- ✅ EMI/RFI shielded — armored jacket prevents signal noise in high-interference plant environments
- ✅ Guaranteed signal integrity — no impedance mismatch or calibration drift
- ✅ Traceability — full OEM documentation and certificates of conformance available
Typical Applications
- Steam and gas turbine shaft vibration monitoring
- Centrifugal compressor radial and axial displacement measurement
- Pump and motor bearing condition monitoring
- Rotating machinery protection systems in oil & gas, power generation, and petrochemical plants
- API 670-compliant machinery protection panels
System Compatibility
The 330930-040-02-00 extension cable is designed for use within the Bently Nevada 3300 Series proximity transducer system, which includes:
- Probes: 330103, 330104, 330105 (7.87 mm / 5 mm tip diameter)
- Proximitors/Drivers: 3300 XL proximitor modules (e.g., 330180, 330185)
- Monitors: 3500 Series rack-based machinery protection monitors
- Total cable system length: Probe cable + extension cable must equal system-calibrated total (typically 5 m, 9 m, or custom)
⚠️ Important: The total system cable length (probe + extension) must match the proximitor calibration. Mixing cable lengths without recalibration will cause measurement errors.
Selection Guide
Use the Bently Nevada 330930 part number structure to select the correct cable:
- 330930 — Extension cable base model for 3300 Series
- -040 — Cable length: 040 = 40 ft / 12.2 m (other options: 020, 060, 085, 100)
- -02 — Armor type: 02 = armored jacket (00 = standard)
- -00 — Connector/termination option
To select the right cable, confirm: (1) required cable run length, (2) probe model in use, (3) proximitor model and calibrated system length, (4) environmental requirements (armored vs. standard).

Replacement & Compatibility FAQ
Q: Can I use a 330930-040-00-00 instead of 330930-040-02-00?
A: The -00-00 variant uses a standard (non-armored) jacket. It is electrically equivalent but may not meet environmental protection requirements in high-vibration or high-EMI installations.
Q: What happens if I use the wrong cable length?
A: The 3300 Series system is calibrated for a specific total cable length. Using a different length without recalibrating the proximitor will result in incorrect gap voltage readings and measurement errors.
Q: Is this cable compatible with the 3500 Series monitors?
A: Yes — the 3300 Series transducer system (probe + extension cable + proximitor) outputs a standard -18 VDC signal compatible with Bently Nevada 3500 Series monitor inputs.
Q: Can Konmask.com supply a custom cable length?
A: Contact us for custom length requirements. We can source or advise on factory-calibrated custom assemblies.
Q: Do you provide a warranty?
A: Yes. All products sold through Konmask.com include a quality guarantee. Contact support for warranty terms.
