The Bently Nevada 330171-08-24-10-02-00 is a 3300 XL NSV proximity probe with a 1.0-meter cable and a 1/4-28 UNF thread. It delivers precision vibration monitoring for small-diameter shafts and tight-clearance assets.
The Bently Nevada 330171-08-24-10-02-00 functions as a specialized, non-contacting sensor designed for the 3300 XL NSV (Near Proximity) Transducer System. This probe utilizes eddy current technology to measure shaft vibration and displacement in environments where space is restricted or where the target shaft diameter is small. By maintaining a stable linear range in tight clearances, the probe allows the monitoring system to capture high-resolution data that standard 8mm probes might miss due to “side-viewing” interference from nearby metal surfaces.
Engineers developed this NSV probe configuration with a 1/4-28 UNF threaded body to facilitate installation in compact bearing housings. This model features a 0.8-inch unthreaded section and a 2.4-inch overall case length, providing the necessary reach for specific machine geometries. Furthermore, the 330171-08-24-10-02-00 includes a 1.0-meter integral cable that connects seamlessly to the extension cable, ensuring a continuous and low-impedance signal path for high-frequency vibration data.
This proximity probe actively powers predictive maintenance strategies by delivering a reliable data stream for small-diameter rotating assets. Consequently, maintenance teams can detect subtle mechanical faults, such as rotor imbalance or bearing wear, in equipment where larger sensors are impractical. Because the NSV system excels at monitoring targets as small as 13 mm (0.5 inches), it provides a critical layer of protection for auxiliary machinery that often lacks dedicated monitoring.
Key industrial applications include:
To ensure maximum uptime, Bently Nevada utilizes a 304 stainless steel case and a PPS (polyphenylene sulfide) resin tip. This construction creates a hermetic seal that resists the ingress of moisture, oil, and steam. Additionally, the patented ClickLoc connector technology provides a secure, vibration-resistant electrical connection. This mechanism prevents signal loss caused by the high-frequency oscillations common in industrial machinery, ensuring that the Proximitor sensor receives a clean signal for precise diagnostic analysis.
