Bently Nevada 330904 NSv Probe 3300 Series 330904-09-17-05-01-05

Bently Nevada 3300 NSv Proximity Probe 330904-09-17-05-01-05 with 90mm Unthreaded Length

Core Technical Specifications

• Measurement Range: The system provides a linear range of 1.5 mm (60 mils), operating from 0.25 mm to 1.75 mm from the target surface. We recommend a gap setting of 1.0 mm (40 mils) for optimal performance.
• Sensitivity and Accuracy: This 3300 NSv Probe delivers an Incremental Scale Factor of 7.87 V/mm (200 mV/mil) including interchangeability error. The Deviation from Best Fit Straight Line remains less than ±0.06 mm (±2.3 mils).
• Electrical Characteristics: The 0.5 meter probe length features a DC resistance of 4.0 ± 0.5 ohms between conductors. Extension cable specifications show center conductor resistance of 0.220 Ω/m and capacitance of 69.9 pF/m.
• Frequency Response: The system maintains 0 to 10 kHz response (+0, -3 dB typical) with up to 305 meters of field wiring between sensor and monitor.
• Environmental Tolerance: The probe operates from -52°C to +177°C with a PPS tip and AISI 304 stainless steel case for excellent durability in harsh conditions.

Mechanical Installation Specifications

• Mounting Configuration: The unit uses M8x1 probe case thread with maximum engagement length of 12 mm. This configuration includes 90mm unthreaded length (-09 option) and 170mm overall case length.
• Torque Requirements: Install finger tight with maximum torque of 0.56 N•m (5 in•lb) for the probe tip. Connector-to-connector torque should be 5.1 N•m (45 in•lb) recommended.
• Wiring Specifications: Field wiring requires three-conductor shielded triad cable from 0.2 to 1.5 mm². You can extend wiring up to 305 meters to the 3300 XL NSv Proximitor Sensor.
• Mechanical Limits: Minimum bend radius is 25.4 mm (1.0 in) even with stainless steel armor. The probe seals differential pressure using a Viton O-ring.

Connector and Cable Details

• Connector Type: The 330904-09-17-05-01-05 includes a miniature coaxial ClickLoc connector with connector protector for secure attachment in demanding environments.
• Cable Specifications: 75 Ω coaxial FEP insulated probe cable with 0.5 meter total length provides signal integrity and chemical resistance.
• Armor Protection: Stainless steel armor protects the cable assembly in harsh industrial installations.

Frequently Asked Questions

• What does the 90mm unthreaded length option mean for this Bently Nevada 330904?
  The -09 option provides 90mm of unthreaded length before the M8x1 threads begin, allowing deeper insertion or specialized mounting configurations with 3300 NSv Probes.
• What target size does this proximity probe require?
  For optimal performance, use a flat target with recommended minimum diameter of 13 mm (0.5 in). Minimum acceptable diameter is 8.9 mm for the 3300 NSv Probe.
• Is this probe compatible with existing Bently Nevada systems?
  Yes, the 3300 NSv probe is mechanically and electrically compatible with previous 3300 RAM proximity probe systems and extension cables.
