Product Introduction
Bently 330130-080-02-CN is the 8.0 m extension cable option for the 3300 XL proximity probe system designed to prolong the distance between the probe tip and the preamplifier or monitor. It preserves the probe’s electrical characteristics and shielding so the 3300 monitor receives a clean, calibrated signal for vibration, displacement, or speed measurements.
This cable is selected when original probe cable lengths are insufficient or when rerouting is required for plant layout reasons; using an OEM-compatible 3300 XL extension helps avoid noise, grounding issues, and calibration drift common with non‑matched cabling.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No probe signal at monitor | Open cable, damaged connector, or poor termination | ✅ High | Inspect cable ends and connectors visually; measure continuity of center conductor and shield with multimeter | Replace or reseat cable; verify connector pin mapping matches 3300 XL preamp |
| Excessive noise or unstable reading | Poor shield termination or ground loop introduced by extension | ✅ High | Check shield continuity end-to-end and verify single-point grounding; view signal on scope | Re-terminate shield per 3300 XL guidance; avoid bonding shield at multiple points |
| Change in sensitivity / offset | Incorrect extension type or damaged coax altering probe impedance | ✅ High | Compare DC resistance and capacitance to known-good cable; check calibration bias voltage at preamp | Swap for a known-good OEM cable; re-calibrate system if necessary |
| Intermittent dropouts | Connector fretting, water ingress, broken conductor | ✅ High | Wiggle test at both ends while monitoring signal; inspect for corrosion or pin damage | Replace cable and ensure CableLoc/strain relief is correctly installed |
| Short between center and shield | Cable breach or crushed cable along run | ✅ High | Measure insulation resistance; visually inspect entire cable route for damage | Remove cable from service and replace; protect routing against pinch points |
| Probe reading reduced range | Using cable for mismatched probe family (5 mm/11 mm) | ⚠️ Medium | Confirm probe and cable family are both 8 mm 3300 XL items | Do not mix probe families; replace with correct cable type |
Final note: ask the supplier for photos of the cable ends, confirmation of OEM part marking, and any available test reports before purchase to minimize fitment risk.
Frequently Asked Questions (FAQ)
Q: What does the “080” in 330130-080-02-CN mean?
A: The “080” denotes an 8.0 m cable length option (approx. 26.2 ft), standard nomenclature in Bently part numbering for the 3300 XL cable family.
Q: Is 330130-080-02-CN compatible with all 3300 XL probe tips?
A: It is compatible with 8 mm 3300 XL probe tips (the common 8 mm family); do not use this cable with 5 mm or 11 mm probe families without verifying mechanical and electrical compatibility.
Q: Can I splice this cable in the field to shorten it?
A: Avoid splicing. Splices compromise impedance and shielding and can introduce noise or change calibration. Use factory lengths or order a custom-length OEM cable.
Q: How do I verify the cable before installing on critical machinery?
A: Verify continuity center/shield, insulation resistance, and visually inspect connectors and CableLoc strain relief; if possible bench-test with a known-good probe and preamplifier and request vendor test documentation.
Q: Is this cable suitable for high-temperature environments?
A: 3300 XL cables are typically rated for industrial temperatures; confirm the exact temperature rating and jacket specification with the seller before use in high-temperature applications.
Q: Why buy the OEM 330130-080-02-CN instead of a generic cable?
A: OEM cables preserve probe impedance, shielding, and mechanical retention features (CableLoc) that prevent signal degradation and false alarms in precision shaft‑monitoring systems. Generic alternatives risk introducing noise, ground loops, or altered calibration.
Q: What warranty or test evidence should I demand?
A: Request a visual inspection record, continuity/insulation checks, and evidence of OEM part number labeling; for surplus stock, insist on a minimum functional warranty (90 days recommended, 6–12 months preferred for critical spares).
