Bently Nevada 330901-00-09-10-02-05 3300 NSv Proximity Probe

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

Product Description

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.
