Vibration Monitoring Solution – Bently Nevada 330854-040-25-CN | 3300 XL Series
Where This Product Is Used
The Bently Nevada 330854-040-25-CN is a 25-foot (7.62 m) extension cable engineered for the 3300 XL Proximity Transducer System. It bridges the gap between the proximity probe and the Proximitor® sensor in high-vibration, high-temperature industrial environments. Typical deployment sites include:
- Steam & Gas Turbines – shaft radial vibration and axial position monitoring on power generation units
- Centrifugal Compressors – continuous rotor orbit and eccentricity measurement in petrochemical plants
- Pumps & Fans – bearing health surveillance in water treatment and HVAC systems
- Gearboxes & Expanders – torsional and lateral vibration detection in refinery and LNG facilities
- Marine Propulsion Systems – shaft monitoring in confined machinery spaces requiring precise cable routing
Wherever rotating machinery demands API 670-compliant vibration protection, the 330854-040-25-CN delivers the signal integrity required for reliable trip and alarm functions.

Why Engineers Specify This Model
- Exact Length Matching: The 25 ft (040 = 40 cm probe + 25 ft cable) configuration minimizes signal loss and eliminates field splicing, preserving system accuracy to ±0.5%.
- Drop-in Compatibility: Designed exclusively for the 3300 XL ecosystem — no re-calibration required when replacing a like-for-like cable.
- EMI/RFI Shielding: Double-shielded coaxial construction rejects electrical noise in VFD-dense and high-voltage switchgear environments.
- Chemical Resistance: PTFE jacket withstands hydrocarbon vapors, lubricating oils, and cleaning solvents common in refinery service.
- Reduced Downtime: Pre-terminated, factory-tested connectors allow hot-swap replacement during planned outages without re-termination labor.

Application-Specific FAQ
Q: Can I use the 330854-040-25-CN with an older 3300 (non-XL) probe?
A: The cable connector is physically compatible, but system performance and scale factor accuracy are only guaranteed within the 3300 XL matched-system configuration. Mixing generations may introduce calibration offsets.
Q: What is the maximum total cable length for a 3300 XL system?
A: Bently Nevada specifies a maximum combined probe + extension cable length. For 8 mm probes, the typical maximum is 9 m (≈30 ft) total. The 25 ft extension is designed for use with short integral-cable probes to stay within this limit.
Q: Is this cable suitable for cryogenic service?
A: The standard 330854-040-25-CN is rated to –40 °C. For cryogenic applications below –40 °C, consult Bently Nevada / Baker Hughes for low-temperature variants.
Q: Do you supply calibration certificates?
A: Factory calibration data is available for new units. For surplus stock, we provide inspection reports. Contact us to discuss documentation requirements before ordering.
Q: Can Konmask supply the complete 3300 XL system (probe + cable + Proximitor®)?
A: Yes. We can source and supply complete matched sets. Contact our team with your system tag number and we will configure the correct BOM.
