Product Introduction
This armored triaxial extension cable is designed for harsh industrial cabinet environments where cables face sharp metal edges, repeated friction, heavy compression or tensile pull loads that would damage standard non-armored cables. The factory-calibrated matched triaxial design preserves linear gap voltage response over long wiring runs, avoiding vibration measurement drift and orbit distortion under turbine thermal load transients.
FluidLoc molded end joints block machine lubrication oil ingress, a common failure mode for generic aftermarket replacement cables. This unit cannot operate standalone; a complete measurement system requires probe + extension cable + Proximitor conditioner paired with 3500 series monitor racks.
Key difference vs non-armored 330130-040-00-00: Stainless steel braided armor adds robust mechanical protection, but thicker outer diameter requires larger cable gland fittings during site installation. It is electrically identical and fully interchangeable with non-armored 8mm extension cables if mechanical routing hazards exist.Strict compatibility limit: Only works with 8mm 3300 XL probe systems; incompatible with 11mm 330730 series cables due to different capacitance and impedance matching parameters.
Firmware/Software Versions & Upgrade Notes
This cable is a passive analog transmission assembly with no onboard firmware. System compatibility rules apply to paired Proximitor and 3500 rack monitors:Minimum compatible 3500 monitor firmware: Revision G; minimum Rack Configuration Software v2.00. All M-series monitor modules must run unified matching firmware revisions to correctly interpret 3300 XL linear gap voltage characteristic curves.No cable-specific software configuration is required after physical installation; only the total combined length (probe length + 4m extension cable) must be entered into rack configuration software to lock transducer sensitivity calibration. Always verify total system length before commissioning to eliminate static measurement offset errors.
Frequently Asked Questions (FAQ)
- Is hot-disconnecting the cable safe while the 3500 rack remains energized?Proximitor and TSI rack monitors stay powered during connector removal. Unplugging this cable triggers persistent channel fault flags and temporary loss of vibration/thrust position data, but no permanent damage occurs to monitor analog input circuits. Fully re-seat both ClickLoc connectors until the locking tab clicks to clear fault alarms.
- Is this part obsolescent, and are direct drop-in hardware upgrades available?This armored cable remains an active OEM catalog spare with no formal end-of-life date. The certified upgrade variant is 330130-040-01-05, which adds ATEX, IECEx, CSA hazardous location approvals; it shares identical mechanical/electrical performance but requires additional site hazardous area documentation, so it is not zero-modification plug-and-play for non-hazardous cabinets.
- Will transducer linearity or gap calibration data erase if the rack loses full power?All system sensitivity and total length calibration parameters store in non-volatile flash memory on the paired 3500 monitor module, not the cable assembly itself. Full rack power loss does not erase transducer configuration data; swapping this unit requires only physical reconnection with no software rework if total system length stays unchanged.
- What warranty terms separate New Surplus inventory from refurbished alternatives?New Surplus cable assemblies carry a 12-month functional warranty covering triaxial impedance consistency, stainless armor structural integrity, gold connector plating integrity, FluidLoc molded seal performance. Refurbished cables typically offer only 3–6 month limited coverage and carry hidden risks of cracked FEP insulation, broken braided armor strands, worn connector locking tabs, and compromised liquid sealing that cause drifting vibration readings during turbine thermal cycles.
- Why does New Surplus pricing sit higher than generic used/refurbished marketplace listings?All New Surplus cable assemblies complete mandatory standardized QC validation: serial traceability cross-check against OEM production logs, full length impedance and capacitance bench testing, tensile pull-load testing to validate FluidLoc joint adhesion, armor abrasion durability testing, 1000-cycle connector lock durability testing, and sealed anti-static factory packaging. Refurbished lots skip this multi-step electrical and mechanical validation workflow, introducing unplanned downtime risk for safety-critical turbine vibration and thrust position protection loops.
- Can this armored cable mate with legacy 11mm 3300 XL proximity probes (33070x series)?No, the ClickLoc internal pinout and 50Ω triaxial capacitance profile are exclusive to 8mm 33010x probe systems. 11mm probe hardware uses dedicated 330730 series extension cables with different electrical matching parameters. Verify against the OEM 3300 XL datasheet before cross-mixing transducer hardware to avoid permanent Proximitor input circuit damage.
- Does the cable locally store vibration waveforms or long-term rotor position trending logs?No, the assembly is a fully passive analog signal transmission component with zero memory or signal processing hardware. All vibration amplitude, axial thrust displacement, and Keyphasor rotational speed trending records are captured and retained exclusively by the Slot1 3500/20 TDI master communication gateway module. This cable only conducts raw high-frequency eddy-current gap signals without modifying or storing measurement data.
