The Bently Nevada 330901-00-09-10-02-05 is an intrinsically safe 3300 NSv Proximity Probe designed for small shaft vibration and position monitoring. Featuring a 1/4-28 UNF thread and ClickLoc connector, it provides high-precision displacement sensing in confined industrial spaces where standard sensors are unsuitable
The Bently Nevada 330901-00-09-10-02-05 functions as a specialized eddy current sensor within the 3300 NSv (Non-Standard vent) Proximity Transducer System. This probe measures static and dynamic distances between the probe tip and a conductive target, typically a rotating shaft. Because engineers often encounter confined installation spaces or small-diameter shafts, this “NSv” variant utilizes a tighter magnetic field to prevent interference from surrounding metal, ensuring accurate vibration and position data in restricted areas.
Furthermore, this specific configuration features a 1/4-28 UNF thread and an unthreaded length optimized for precise gapping. The probe utilizes a high-quality polyphenylene sulfide (PPS) tip, which withstands the harsh oils and high temperatures common in industrial machinery housings. Since the system converts mechanical movement into a proportional voltage signal, it allows the 3500 Monitoring System to detect early signs of bearing wear, shaft misalignment, or rotor instability. Its robust construction ensures long-term reliability for critical assets where standard proximity sensors cannot be physically accommodated.
Reliability teams implement the 330901 NSv probe in specialized machinery monitoring environments. Specifically, the probe delivers critical data for:
