• Detailed Part Number Breakdown:
  • 330908: Base Model - 3300 NSv Probe, 3/8-24 UNF thread, no armor
  • -00: Unthreaded Shank Length = 0 inch
  • -19: Overall Case Length = 1.9 inch
  • -10: Total Cable Length = 1.0 meter (39 inches)
  • -02: Connector Type = Miniature coaxial ClickLoc with standard cable
  • -05: Agency Approvals = Multiple (e.g., ATEX, IECEx)
• Linear Measurement Range: 1.5 mm (60 mils), valid from 0.25 to 1.75 mm from target.
• Recommended Installation Gap: 1.0 mm (40 mils) from the target surface.
• Scale Factor (Sensitivity): 7.87 V/mm (200 mV/mil) with a tolerance of +12.5%/-20%.
• Non-Linearity (DSL): Less than ±0.06 mm (±2.3 mils) across the full range.

Performance & Electrical Characteristics

• Frequency Response: 0 to 10 kHz, with a maximum roll-off of -3 dB using long cables.
• Probe DC Resistance: 4.2 Ohms ± 0.5 Ohms (for the standard 1.0m integrated cable).
• System Compatibility: This probe is fully interchangeable with older 3300 XL 8 mm Proximity Probes and 3300 RAM system components.
• Cable Specifications:
  • Extension Cable Resistance: Center Conductor: 0.220 Ω/m, Shield: 0.066 Ω/m.
  • Extension Cable Capacitance: 69.9 pF/m (typical).
  • Field Wiring: Use three-conductor shielded cable (16-24 AWG). Maximum run is 305m to the monitor.
• Minimum Target Size: 8.9 mm diameter. Use a 13 mm or larger target for optimal accuracy.

Robust Construction & Environmental Ratings

• Probe Tip: Made from chemically resistant Polyphenylene Sulfide (PPS).
• Probe Body: Constructed from durable AISI 304 Stainless Steel.
• Operating Temperature: -52°C to +177°C (-62°F to +351°F).
• Pressure Seal: Features a Viton O-ring for differential pressure sealing.
• Agency Approvals: The "-05" suffix indicates multiple international certifications for hazardous areas.

Mechanical Installation Guidelines

• Mount the probe to achieve the recommended 1.0 mm (40 mil) gap from the target.
• Probe Body Torque: Hand-tighten only; maximum is 0.56 N•m (5 in-lb).
• Connector Torque: For 3/8-24 thread, recommended torque is 7.5 N•m (66 in-lb).
• Thread Engagement: Do not engage more than 0.563 inches of the probe threads.
• Cable Handling: Maintain a minimum bend radius of 25.4 mm (1.0 inch).
• For small shafts under 13 mm, reduce the gap to minimize measurement error.

Frequently Asked Questions (FAQ)

• Can I use this NSv probe with my existing 3300 system? Yes, the 3300 NSv probe is a direct mechanical and electrical replacement for 3300 RAM probes.
• What is the main advantage over older probes? It offers significantly better chemical resistance for harsh environments like process compressors.
• How long can the cable be between the probe and monitor? You can use up to 305 meters (1000 feet) of field wiring with minimal signal loss.
• Is this probe suitable for small shafts? Yes, but for axial measurements on shafts under 13mm, carefully follow the gap-setting guidelines to ensure accuracy.
