⚡ High-Performance Extension Cable for Precision Vibration Sensing
The Bently Nevada 330854-080-24-CN represents the gold standard in proximity probe extension cables, specifically engineered for the 3300 XL 25mm sensor system. This 8-meter (26.2 feet) high-temperature FluidLoc cable extends your monitoring reach in the most demanding industrial environments where standard cables fail.
🎯 Why This Cable Matters for Your Operation
Temperature Extremes: Operating range from -35°C to +200°C (-31°F to +392°F) ensures reliable signal transmission in cryogenic pumps, steam turbines, and furnace-adjacent machinery where conventional cables degrade.
Signal Integrity: Precision-controlled 75Ω triaxial construction with 69.9 pF/m capacitance maintains measurement accuracy within ±0.92mm (±36 mils) across the full temperature spectrum—critical for detecting early bearing faults.
Fluid Resistance: FluidLoc technology prevents oil, coolant, and process fluid migration along the cable core, eliminating false alarms caused by contamination-induced impedance changes.
🔬 Engineering Specifications
Cable Configuration: 330854-AAA-BB-CC
| Code Position | This Model | Available Options |
|---|---|---|
| AAA - Length | 080 = 8.0 meters (26.2 ft) | 040 = 4.0m (13.1 ft) | 080 = 8.0m (26.2 ft) |
| BB - Cable Type | 24 = High-Temp FluidLoc | 24 = Standard | 25 = Armored |
| CC - Certifications | CN = China Approvals | 00 = None | 05 = Multi-Agency |
Electrical Performance Metrics
| DC Resistance (Core) | 2.0 ± 0.5 ohms @ 8m length |
| DC Resistance (Jacket) | 0.6 ± 0.2 ohms @ 8m length |
| Capacitance | 69.9 pF/m (21.3 pF/ft) typical |
| Impedance | 75 Ω triaxial (precision matched) |
| Temperature Stability | DSL drift ≤ ±0.92mm over full range |
Physical Construction
| Insulation Material | Perfluoroalkoxyethylene (PFA) - chemically inert |
| Cable Architecture | 75Ω triaxial with FluidLoc barrier |
| Mass per Meter | 140 g/m (1.5 oz/ft) |
| Operating Temp | -35°C to +200°C continuous |
| Storage Temp | -35°C to +200°C |
🏭 Real-World Application Scenarios
Steam Turbine Monitoring: Install between high-temperature bearing housings (+180°C) and control room proximitors. The 8m length allows routing through cable trays away from radiant heat zones while maintaining signal fidelity for critical thrust position measurements.
Compressor Train Protection: Connect 3300 XL probes on multi-stage compressors to centralized monitoring racks. FluidLoc construction prevents process gas condensate from migrating into proximitor housings, eliminating nuisance trips.
Offshore Platform Installations: Bridge the distance between subsea pump probes and topside control systems. PFA insulation resists saltwater corrosion and UV degradation in exposed cable runs.
Petrochemical Reactor Monitoring: Monitor agitator shaft vibration in vessels with ambient temperatures exceeding +150°C. The cable's thermal stability ensures accurate readings during process upsets and emergency shutdowns.
⚙️ Installation & Compatibility Requirements
⚠️ Critical Length Calculation: Total system length = Probe length + Extension cable length. This MUST match your Proximitor Sensor's specified total length. Mismatched lengths cause calibration errors and false alarms.
Example: If using a 330103-00-08-XX probe (8mm length) with this 8m extension, your Proximitor must be configured for 8.008m total system length.
Compatible Proximitor Models:
- 3300 XL 25mm Proximity Transducer System
- 3300 XL NSv Proximity Sensor (25mm tip diameter)
- 3300 XL ETR Reverse Mount Probes (25mm series)
Installation Best Practices:
- Maintain minimum 50mm (2") bend radius to prevent core damage
- Route away from high-voltage power cables (>300mm separation)
- Use cable glands rated for operating temperature range
- Verify DC resistance after installation to confirm integrity
- Label both ends with system length for future maintenance
📈 System Performance Validation
Temperature Compensation Testing:
- Probe at -35°C to +120°C, cable/proximitor at 0°C to +45°C: DSL ≤ ±0.92mm
- Cable/proximitor at -35°C to +65°C, probe at 0°C to +45°C: DSL ≤ ±0.92mm
This dual-range validation ensures accurate measurements regardless of which component experiences temperature extremes—essential for applications with localized heating or cooling.
🔍 Common Issues & Solutions
| Symptom | Probable Cause | Solution |
|---|---|---|
| Erratic readings | Fluid ingress in connector | Verify FluidLoc seal integrity; replace if compromised |
| Offset drift | Temperature mismatch | Confirm total system length matches proximitor setting |
| High noise | EMI coupling | Reroute away from VFDs/power cables; check grounding |
| Open circuit alarm | Core break from overbending | Inspect for kinks; measure DC resistance |
