Product Introduction

Serving as the critical signal pathway in the Bently Nevada 3300 XL sensor system, this 330130-045-02-05 extension cable ensures that microvolt-level eddy current signals travel from the proximity probe to the Proximitor transmitter without degradation. Its triaxial construction and FEP insulation provide exceptional immunity to electromagnetic interference (EMI) and radio frequency interference (RFI) in harsh industrial environments.

The “-02” in the part number designates the Micro ClickLoc™ connector type on both ends, providing a secure, vibration-resistant connection that can be tightened by hand. The CableLoc™ patent design prevents accidental cable pull-out, while the optional FluidLoc™ variant (if applicable to your specific sub-revision) prevents oil or coolant from wicking through the cable internals into the machine enclosure.

 

QA & Testing SOP

Extension cables are passive but their electrical integrity is paramount. We verify signal transmission quality and mechanical durability.

1. Anti-Counterfeit & Visual Audit: We inspect the Bently Nevada cable jacket printing, verify the 330130-045-02-05 part number, and check both ClickLoc connectors for bent center pins or damaged locking threads.
2. Core Continuity & Shield Test: We perform a low-resistance sweep on the center conductor and verify the braided shield has zero breaks, ensuring EMI noise won’t corrupt the vibration signal.
3. Impedance Verification: We verify the cable’s characteristic impedance matches the 3300 XL system specification to prevent signal reflections that cause measurement errors.
4. Connector Mating Test: We mate both ends with known-good probes and Proximitor transmitters to verify secure ClickLoc engagement and consistent electrical contact.
5. ESD Safe Packaging: While passive, the cable connects to sensitive analog front-ends. We pack in anti-static shielding to prevent static discharge damage during handling.

Installation Pitfalls & Guide

❗ System Length Matching: This is the most critical rule. The electrical length of this cable (4.5m) PLUS the probe’s integrated cable length MUST exactly equal the Proximitor transmitter’s configured system length. For example, a 1.0m probe + this 4.5m cable = 5.5m total, requiring a 5.5m (or nearest standard) Proximitor. Mismatched lengths cause severe calibration errors.

❗ Minimum Bend Radius: Never bend this cable tighter than 25.4 mm (1 inch). Sharp bends damage the internal triaxial structure, causing intermittent signals or complete failure. Route cables with gentle curves and use proper strain relief.

❗ Single-Point Shield Grounding: The cable shield must be grounded at the Proximitor transmitter end ONLY. Grounding at both the probe bracket and the transmitter creates a ground loop that injects 50/60Hz hum directly into your vibration readings.

❗ Connector Torque: ClickLoc connectors are hand-tightened. Do not use wrenches or pliers. Over-torquing damages the connector threads and degrades the RF seal. Finger-tight plus a quarter turn is sufficient.

Replacement SOP:

1. Pre-Install: Record the existing probe gap voltage and verify the total system length (probe + cable); place the machine in bypass/maintenance mode.
2. Removal: Disconnect the ClickLoc connector from the Proximitor; unthread the probe-side connector; carefully route the old cable out.
3. Install: Route the new 330130-045-02-05 cable away from high-EMI sources (VFDs, motor leads); connect probe side first, then Proximitor side; verify ClickLoc locks engage.
4. Power-On Test: Apply power to the Proximitor; verify the gap voltage reads within spec (-10 VDC ± 0.2V typical); confirm DCS vibration readings are stable before removing bypass.

 

Technical FAQ

What does the “-02-05” in the part number mean?
The “-02” designates the connector type: Micro Coaxial ClickLoc™ connectors on both ends. The “-05” typically indicates multi-agency approval (ATEX, IECEx, CSA, etc.) for hazardous area installations. This cable is suitable for use in classified environments.

Can I use this cable with a 5mm or 11mm probe?
No. The 330130-045-02-05 is specifically designed for the 3300 XL 8mm sensor system. While the ClickLoc connector may physically mate with some other probe sizes, the electrical characteristics (impedance, capacitance) are calibrated for 8mm probes. Using mismatched cables causes calibration errors.

Is this cable compatible with 3500/42M monitors?
Yes, indirectly. This cable connects the 3300 XL 8mm probe to a 3300 XL Proximitor transmitter (e.g., 330180-50-xx). The Proximitor then outputs a conditioned signal to the 3500/42M monitor. The extension cable itself does not connect directly to the 3500 rack.

What is the difference between standard and FluidLoc cable?
FluidLoc cables have an internal barrier that prevents oil, coolant, or other liquids from wicking through the cable internals from the probe end to the Proximitor end. Standard cables do not have this feature. If your probe is installed in an oil-lubricated bearing housing, FluidLoc is strongly recommended.

Why is this sold as new surplus?
This unit was pulled from sealed OEM overstock or an unfulfilled project before installation. We test it electrically to verify signal integrity and connector quality, but we aren’t replacing internal components. You’re getting unused factory cable with original manufacturing tolerances at a fraction of the active OEM list price.
