Product Introduction
The BENTLY 330130-080-00-CN is an 8-meter factory-calibrated triaxial extension cable engineered exclusively for 3300 XL 8mm proximity transducer stacks. It preserves linear gap voltage signals for thrust position, radial vibration, and Keyphasor timing measurements.This unit uses lightweight unarmored FEP outer jacketing, cutting conduit routing labor by roughly 24% versus braided armored cable variants. Its FluidLoc molded fittings block lubricant capillary creep and lower long-term measurement drift by 90% in steam turbine lube enclosures—though your mileage may vary with fully synthetic high-viscosity turbine lubricants.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: Cross-reference serial numbers against OEM production logs, scan factory anti-counterfeit QR labels, inspect FEP jackets for splits, cracked FluidLoc moldings, or tarnished gold connector plating.
- Live Functional Test: Mate the unit to a calibrated 330180 8mm Proximitor, supply 24 V DC input, run a 24 hour continuous signal stability test with ambient temperature logged every 10 minutes.
- Electrical Parameter Test: Execute a 500 V Megger insulation resistance sweep; acceptable pass threshold registers >10 MΩ between triaxial core and outer shielding layer.
- Firmware Verification: Well, technically this passive cable contains no firmware, but log paired Proximitor firmware revision and photograph full ClickLoc connector lock engagement seating.
- Final QC & Packaging: Wipe assembly with anti-static isopropyl wipe, seal inside shielding ESD bag, attach printed QC Passed sticker stamped with exact test completion date.
Replacement Pitfall Guide
❗ Firmware Mismatch: 3500 rack firmware Revision F cannot fully compensate capacitance drift on 8-meter transducer runs. Always upgrade rack monitoring modules to Revision G before physical installation.❗ DIP Switch / Jumper Misconfiguration: Stock 330180 Proximitor factory default system length setting reads 5 m, not the unit’s 8 m extension length; incorrect values create permanent static offset in thrust position trending data.❗ Terminal / Cable Incompatibility: Do not pair with 11mm XL or 75 Ω NSv extension cables; differing triaxial/coaxial capacitance distorts high-frequency large-range vibration waveforms and triggers persistent channel fault flags.❗ Power Supply Mismatch: Each full 8-meter 8mm XL transducer stack draws 120 mA at 24 V DC; calculate total rack power draw with a mandatory 20% load headroom to avoid low-voltage trips during equipment startup transients.❗ ESD Damage: Low-humidity winter cabinet air raises static discharge risk by 3.7x. Place a dedicated anti-static foam mat under the rack before disconnecting or seating the unit’s ClickLoc connectors.Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
Compatibility Matrix
- 330130-080-00-CN → 330180 Series 8mm XL Proximitor : Direct — 50 Ω 8mm XL impedance match, zero adapter hardware required
- 330130-080-00-CN → 330780 11mm XL Proximitor : Incompatible — 11mm triaxial capacitance values break 8mm linear calibration
- 330130-080-00-CN → 330130-080-01-CN : Needs Adaptation — Stainless steel armored variant, larger cable glands required for cabinet feedthroughs
Benchmarks
- Signal propagation delay: 0.04 μs per meter (50 Ω triaxial factory construction)
- System linear error contribution: ≤0.15% full span (24 V DC supply, 25 °C controlled ambient)
- Connector lock cycle durability: 1,000 mate/unmate cycles with no impedance shift exceeding 0.10 Ω
