Description
Product Overview
Bently Nevada 330130-040-00-CN is a 4-meter non-armored coaxial extension cable for the 3300 XL 8mm eddy current proximity transducer system. It connects the 8mm proximity probe to the matched Proximitor preamplifier, transmitting high-frequency signals used to measure shaft radial vibration, gap and axial position for 3500 series machinery monitoring racks. This assembly uses ClickLoc miniature coaxial connectors with controlled capacitance to preserve transducer linearity. The 00 suffix denotes standard cable without connector protectors; CN suffix includes regional certification documentation. OEM production has ended; available stock consists of surplus or refurbished tested replacement units for turbomachinery protection and condition monitoring systems.

Engineer Notes
- This cable works exclusively with standard 3300 XL 8mm probe assemblies. Sum of probe length plus extension cable length must match the factory-calibrated total length of the paired Proximitor sensor. Mismatched total length alters scale factor and creates measurement errors or false machine alarms.
- ClickLoc connectors are precision coaxial components. Do not over-twist, pull or contaminate contact surfaces during installation. Damaged connectors lead to intermittent gap readings.
- Route the coaxial cable separately from high-current AC power and relay wiring. Electrical interference disturbs high-frequency eddy current signals and degrades transducer linearity.
- Maintain the minimum cable bend radius during routing. Sharp bends deform internal coaxial structure and change capacitance, invalidating factory transducer calibration.
- Non-armored jacket requires rigid conduit in areas with abrasion, mechanical impact or flying debris. Secure cable supports to reduce vibration fatigue at connector junctions.
- Apply ESD controls while handling. Inspect connector sealing surfaces before installation. After replacement, perform gap calibration and verify vibration and position readings on the monitoring rack.
Pre-Shipment Test Protocol
- Visual inspection: Check FEP jacket, ClickLoc connectors for cuts, cracks, dents, corrosion or deformed contact pins.
- Continuity test: Verify center conductor continuity and confirm no short circuit between center conductor and shield.
- Capacitance measurement: Confirm total cable capacitance stays within factory tolerance band.
- Insulation resistance test: Validate high insulation resistance between inner conductor and shield.
- Bench functional test: Pair cable with known-good 3300XL 8mm probe and matched Proximitor, check gap response and linearity across measurement range.
- Save test logs and photos for QA records.
Buyer FAQ
Q: Can I swap 330130-040-00-CN with other length 3300XL extension cables? A: Connector style is identical, but total transducer assembly length changes Proximitor calibration. Confirm full probe + extension length before cutover.
Q: Is this cable compatible with 3300 XL NSv probe systems? A: No. This is standard 3300XL 8mm cable, not NSv series. Do not mix standard XL and NSv components.
Q: What does CN suffix mean? A: CN indicates regional certification documentation is included with the cable.
Q: Are proximity probe or Proximitor sensor included? A: Only the 4m standard extension cable is supplied. Probe and Proximitor sold separately unless noted on your quote.
