Vibration Monitoring Solution – Bently Nevada 330904-00-18-10-01-05 | 3300 Series Extension Cable
The Bently Nevada 330904-00-18-10-01-05 is an 18-inch (457 mm) extension cable engineered for use within the 3300 Series Proximity Transducer System. It serves as the critical signal-path link between the proximity probe and the proximitor/driver, enabling accurate, low-noise vibration and position measurement in rotating machinery applications.
At Konmask.com, we supply this cable as part of our verified industrial automation inventory — sourced through established channels and inspected before dispatch.
Where This Product Is Used

Application-Specific FAQ
Q: Can I use the 330904-00-18-10-01-05 with a 3300 XL 11 mm or 14 mm probe?
A: The extension cable is electrically compatible with all 3300 XL probe sizes (8 mm, 11 mm, 14 mm) provided the connector type matches.
Q: What happens if I use a non-OEM extension cable?
A: Non-OEM cables with incorrect impedance will shift the probe system sensitivity, causing calibration errors in the monitor — a critical safety risk on turbomachinery.
Q: Is 18 inches the only length available?
A: No. Bently Nevada offers extension cables in multiple lengths. The -18- in the part number denotes 18 inches. Contact us if you need a different length.
Q: Do you supply cables for ATEX Zone 1 / Zone 2 installations?
A: Yes. For hazardous area installations, additional Zener barriers or galvanic isolators are required. Contact us with your zone classification.
Q: Can you provide a Certificate of Conformance?
A: Yes. CoC documentation is available upon request for all stocked items.
Q: What is the lead time for urgent orders?
A: In-stock items ship within 1-3 business days. For urgent requirements, contact support@konmask.com directly.
