System Length Integration

• Critical Rule: Probe length + extension cable length = Proximitor total length.
• Example Calculation: 1.0m probe + 4.0m cable = 5.0m system total.
• Calibration Impact: Factory calibration assumes specific total length.
• Do Not Mix: Different cable lengths alter system response.
• Verification Step: Check Proximitor label for approved total length.
• Field Modification: Never cut or splice this cable.

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 optimal linearity.
• Voltage at Recommended Gap: Approximately -7 to -8 Vdc.

Field Wiring Guidelines

• Maximum Field Wiring Length: 305 meters (1,000 feet) 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 manual for high frequency effects.
• Noise Prevention: Keep field wiring away from power cables.

Tensile Strength Ratings

• Probe case to probe lead: 220 N (50 lb) maximum.
• Probe lead to extension cable connector: 220 N (50 lb) maximum.
• Probe case to stainless steel armor: 220 N (50 lb) maximum.
• Armor Pull Strength: Armor adds significant pull resistance.
• Installation Advice: Pull by armor or connector body, not the cable.
• Service Loop: Leave slack at both ends for strain relief.

Connector Care and Maintenance

• Connector Type: 3300 NSv series gold-plated brass.
• Armor Termination: Armor securely crimped to connector body.
• Keep Clean: Dirt and moisture cause signal degradation.
• Hand-Tight Only: Never use tools on connector coupling nut.
• Inspect Before Use: Check for bent pins or damaged threads.

• Compatible Proximitor: 3300 NSv Proximitor Sensor.
• Compatible Rack: 3500 Series monitoring systems.
• Not Compatible With: Standard 3300 XL probes (different connector).
• Verification: Look for NSv marking on probe and proximitor.

When to Choose Armored Cable (Option 01)

• Direct Burial: Armor protects against soil and rocks.
• Exposed Runs: Cable not inside conduit needs armor.
• High Traffic Areas: Prevents damage from foot or vehicle traffic.
• Abrasion Risk: Sharp edges or vibrating surfaces.
• Rodent Prone Areas: Stainless steel resists gnawing.
• Outdoor Installations: FEP jacket with armor provides UV protection.

Frequently Asked Questions

• Q: What is the difference between option 01 and option 03 for this cable?
  A: Option 01 includes stainless steel armor with FEP outer jacket for maximum protection. Option 03 has no armor and includes a connector protector. Choose 01 for exposed or buried installations.
• Q: What does agency approval code 05 (Multiple Approvals) include?
  A: Code 05 typically includes CSA for North America, ATEX for Europe, and IECEx for international hazardous locations. This cable is certified for global use in Class I, Division 2 areas.
• Q: Can I use the 330930-040-01-05 with standard 3300 XL probes?
  A: No. This cable is for 3300 NSv systems only. NSv uses different connector design and 75Ω impedance. Using with 3300 XL will cause signal errors and may damage connectors.
• Q: How do I calculate total system length with this armored cable?
  A: Add probe length plus extension cable length. Example: 0.5m probe + 4.0m cable = 4.5m total. This total must match the Proximitor Sensor calibration label exactly.
• Q: What temperature range does the armored 330930-040-01-05 handle?
  A: The cable handles -51°C to +177°C (-60°F to +351°F). The stainless steel armor and FEP jacket maintain full performance across this entire range, suitable for turbines and compressors.
