Why Choose the Original Model
- System-certified signal path: Factory-matched impedance and capacitance ensure the 3300 NSv system meets API 670 calibration standards out of the box.
- Armored construction: Stainless steel armor protects against mechanical damage in turbine halls, compressor skids, and pump stations.
- Wide temperature tolerance: Rated to -55°C / +125°C, suitable for cryogenic and high-heat process environments.
- Traceability: OEM part numbers provide full documentation trail for ISO/ATEX compliance audits.
- Plug-and-play replacement: No recalibration required when replacing like-for-like within the 3300 NSv system.
Typical Applications
- Gas turbine shaft vibration and position monitoring
- Steam turbine radial and axial displacement measurement
- Centrifugal compressor rotor dynamics monitoring
- Pump and motor bearing vibration surveillance
- Petrochemical plant rotating machinery protection systems
- Power generation and oil & gas upstream/downstream facilities
System Compatibility
The 330930-040-05-05 extension cable is designed to operate within the complete Bently Nevada 3300 NSv Proximity Transducer System, which includes:
- Probe: 330780 / 330900 series 8 mm proximity probes
- Proximitor Sensor: 330180 / 330190 NSv Proximitor® Sensor
- Monitoring System: 3500 Series Machinery Protection System (MPS)
- Interconnect: This extension cable (330930-040-05-05)
Substituting cables from other series (e.g., 3300 XL, 7200 series) requires re-verification of system gain and scale factor — consult Bently Nevada documentation or contact Konmask.com engineering support.
Selection Guide
Use the following criteria to select the correct extension cable for your application:
- Cable Length: Measure the distance from probe tip to proximitor housing. Total system cable length (probe + extension) must not exceed the system’s specified range (typically 5 m or 9 m). The suffix -05 in 330930-040-05-05 denotes 5 m.
- Connector Style: Confirm MIL-C-17 coaxial connectors are required. Some installations use BNC or SMA — verify before ordering.
- Armor Requirement: Select armored (-05-05) for exposed or high-traffic areas; non-armored (-00-05) for protected conduit runs.
- Temperature Rating: Standard -55°C to +125°C covers most applications; consult Bently Nevada for extreme environments.
- Hazardous Area Classification: Confirm ATEX/IECEx zone requirements align with the system’s certified configuration.

Replacement & Compatibility FAQ
Q: Can I use a 330130 series cable as a direct replacement for the 330930-040-05-05?
A: The 330130 series is designed for the 3300 XL 8 mm system. While physically similar, system gain and scale factor may differ. Re-verification is required before substitution in a live system.
Q: What happens if the extension cable length exceeds the system specification?
A: Exceeding the total cable length limit alters the system’s capacitance and gain, causing measurement errors. Always keep total cable length (probe + extension) within the Bently Nevada-specified range for your proximitor model.
Q: Is the 330930-040-05-05 compatible with the 3500 Machinery Protection System?
A: Yes, when used as part of the complete 3300 NSv transducer system (probe + extension + proximitor), it interfaces correctly with the 3500 MPS rack.
Q: Do you supply certificates of conformance?
A: Yes. CoC and inspection records are available for all units. Request at time of order.
Q: Can Konmask.com source discontinued or long-lead Bently Nevada parts?
A: Yes. We specialize in hard-to-find and obsolete automation components. Submit an RFQ and our sourcing team will respond within 24 hours.
