re‑calculating total system length. Different‑length extension cables are not direct drop‑in substitutes; replacement demands full system‑length validation and gap‑voltage calibration。

Common Failure Modes

‑ Armor kink/crushing leading to inner tri‑axial conductor micro‑fracture: intermittent gap‑voltage drift, noisy vibration readings, sporadic signal drop‑out. ‑ Improper bend radius or tensile pull stress: internal conductor damage, gradual signal degradation, hidden intermittent faults. ‑ ClickLoc connector pin contamination, corrosion or over‑torque damage: unstable signal connection, high‑frequency noise superimposed on vibration waveform. ‑ Multi‑point shield grounding: ground‑loop induced noise, unstable gap‑voltage output. ‑ Mismatched total transducer‑system length: incorrect sensitivity, offset gap‑voltage, invalid measurement data.
