Core Features & Advantages

• NSv Geometry for Space-Constrained Installations: The module’s standout feature is its Narrow Side View (NSv) design, which features a narrower side view of the magnetic field compared to standard 8 mm probes. This significantly reduces counter-bore requirements and minimizes “cross-talk” in high-density mounting scenarios, enabling reliable vibration measurement where standard probes would fail due to side-wall interference .

• Armored Cable for Mechanical Protection: The 330909 base model includes stainless steel armor over the probe cable, providing enhanced mechanical protection against abrasion, crushing, and accidental impact. This is critical in high-vibration environments such as compressor skids and reciprocating machinery, where standard cables would be vulnerable to damage .

• Chemical Resistance and Pressure Sealing: The probe features a PPS (Polyphenylene Sulfide) tip that provides superior chemical resistance, and a Viton® O-ring that acts as an effective process pressure barrier. This makes the probe suitable for applications exposed to oils, process gases, and other harsh fluids .

• Complete Interchangeability with Legacy Systems: The 3300 NSv probe is mechanically and electrically interchangeable with legacy 3300 RAM systems, making it a direct replacement for existing installations without requiring system reconfiguration .

Typical Applications

The 330909-00-25-10-02-00 is widely used for critical rotating machinery monitoring in space-constrained installations :

• Centrifugal Air Compressors: Radial vibration monitoring where tight clearance around bearing housings prevents standard probe installation

• Refrigeration Compressors: Axial position measurement with restricted counter-bore access

• Process Gas Compressors: Shaft vibration monitoring on small shafts (under 51 mm diameter)

• Reciprocating Machinery: Vibration and position monitoring in high-vibration environments benefiting from armored cable protection

Frequently Asked Questions (FAQ)

Q1: What does the model number “330909-00-25-10-02-00” indicate?
A: The breakdown is: 330909 = 3300 NSv armored probe with 3/8-24 UNF thread; -00 = 0.0 in unthreaded length; -25 = 2.5 in case length; -10 = 1.0 meter cable; -02 = Miniature ClickLoc™ connector with standard cable; -00 = No agency approvals .

Q2: What is the main advantage of the NSv probe over standard 8 mm probes?
A: The NSv probe offers greater chemical resistance and better side-view characteristics than previous generations. Its narrower magnetic field reduces counter-bore requirements and minimizes cross-talk in high-density mounting scenarios, making it ideal for tight installations .

Q3: Can this probe be used with legacy 3300 RAM systems?
A: Yes. It is mechanically and electrically interchangeable with legacy 3300 RAM probes and cables, allowing direct replacement in existing installations .

Q4: What is the recommended gap setting for this probe?
A: The recommended gap setting is 1.0 mm (40 mils). The linear range spans from 0.25 mm to 1.75 mm .

Q5: What is the significance of the Viton® O-ring?
A: The Viton® O-ring acts as a pressure differential seal, preventing process fluids or gases from leaking through the probe mounting point. This is critical in high-pressure compressor applications .

Q6: What is the maximum operating temperature?
A: The probe operates from -52°C to +177°C (-62°F to +351°F). Avoid sustained exposure below -34°C to prevent seal damage .

Q7: Does this probe require agency approvals for hazardous areas?
A: This specific model (-00 suffix) has no agency approvals and is suitable for general-purpose environments only. For hazardous area installations, select a variant with the appropriate approval suffix (e.g., -05 for ATEX/IECEx) .

Q8: What are the installation torque specifications?
A: Recommended torque is 11.3 N·m (100 in·lb) for connector-to-connector, and 7.5 N·m (66 in·lb) for probe case to connector. Maximum thread engagement is 0.563 inches .

Q9: Can this probe be used with non-Bently Nevada monitoring systems?
A: While technically compatible with any monitoring system using 75Ω probes, Bently Nevada strongly recommends using it only with calibrated Bently Nevada 3300 XL NSv Proximitor sensors to ensure signal accuracy and system-level compliance .
