The Bently Nevada 330173-08-18-10-02-00 is a 3300 XL NSV proximity probe with a 1.0-meter cable and 0.8″ unthreaded length. It provides precision vibration monitoring for small-diameter shafts and tight-clearance applications.
The Bently Nevada 330173-08-18-10-02-00 operates as a high-precision, non-contacting sensor designed specifically for the 3300 XL NSV (Near Proximity) Transducer System. This probe utilizes eddy current technology to measure displacement and vibration in applications where space is extremely limited or where target shafts have small diameters. By converting the gap between the probe tip and the target into a proportional electrical signal, it allows the monitoring system to track asset health with microscopic resolution.
Engineers developed the NSV series to solve “side-viewing” issues common with standard 8mm probes when mounting in tight spaces. Consequently, this model features a compact 3/8-24 UNF threaded body that excels at monitoring shafts as small as 13 mm (0.5 inches) in diameter. Furthermore, the 3300 XL NSV series maintains a stable Scale Factor across a wide temperature range, ensuring that thermal expansion within the machinery does not result in false vibration readings.
This proximity probe actively drives predictive maintenance programs by providing a high-fidelity data stream to industrial protection systems. Because the NSV system specializes in small targets, it serves as the primary sensor for auxiliary plant equipment that larger sensors cannot accurately monitor. By identifying subtle changes in shaft orbit or position, the probe helps operators detect rotor imbalance or bearing wear before catastrophic damage occurs.
Typical industrial applications include:
To ensure survival in punishing atmospheres, Bently Nevada utilizes a 304 stainless steel case and a PPS (polyphenylene sulfide) resin tip. This construction provides a hermetic seal against oil, water, and steam ingress. Additionally, the patented ClickLoc connector technology ensures a secure, vibration-resistant electrical path. This locking mechanism prevents accidental signal loss caused by the high-frequency mechanical oscillations typical of industrial bearing housings.
The Emerson EPRO PR6423/010-000 CON021 Eddy Current Signal Converter delivers ultra-precise, non-contact displacement and vibration measurements for critical rotating machinery. Featuring an tip diameter, a rugged stainless steel housing, and advanced internal temperature compensation, it provides reliable, continuous asset protection and seamless DCS integration in harsh, high-pressure industrial environments.
