• Probe DC Resistance: 4.0 Ohms ± 0.5 Ohms (for the integrated 0.5-meter cable).
• System Compatibility: Fully interchangeable with legacy systems like the 3300 XL 8 mm Proximity Probes and 3300 RAM.
• Electrical System Parameters:
  • Extension Cable Resistance: Center: 0.220 Ω/m, Shield: 0.066 Ω/m.
  • Extension Cable Capacitance: Typically 69.9 pF per meter.
  • Field Wiring: Supports up to 305 meters of three-conductor shielded cable.
• Target Requirements: Minimum 8.9 mm diameter; 13 mm or larger is recommended.

Rugged Design & Environmental Specifications

• Probe Tip Material: Chemical-resistant Polyphenylene Sulfide (PPS).
• Probe Case: Constructed from durable AISI 304 Stainless Steel.
• Operating Temperature: Broad range from -52°C to +177°C (-62°F to +351°F).
• Sealing: Utilizes a Viton O-ring to seal against differential pressure.
• Certifications: The "-05" suffix indicates compliance with multiple international safety standards.

Frequently Asked Questions (FAQ)

• Will this probe work with my older 3300 monitoring system? Yes. The 3300 NSv probe is a direct mechanical and electrical replacement for previous 3300 RAM probes.
• What is the advantage of the 4.6-inch case length? It allows for secure installation in deeper mounting holes or through thicker housing walls.
• What is the maximum cable distance supported? The system supports field wiring up to 305 meters (1000 feet) between the sensor and monitor.
• Is this sensor suitable for small diameter shafts? Yes, but for precise axial measurement on shafts under 13mm, follow the specific gap adjustment guidelines.
