Technical Specifications

• Brand & Model: Bently Nevada | 3300 NSv Proximity Probe (Part Number: 330904-00-12-05-02-00)
• Full Suffix Configuration:
  • 330904 = 3300 NSv Probe, M8x1 thread, with armor
  • -00 = 0 mm unthreaded length
  • -12 = 120 mm overall case length
  • 05 = 0.5 meter (20 in) total length
  • 02 = Miniature coaxial ClickLoc connector, standard cable
  • -00 = No agency approval required
• Measurement Range: Linear range of 1.5 mm (60 mils) from 0.25 mm to 1.75 mm target gap.
• Recommended Gap: Set at 1.0 mm (40 mils) for optimal DC voltage output.
• Sensitivity (ISF): 7.87 V/mm (200 mV/mil) with +12.5% / -20% interchangeability error.
• Linearity (DSL): Deviation from best fit straight line is less than ±0.06 mm (±2.3 mils).
• Frequency Response: 0 to 10 kHz, +0 / -3 dB typical with up to 305 m of field wiring.
• DC Resistance: Probe center to outer conductor measures 4.0 ± 0.5 ohms at 0.5 m length.
• Temperature Range: Operates from -52°C to +177°C (-62°F to +351°F).
• Environmental Tolerance: Viton O-ring seals differential pressure; PPS tip resists harsh chemicals.
• Anti-Interference: FEP insulated 75 Ω coaxial cable with optional stainless steel armor.

Frequently Asked Questions

• Can I swap my 3300 RAM probe with this 3300 NSv Proximity Probe?
  Yes, it is mechanically and electrically interchangeable without modifying your existing extension cable or Proximitor.
• What happens if my shaft diameter is under 13 mm?
  You will see a scale factor change. Reduce the gap slightly to maintain linear performance.
• How long can my field wiring be?
  You can run up to 305 meters (1000 feet) between the Proximitor and the monitor.
• Does the probe withstand high pressure?
  Yes, the Viton O-ring seals differential pressure. Contact our custom design department if you require a pressure test certificate.
• What is the difference between 3300 NSv and 190 series side-view?
  The NSv provides superior side-view characteristics when gapping at the same target distance.
