Description
Product Overview
Part Number: 330130-085-00-CN Manufacturer: Bently Nevada (Baker Hughes) Product Series: 3300 XL 8mm Transducer System Extension Cable Type: Standard triaxial extension cable, USA manufactured. This 8.5-meter extension cable is designed to connect 3300 XL 8mm proximity probe to the 3300XL proximitor sensor. It transmits eddy current displacement signals for shaft vibration, thrust position and keyphasor measurement on steam turbines, centrifugal compressors, generators and large process pumps. It is a passive component of the complete TSI machinery protection system, compliant with API 670 standard. The sum of probe integral cable length plus this extension cable length must match the calibrated total length requirement of the proximitor.

Engineer Notes
- Critical rule: Probe integral cable length + extension cable length must equal the total electrical length specified for the matched 3300XL proximitor. Mismatched total length will cause scale factor error.
- This cable only works with 3300XL 8mm probe system; NOT compatible with 11mm, NSv or older 3300 series transducer systems.
- Do not splice, cut or modify the triaxial cable or factory connectors. Any alteration destroys impedance matching and voids calibration and warranty.
- Handle connectors carefully; avoid dirt, moisture or pin damage. Keep connectors capped when not connected.
- CN suffix: China certified variant, same electrical performance as standard 00 version.
- For heavy abrasion environments, select armored cable variant instead of this standard 00 type.
- Route cable away from high voltage power cables to reduce electrical noise interference.
Pre-Shipment Test Protocol
- Continuity and insulation resistance test of full cable
- Impedance and signal integrity check
- Connector pin continuity & leakage test
- Visual inspection: cable jacket, connector shell, pins and labeling
- Part number, label and marking verification
- Anti-static & shockproof packaging inspection
Buyer FAQ
Q: Is 330130-085-00-CN new original? A: We supply brand new original Bently Nevada units, 12-month warranty, factory test certificate available on request.
Q: What does 085 mean in part number? A: 085 represents cable length 8.5 meters.
Q: Can I combine this cable with any 3300XL proximitor? A: No. The combined length of probe + extension cable must match the proximitor calibrated length. Always verify total length before ordering.
Q: What does CN suffix mean? A: CN is Chinese market certification variant; all electrical parameters are identical to standard 00 version.
