Description
Product Overview
Bently Nevada 330130-045-00-00 is a 4.5-meter non-armored coaxial extension cable designed 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 vibration, radial gap and axial position. It feeds measurement data to 3500 series monitoring racks on steam turbines, centrifugal compressors, generators and other critical rotating assets. This assembly uses ClickLoc miniature coaxial connectors with controlled capacitance to preserve transducer linearity. The suffix 00-00 denotes standard configuration, no extra protective hardware and no certified documentation package. 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 pairs only with standard 3300 XL 8mm probes. The combined length of probe plus extension cable must match the calibrated total length of the Proximitor. Mismatched total length changes scale factor and introduces measurement error or false alarms.
- ClickLoc connectors are precision components. Do not over-tighten, pull or contaminate contact surfaces. Damaged connectors cause intermittent gap readings.
- Separate this coaxial cable from high-current AC and relay wiring. Electrical noise disturbs eddy current signals and degrades linearity.
- Maintain the minimum bend radius during routing. Sharp bends damage internal coaxial layers and alter capacitance, voiding the factory transducer calibration.
- Non-armored jacket requires conduit in areas with abrasion, mechanical impact or heavy debris. Use cable supports to reduce vibration stress at connector joints.
- Apply ESD controls while handling. Inspect connector surfaces before installation. After replacement, run gap calibration and verify vibration and position readings on the monitoring rack.
Pre-Shipment Test Protocol
- Visual inspection: Check outer jacket, ClickLoc connectors for cuts, cracks, dents, corrosion or deformed contact pins.
- Continuity test: Confirm center conductor continuity and no short between center conductor and shield.
- Capacitance measurement: Verify total cable capacitance is within factory tolerance.
- Insulation resistance test: Confirm high insulation resistance between inner conductor and shield.
- Bench functional test: Mate cable with known-good 3300XL 8mm probe and matching Proximitor. Validate gap response and linearity across the full measurement range.
- Save test logs and photos for QA records.
Buyer FAQ
Q: Can I replace this with a different length 3300XL extension cable? A: The connector is physically compatible, but changing total transducer length requires matching Proximitor calibration. Confirm full probe + cable length before replacement.
Q: Can I use this cable with 3300XL NSv probes? A: No. This is standard 3300XL 8mm cable. NSv transducers require dedicated NSv series components.
Q: What does suffix 00-00 mean? A: Standard version without connector protective boots, no certified documentation package included.
Q: Does this include proximity probe and Proximitor? A: Only the 4.5m extension cable is supplied. Probe and Proximitor sold separately unless stated on your quote.
