🔌 Precision Extension Cable for 3300 NSv Proximity Systems
The Bently Nevada 330930-060-00-05 is a 6-meter (19.7 ft) extension cable engineered for the 3300 NSv proximity transducer system. This non-armored configuration delivers optimal signal transmission in controlled environments where mechanical protection is secondary to flexibility and ease of installation.
⚠️ Critical System Length Matching
IMPORTANT: The combined length of your proximity probe + this extension cable MUST equal the total system length programmed into your Proximitor Sensor. Mismatched lengths cause measurement errors and false alarms.
Example: 3300 NSv 5mm probe (0.5m) + this 6m extension = 6.5m total system → Proximitor must be configured for 6.5m
✅ Ideal Applications
- Indoor turbine monitoring
- Climate-controlled compressor rooms
- Clean manufacturing environments
- Laboratory test stands
❌ Not Recommended For
- High-traffic walkways
- Outdoor/weather-exposed areas
- Chemical splash zones
- Heavy machinery proximity

⚡ Real-World Deployment Scenarios
🏭 Scenario 1: Power Plant Steam Turbine
Challenge: Monitor bearing vibration on a 50MW turbine in a climate-controlled turbine hall.
Solution: Install 3300 NSv 5mm probes at each bearing with 6m extension cables routing through overhead cable trays to centralized monitoring rack. The non-armored design provides flexibility for tight bends around structural steel while maintaining signal integrity across the 6.5m total system length.
🔬 Scenario 2: Aerospace Test Stand
Challenge: Measure shaft displacement on jet engine test rig with frequent sensor repositioning.
Solution: Use 6m extensions to allow probe relocation without rewiring proximitor rack. The lightweight, flexible cable simplifies reconfiguration during different test protocols while the 05 certification meets facility safety requirements.
⚙️ Scenario 3: Pharmaceutical Compressor Monitoring
Challenge: Vibration monitoring in clean room environment with strict contamination controls.
Solution: Non-armored cable eliminates metal particle shedding risk. The 6m length bridges the distance from compressor (inside clean room) to monitoring equipment (outside controlled area) through sealed wall penetrations.
🔗 System Compatibility Matrix
| Compatible Probes | 3300 NSv 5mm, 8mm proximity probes (all thread types) |
| Compatible Proximitors | 330930 Proximitor Sensor (must match total system length) |
| Connector Type | Bayonet-style quick-disconnect (probe end & proximitor end) |
| System Voltage | -24 VDC (standard Bently Nevada configuration) |
📏 Length Selection Guide
Why 6 meters? This length is optimal for:
- ✓ Typical machine-to-control-room distances in industrial facilities (15-25 feet)
- ✓ Routing through cable trays with vertical/horizontal transitions
- ✓ Balancing signal quality vs. installation flexibility
- ✓ Minimizing capacitance-induced measurement drift
💡 Pro Tip: For distances >8m, consider using a proximitor-mounted configuration to reduce cable capacitance effects on measurement accuracy.
🛠️ Installation Best Practices
- Pre-Installation Verification: Measure DC resistance (should be <2Ω core-to-core) to confirm cable integrity
- Routing Strategy: Maintain 300mm (12") separation from AC power cables >120V to prevent EMI coupling
- Bend Management: Use cable guides at 90° turns; never exceed 50mm minimum bend radius
- Connector Protection: Apply dielectric grease to bayonet connectors in humid environments (>80% RH)
- Grounding: Connect cable shield to proximitor chassis ground only (single-point grounding prevents ground loops)
- Documentation: Label both ends with total system length for future maintenance reference
⚠️ Common Installation Mistakes to Avoid
| Mistake | Consequence | Prevention |
|---|---|---|
| Mismatched system length | ±2mm measurement error | Verify probe + cable = proximitor setting |
| Over-tightening connectors | Damaged bayonet pins | Hand-tighten only; no tools required |
| Parallel routing with VFD cables | High noise floor (>50mV) | Cross power cables at 90° only |
| Exposing to <-34°C sustained | Pressure seal failure | Use heated enclosures in arctic climates |
