The Bently Nevada 330173-00-03-10-02-CN is a 3300 XL NSV metric proximity probe featuring a 30mm case and 1.0m cable. It provides precision small-shaft monitoring with CN-specific certification.
The Bently Nevada 330173-00-03-10-02-CN functions as a high-precision, non-contacting sensor designed for the 3300 XL NSV (Near Proximity) Transducer System. This specific probe utilizes a 3/8-24 UNF threaded body and serves the primary function of measuring shaft vibration in extremely confined spaces. By generating a high-frequency eddy current field, the sensor detects the microscopic gap between the probe tip and a target metal surface. The NSV system excels in monitoring small-diameter shafts or targets with limited clearances that would otherwise interfere with standard 8mm probe signals.
Engineers designed this configuration with an M10 x 1 threaded body and a 1.0-meter integral cable. This model features a 30mm overall case length with no unthreaded portion, providing a compact footprint for restrictive mounting locations. Furthermore, the “CN” designation confirms that the hardware complies with Chinese regional standards, ensuring the sensor meets all necessary regulatory requirements for local industrial deployment. The 3300 XL NSV series also incorporates advanced temperature compensation to maintain an accurate scale factor despite the thermal fluctuations common in high-speed machinery operation.
This proximity probe actively facilitates predictive maintenance by delivering real-time machinery health data to the 3500 Monitoring System. Because the NSV system accurately tracks targets as small as 13mm in diameter, it provides critical protection for auxiliary machinery that standard sensors cannot accommodate. Consequently, plant operators can detect early indicators of mechanical distress like rotor imbalance or bearing wear, which helps prevent catastrophic asset failure and extends the lifespan of expensive equipment.
Primary industrial applications include:
Bently Nevada utilizes 304 stainless steel and PPS (polyphenylene sulfide) resin to ensure long-term survival in aggressive plant atmospheres. This robust construction creates a hermetic seal that resists the ingress of moisture, lubricating oils, and process steam. Additionally, the patented ClickLoc connector technology provides a secure, vibration-resistant electrical path. This locking mechanism prevents signal attenuation often caused by mechanical oscillations, ensuring that the Proximitor sensor receives a clean signal for precise machinery diagnostic analysis.
