Key Technical Specifications

Product Introduction

This triaxial extension cable forms the signal link between eddy-current proximity probes and rack-mounted Proximitor signal conditioners. The matched impedance triaxial construction eliminates high-frequency signal distortion that would degrade vibration and displacement measurement accuracy across long wiring runs.

FluidLoc sealed cable joints block machine lubrication oil ingress, a common failure point on unmodified third-party replacement leads. The unit cannot function independently; it requires a complete transducer stack of probe, extension cable, and Proximitor to deliver linear gap voltage outputs to 3500 series monitor modules. Armored variants exist for heavy mechanical abrasion environments but require separate site wiring validation.

Firmware/Software Versions & Upgrade Notes

No onboard firmware exists on the unit, as it is a passive analog signal transmission cable. System compatibility is governed by Proximitor sensor and 3500 rack monitor firmware rules:Minimum compatible 3500 monitor firmware: Revision G; minimum Rack Configuration Software v2.00. All installed monitor modules must run matching M-series firmware builds to correctly interpret the 3300 XL transducer linear gap output characteristic.No cable-specific software configuration is required post-install; only total system length (probe + extension cable) must be entered into the rack software to calibrate transducer sensitivity. Always cross-verify combined probe and extension cable total length before commissioning to avoid measurement offset errors.

Frequently Asked Questions (FAQ)

1. Is hot-swapping the cable safe while the 3500 rack remains energized?The Proximitor and rack monitors remain powered during connector disconnection. Unplugging this unit mid-operation triggers channel fault flags on the TSI rack and forces temporary loss of vibration/displacement data, but it does not damage the monitor’s analog input circuits. Re-seat connectors fully until the ClickLoc locking mechanism engages to clear fault alarms.
2. Is this part obsolescent, and are direct drop-in hardware upgrades available?This cable remains an active OEM catalog spare with no formal end-of-life date. The direct mechanical upgrade variant is 330130-040-01-00, which adds stainless steel braided armor for abrasive cabinet routing; it shares identical connector pinout and electrical performance but is not a zero-modification swap due to thicker outer diameter requiring larger cable glands.
3. Will transducer linearity or gap calibration data erase if the rack loses full power?All system sensitivity and total length calibration values store in non-volatile flash memory on the paired 3500 monitor module, not the cable itself. Full rack power loss does not erase any transducer configuration data; swapping the unit only requires physical reconnection with no software rework if total system length remains unchanged.
4. What warranty terms separate New Surplus inventory from refurbished alternatives?New Surplus cable assemblies carry a 12-month functional warranty covering triaxial impedance consistency, gold connector plating integrity, and FluidLoc seal performance. Refurbished cables typically offer only 3–6 month limited coverage and carry hidden risks of cracked FEP insulation, degraded connector locking tabs, and compromised fluid sealing that lead to drifting vibration readings during turbine thermal transients.
5. Why does New Surplus pricing sit higher than generic used/refurbished marketplace listings?All New Surplus cable assemblies complete mandatory QC validation: serial traceability cross-check against OEM production logs, full impedance and capacitance bench testing across the entire cable length, pull-load tensile testing to validate FluidLoc joint adhesion, connector lock cycle 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 axial position protection loops.
6. Can this cable mate with older 5mm standard 3300 series proximity probes?No, the ClickLoc connector pinout and triaxial impedance profile are exclusive to 8mm 3300 XL transducer systems. Older 5mm probe assemblies use incompatible 2-pin threaded connectors and require dedicated 330131 series extension cables. Verify with the OEM 3300 XL datasheet before cross-mixing transducer hardware to avoid permanent Proximitor input circuit damage.
7. Does the cable locally store vibration waveforms or long-term machine position trending logs?No, the unit is a fully passive analog transmission component with zero memory or signal processing hardware. All vibration amplitude, axial displacement, and Keyphasor 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 data storage or signal modification capability.
