Bently Nevada 3300 NSv Probe 330903‑00‑03‑70‑12‑00

Brand and model configuration

• Brand: Bently Nevada — industry leader in condition monitoring.
• Model: 3300 NSv Proximity Probe with part number 330903‑00‑03‑70‑12‑00.
• Unthreaded length: 00 mm (protrusion for consistent gap).
• Overall case length: 30 mm (compact for tight installations).
• Total probe length: 7.0 meters (flexible routing to junction boxes).
• Connector type: Miniature coaxial ClickLoc with FluidLoc cable (oil‑resistant).
• Agency approval: 00 (standard version without special certifications).

Critical performance specifications

• Measuring range: 0.25 mm to 1.75 mm (10–70 mils) for wide coverage.
• Linear range: 1.5 mm (60 mils) ensures consistent output.
• Recommended gap: 1.0 mm (40 mils) for optimal bias voltage.
• Scale factor (ISF): 7.87 V/mm (200 mV/mil) with ±12.5% / -20% tolerance.
• DSL accuracy: ±0.06 mm (±2.3 mils) for precise displacement readings.
• Probe resistance: 5.9 ± 0.9 Ω at 7.0 m length (includes cable).
• Frequency response: 0–10 kHz, ±3 dB typical for dynamic events.
• Signal output: Voltage proportional to gap, compatible with 3300 monitors.

Environmental and mechanical durability

• Operating temperature: -52°C to +177°C (-62°F to +351°F) for extreme conditions.
• Storage temperature: Same wide range for safe stock keeping.
• Pressure seal: Viton O‑rings resist differential pressure (not pressure‑tested).
• Minimum bend radius: 25.4 mm (1.0 in) to prevent cable damage.
• Probe materials: Stainless steel case with PPS tip for corrosion resistance.

Frequently asked questions (FAQ)

• What is the linear range of model 330903‑00‑03‑70‑12‑00?
  The linear range covers 0.25 mm to 1.75 mm (1.5 mm span). This matches standard proximity probe requirements for most machinery.
• Can I use this probe with a 5‑meter extension cable?
  Yes, the 3300 NSv system works with extension cables up to 305 meters. The total resistance includes probe plus extension, so verify compatibility with your monitor.
• What does FluidLoc cable mean?
  FluidLoc is a Bently Nevada design that resists oil and moisture ingress. It protects the coaxial conductor in lubricated environments.
• Is the probe tip field‑replaceable?
  No, the tip is permanently sealed. If damaged, you must replace the entire probe assembly. The PPS material offers high wear resistance.
• What is the return policy?
  You can return unused items within 30 days. Return shipping costs are the buyer's responsibility. We must receive the probe in original packaging.
• How do I install the Viton O‑ring correctly?
  Place the O‑ring in the groove near the mounting threads. It seals the housing against oil ingress but does not provide full pressure testing.
