Bently Nevada 3300 NSv Compact Proximity Probe

The Bently Nevada 3300 NSv proximity probe is a versatile sensor for tight-space applications. This model 330903-00-11-05-02-CN features a compact M8x1 metric thread and a short 0.5-meter cable. It offers enhanced chemical resistance for challenging environments like process compressors. The probe provides reliable vibration and position data with excellent side-view characteristics. This 3300 NSv model is a direct, improved replacement for older 3300 RAM probes.

• Linear Range: Provides a 1.5 mm (60 mil) linear measurement range.
• Recommended Gap: Optimal gap setting is 1.0 mm (40 mils) from the target.
• Sensitivity (ISF): 7.87 V/mm (200 mV/mil) +12.5%/-20% including interchangeability.
• Linearity (DSL): Deviation is less than ±0.06 mm (±2.3 mils).
• Frequency Response: 0 to 10 kHz: +0, -3 dB typical with long field wiring.

Mechanical Design & Compatibility

• Thread Type: Compact M8 x 1.0 metric mounting thread.
• Max Thread Engagement: Do not exceed 12 mm of thread engagement.
• Installation Torque: Recommended torque is 5.1 N•m (45 in•lb); maximum is 7.3 N•m.
• Case Material: Manufactured from AISI 304 stainless steel.
• Tip Material: Probe tip is made of chemical-resistant Polyphenylene sulfide (PPS).
• Backward Compatibility: Mechanically and electrically interchangeable with older 3300 RAM probes.

Cable & Electrical Data

• Cable Type: 75 Ω coaxial cable with FEP insulation.
• Cable Capacitance: Extension cable typical is 69.9 pF/m (21.3 pF/ft).
• Cable Resistance: Center conductor: 0.220 Ω/m; Shield: 0.066 Ω/m.
• Minimum Bend Radius: 25.4 mm (1.0 inch) with or without armor.
• Field Wiring: Use 3-conductor shielded triad cable (16-24 AWG). Max length 305m to monitor.

Application & Installation Notes

• Target Size: Minimum target diameter is 8.9 mm (0.35 in); recommended is 13 mm (0.5 in).
• Chemical Resistance: Enhanced design allows use in many process compressor applications.
• Side-View Performance: Offers superior characteristics compared to older 3000-series 190 probes.
• Axial Measurement: On small shafts, reduce the gap to minimize scale factor changes.
• Short Cable Use: The 0.5m length is ideal for applications where the sensor is mounted very close to the entry point.

Frequently Asked Questions (FAQ)

Is this probe a direct replacement for a 3300 RAM probe?

• Yes. The 3300 NSv probe is mechanically and electrically interchangeable with the older 3300 RAM probe. It also offers improved chemical resistance, making it a superior drop-in replacement.

What does "Country Specific (CN)" mean for approvals?

• This indicates the probe is supplied with documentation or markings required for import and use in specific countries. It may relate to local compliance certificates or labeling standards beyond the base international approvals.

Why is the M8x1 thread size beneficial?

• The M8x1 thread is a small metric standard. It is perfect for applications with limited space for sensor mounting, often found in compact machinery or European-designed equipment.

What is the minimum target size for accurate measurement?

• The absolute minimum is a 8.9 mm (0.35 in) diameter flat target. For best and most consistent results, use a target of at least 13 mm (0.5 in) in diameter.

How do I handle the very low installation torque?

• The recommended torque is only 5.1 N•m (45 in•lb). Use a calibrated torque wrench to avoid overtightening and damaging the small M8 threads. "Finger tight" is a good initial step.
