Bently Nevada 3300 NSv Probe 330903‑00‑05‑70‑12‑05

Model configuration details

• Core model: 330903 — 3300 NSv Probe with M8x1 thread, no armor.
• Unthreaded length: -00 (00 mm) for consistent tip exposure.
• Case length: -05 (50 mm overall) for standard mounting flexibility.
• Total length: 70 (7.0 meters / 23.0 feet) for remote installation.
• Connector/cable: 12 — Miniature coaxial ClickLoc with FluidLoc cable (oil‑resistant).
• Certifications: 05 (Multi‑agency approvals including ATEX, IECEx, CSA).

Electrical characteristics

• Probe DC resistance: 5.9 ± 0.9 ohms at 7.0m total length.
• Extension cable center conductor: 0.220 Ω/m (0.067 Ω/ft).
• Extension cable shield: 0.066 Ω/m (0.020 Ω/ft).
• Extension cable capacitance: 69.9 ± 1.8 pF/m (21.3 ± 0.5 pF/ft at 25°C).
• These values ensure signal integrity over long wiring runs.

Performance metrics

• Linear range: 1.5 mm (60 mils) from 0.25 mm (10 mils) to 1.75 mm (70 mils).
• Scale factor: 7.87 V/mm (200 mV/mil) with ±12.5%/-20% tolerance.
• Frequency response: 0‑10 kHz (-3 dB max) with up to 305m (1,000ft) field wiring.
• Recommended gap: 1.0 mm (40 mils) for optimal bias voltage.
• DSL accuracy: ±0.06 mm (±2.3 mils) for precise displacement readings.

Environmental ratings

• Operating temperature: -52°C to +177°C (-62°F to +351°F) for extreme conditions.
• Storage temperature: Same wide range for safe inventory.
• Pressure seal: Viton O‑rings resist differential pressure.
• Minimum bend radius: 25.4 mm (1.0 in) to prevent cable damage.
• Probe materials: Stainless steel AISI 304 case with PPS tip.

Frequently asked questions (FAQ)

• What multi‑agency approvals does this probe have?
  The -05 certification includes ATEX, IECEx, and CSA approvals for hazardous locations. You can use it in Zone 1 and Zone 2 areas globally.
• What is the total resistance of the 7.0m probe?
  Probe DC resistance measures 5.9 ± 0.9 ohms. Add extension cable resistance (0.220 Ω/m center, 0.066 Ω/m shield) for total loop resistance.
• Can I use this probe with a 5‑meter extension cable?
  Yes, the 3300 NSv system supports extension cables up to 305 meters. Ensure total resistance stays within monitor specifications.
• What is the benefit of FluidLoc cable?
  FluidLoc resists oil and moisture ingress, protecting the coaxial conductor in lubricated environments. It extends cable life in machinery applications.
• Is the probe tip field‑replaceable?
  No, the tip is permanently sealed. The PPS material offers excellent wear resistance. Replace the entire probe if damaged.
• What is your return policy?
  We accept returns within 30 days for unused items in original packaging. Return shipping is the buyer's responsibility.
• How does temperature affect scale factor?
  The scale factor tolerance (±12.5%/-20%) includes temperature effects over the -52°C to +177°C range. Calibration compensates for most applications.
