330910-00-07-05-02-00 Proximity Probe – Bently Nevada NSv

3300 NSv Proximity Probes – precision proximity transducer system

Bently Nevada 3300 NSv Proximity Probe is a side‑view, eddy‑current sensor built for harsh environments. It offers improved chemical resistance over the legacy 3300 RAM series, making it ideal for process compressors and turbines. Fully interchangeable with previous 3300 RAM probes and extension cables.

• probe tip material : polyphenylene sulfide (PPS); case : AISI 304 SST
• maximum torque on case : 33.9 N·m (300 in·lb); recommended 11.3 N·m (100 in·lb)
• minimum bend radius : 25.4 mm (1.0 in) – even with armor
• environmental sealing : Viton O‑ring seals probe tip; differential pressure rating available on request
• EMI immunity : 75 Ω coaxial construction with FEP insulation, optional armor, and twisted triad field wiring support

🔩 installation & wiring

• mounting torque : finger‑tight initially; maximum 0.56 N·m (5 in·lb) on M10x1 threads
• connector mating torque (first three threads) : max 22.6 N·m / rec. 7.5 N·m
• field wiring : 0.2 – 1.5 mm² (16‑24 AWG) three‑conductor shielded triad; max length 305 m to 3300 XL NSv Proximitor®
• ClickLoc™ connector simplifies extension cable attachment – no special tools needed

🔄 compatibility & interchangeability

• Mechanically and electrically interchangeable with previous 3300 RAM probes and extension cables
• Direct replacement for 3000‑series 190 probes in side‑view applications – superior gapping characteristics
• Works with all 3300 XL NSv Proximitor sensors; maintains calibration over wide temperature range

✅ certification & agency information

• Temperature class (probe only) for EPL Ga/Gc: T1 to T5 (–55 °C to +232 °C max depending on class)
• EPL Dc ratings available for T280°C, T225°C, T170°C, T130°C, T105°C, T90°C (ambient dependent)
• Probes are not pressure‑tested before shipment – custom pressure‑test option available through design department

🏭 typical applications & diagnostics

• Radial vibration and axial position monitoring on compressors, steam turbines, pumps, and gearboxes
• Suitable for process compressor duty due to enhanced chemical resistance of PPS tip and FEP cable
• Diagnostic capability : DC gap voltage indicates probe position; AC dynamic signal reveals vibration waveforms, rubs, and bearing faults
• Works with 3300 NSv Proximitor to provide scaled voltage (‑1 to ‑13 Vdc over linear range) for monitoring systems like 3500/40M, 3500/42M
