System Length Integration Rules

• Critical Rule: Probe length + extension cable length = Proximitor total length.
• Example with 6.5m cable: 1.0m probe + 6.5m cable = 7.5m system total.
• Shorter probe option: 0.5m probe + 6.5m cable = 7.0m system total.
• Calibration impact: Factory calibration assumes specific total length.
• Do not mix lengths: Using wrong cable changes system response.
• Verification: Check Proximitor label for approved total length.

Linear Range and Gap Settings

• Linear Range: 1.5 mm (60 mils) total measurement span.
• Range Start: 0.25 mm (10 mils) from target surface.
• Range End: 1.75 mm (70 mils) from target surface.
• Voltage at start: Approximately -1 Vdc.
• Voltage at end: Approximately -13 Vdc.
• Recommended Gap: 1.0 mm (40 mils) for best linearity.
• Voltage at recommended gap: Approximately -7 to -8 Vdc.

Field Wiring Guidelines

• Maximum field wiring: 305 meters (1,000 feet) from proximitor to monitor.
• Recommended cable: Three-conductor shielded triad.
• Wire gauge range: 0.2 to 1.5 mm² (16 to 24 AWG).
• With ferrules: 0.25 to 0.75 mm² (18 to 23 AWG).
• Frequency rolloff: See Figures 16 and 17 in product manual.
• Noise reduction: Keep field wiring away from power cables.

Unarmored Design Benefits (Option 03)

• Lighter weight: Easier to handle than armored version.
• More flexible: Bends tighter for conduit pulls.
• Lower cost: No stainless steel armor reduces price.
• Connector protector included: Plastic cover for storage.
• Best for conduit: Conduit provides physical protection.
• Indoor use: Suitable for clean, protected environments.

Connector Protector Information

• Included: Plastic protector screws onto connector.
• Purpose: Prevents dirt and moisture ingress during storage.
• Protects pins: Keeps gold-plated contacts clean.
• Use when disconnected: Install protector on both ends.
• Remove before connecting: Protector must come off for installation.
• Replace if lost: Generic protectors available from Bently Nevada.

Tensile Strength Ratings

• Probe case to probe lead: 220 N (50 lb) maximum.
• Probe lead to extension cable connector: 220 N (50 lb) maximum.
• Without armor: Same ratings apply to unarmored cable.
• Installation advice: Pull by connector body, not cable jacket.
• Service loop: Leave slack at both ends for strain relief.
• Avoid sharp bends: Minimum bend radius is 10x cable diameter.

Connector Care and Maintenance

• Keep connectors clean: Dirt causes signal noise and drift.
• Use protector when disconnected: Always install for storage.
• Inspect before each connection: Look for bent pins or damage.
• Hand-tighten only: Never use pliers or wrenches on coupling nut.
• Replace if damaged: Damaged connectors cause intermittent signals.

• Compatible Probes: 3300 NSv series proximity probes only.
• Compatible Proximitor: 3300 NSv Proximitor Sensor.
• Compatible Rack: 3500 Series monitoring systems.
• Not compatible with: Standard 3300 XL probes.
• Verification: Look for NSv marking on all components.

Frequently Asked Questions

• Q: Why would I choose the 6.5 meter 330930-065-03-00 over a shorter cable?
  A: Use this longer cable when your proximitor mounts farther from the probe. Total system length (probe + cable) must match the Proximitor calibration. This 6.5m cable works with 0.5m or 1.0m probes for 7.0m or 7.5m total systems.
• Q: What does option 03 (no armor, with connector protector) mean for installation?
  A: Option 03 means the cable has no stainless steel armor but includes a plastic connector protector. Use this cable inside conduit where the conduit provides physical protection. The protector keeps connectors clean during storage and shipping.
• Q: Can I use the 330930-065-03-00 in hazardous locations?
  A: No. Agency approval code 00 means no hazardous location certifications. For Class I, Division 2 areas, order code 05 (Multiple Approvals) instead. Code 00 is for safe area installations only.
• Q: What temperature range does this 6.5 meter cable handle?
  A: The FEP insulation handles -51°C to +177°C (-60°F to +351°F). The unarmored design maintains flexibility at low temperatures and integrity at high temperatures, suitable for turbine and compressor environments.
• Q: How do I calculate total system length with this 6.5m cable?
  A: Add your probe length to 6.5 meters. Example: 0.5m probe + 6.5m cable = 7.0m total. Example 2: 1.0m probe + 6.5m cable = 7.5m total. Check your Proximitor label for the approved total length before ordering.
