Technical Specifications Matrix
| Manufacturer / Brand | Bently Nevada (GE) |
| Model & Series | 330908-12-36-70-02-05 / 3300 NSv Series (330908) |
| Probe Tip & Case Material | Polyphenylene sulfide (PPS) tip with AISI304 stainless steel (SST) case |
| DC Resistance (R_PROBE) | 5.9 ± 0.9 ohms measured from center conductor to outer conductor |
| Operating & Storage Range | -52 degrees Celsius to +177 degrees Celsius (-62°F to +351°F) |
| Mechanical Torques | 11.3 N•m (100 in•lb) recommended; 33.9 N•m (300 in•lb) maximum limit for 3/8-24 cases |
| Thread Engagement Limits | Maximum length of thread engagement restricted to 0.563 inches |
| Pressure Sealing | Viton O-ring design sealing differential pressures between probe tip and case |
| Physical Weight | Approximately 14 to 150 grams (0.5 to 5.3 oz) based on build variants |
Installation and Mechanical Guidelines
- Verify that thread engagement does not exceed the 0.563-inch maximum limit during panel or machine casing insertion.
- Apply the recommended 11.3 N•m (100 in•lb) torque using a calibrated wrench to prevent thread galling on the stainless steel housing.
- Avoid exposing the probe tip to sustained temperatures below -34°C (-30°F) prior to installation to protect the Viton O-ring pressure seal.
- Route the 75-ohm fluoroethylene propylene (FEP) coaxial cable away from high-voltage power conduits to minimize electromagnetic interference.
Global PLC Spare HUB's Insight
Field maintenance engineers often face monitoring challenges on small high-speed compressors, centrifugal refrigeration units, or specialized turbines where standard 8mm proximity probes lack spatial clearance. Deploying the 330908-12-36-70-02-05 solves these constraints by providing linear vibration tracking on restricted target areas. For instance, during a high-speed turbocharger retrofit, replacing standard probes with the 330908 series eliminated erratic runout waveforms caused by edge-effect distortion on sub-50mm shafts.
Typical Equipment and Application Scenarios
- Radial vibration and axial thrust position tracking on small-diameter industrial gearboxes.
- Slow-roll shaft eccentricity monitoring on specialized steam turbines.
- Process gas and centrifugal air compressors with severe counterbore spatial restrictions.
- Laboratory test stands evaluating micro-tolerance rotor dynamics.
Global Logistics, Warranty, and Compliance
- Fulfillment & Shipping: Expedited global dispatch within 24-48 hours via trusted couriers including FedEx, UPS, and DHL.
- Warranty Protection: Covered by a comprehensive 12-month operational replacement warranty.
- Regulatory Standards: Built with multiple hazardous area agency certifications (Option 05).
Technical Model Selection and Comparison
| Comparison Model Link | Key Differences & Engineering Application Notes |
| 330908-22-31-10-01-05 | Features a shorter 1.0-meter total system length and different unthreaded/case length options (Options 22 and 31), making it ideal for compact local junction box configurations rather than long-run cable drops. |
Frequently Asked Questions
What physical restriction makes the 330908-12-36-70-02-05 necessary over standard 3300 XL probes?
The NSv probe uses a specialized smaller tip design specifically calibrated for targets smaller than 15mm or shafts under 51mm where standard linear fields overflow.
How can technicians verify probe health using electrical resistance checks?
Measure the DC resistance between the center conductor and outer shield; a reading aligning with the nominal 5.9 ± 0.9 ohms confirms internal coil integrity.
What safety precaution applies to sub-zero storage handling?
Do not expose the probe assembly to sustained temperatures below -34°C prior to mounting, as extreme cold hardens the Viton O-ring seal and causes premature failure.
Why is the ClickLoc connector preferred in high-vibration machinery?
The ClickLoc miniature coaxial mechanism locks securely into place, preventing micro-motion disconnection caused by continuous mechanical oscillation.
