330909-00-60-10-01-CN Bently Nevada 3300 NSv Proximity Probe

Bently Nevada 3300 NSv Proximity Probe 330909-00-60-10-01-CN – High-Performance Vibration Monitoring

• Model & configuration: 330909 features a 3/8‑24 UNF threaded case with stainless steel armor. The 1.0 meter total length (39 inches) includes a miniature coaxial ClickLoc connector with protector for secure field wiring.

• Linear measurement range: 1.5 mm (60 mils) starting 0.25 mm from target, with recommended static gap of 1.0 mm (40 mils) for optimal performance.

• Sensitivity & accuracy: Incremental scale factor 7.87 V/mm (200 mV/mil) ±12.5%/-20% including interchangeability error. Deviation from straight line is less than ±0.06 mm (±2.3 mils).

• Frequency response & wiring: 0 to 10 kHz ±3 dB typical with up to 305 m (1000 ft) of field wiring. Use three‑conductor shielded triad cable, 16‑24 AWG.

• Environmental tolerance: Operating temperature -52°C to +177°C (-62°F to +351°F). Probe case is AISI 304 stainless steel, tip material polyphenylene sulfide (PPS).

• Mechanical limits: Maximum installation torque 0.56 N•m (5 in‑lb); connector‑to‑connector torque 11.3 N•m (100 in‑lb) recommended. Minimum bend radius 25.4 mm (1.0 in).

• Target & mounting: Recommended flat target diameter ≥13 mm (0.5 in). Probe seals differential pressure via Viton O‑ring (custom pressure testing available on request).

• Electrical characteristics: Probe dc resistance (1.0 m length) 4.2 ±0.5 Ω from center to outer conductor. Extension cable capacitance 69.9 pF/m typical.

• What the package contains: One 330909 probe with armor, factory‑installed miniature ClickLoc connector and cable protector. Documentation includes original Bently Nevada data sheet references.

• Shipping & logistics: We dispatch within 5 working days via FedEx, UPS, or DHL. All orders are new, original stock, and we accept 30‑day returns.

Frequently Asked Questions – 330909 Proximity Probe

• Is the 330909 interchangeable with older 3300 RAM probes? Yes, it is mechanically and electrically compatible with previous 3300 RAM probes and extension cables, offering enhanced chemical resistance.

• What is the recommended gap setting for this probe? Set the initial gap to 1.0 mm (40 mils) to operate within the linear range of 0.25‑1.75 mm from target.

• Can I use this probe on a shaft smaller than 13 mm? For diameters below 13 mm, expect a scale factor change. Reducing the probe‑to‑target gap minimizes this effect – refer to Figure 12 in the manual.

• What type of extension cable works with the 330909? Use the 3300 XL NSv Proximitor Sensor with three‑conductor shielded triad cable up to 305 m. The miniature ClickLoc connector ensures a reliable connection.

• What is the delivery time and shipping method? We keep this model in stock. Orders ship within 5 days via FedEx, UPS, or DHL, tracking provided.

• Does the probe require pressure testing before use? Standard units are not pressure tested. Contact our custom design department if your application demands a validated pressure seal.

• What is the maximum torque I can apply to the probe case? Maximum rated torque for the 3/8‑24 threads is 22.6 N•m (200 in‑lb); recommended installation torque is 7.5 N•m (66 in‑lb).

• Are there any agency approvals for this version? The -CN option denotes country‑specific certifications. Please verify with local Bently Nevada representatives for exact compliance.
