The Bently Nevada 330103-00-04-15-02-CN is a 3300 XL 8mm proximity probe designed for non-contact vibration and position monitoring. Featuring an M10x1 threaded case, a 1.5-meter cable, and hazardous area certification (-CN), this eddy current sensor provides high-precision data for turbomachinery protection and early fault detection in harsh industrial environments.
The Bently Nevada 330103-00-04-15-02-CN functions as a high-precision eddy current proximity sensor within the industry-standard 3300 XL 8mm transducer system. This probe accurately measures the distance between the probe tip and a rotating shaft, enabling the non-contacting measurement of both static (position) and dynamic (vibration) parameters. By converting these physical displacements into electrical signals, the module provides critical data for monitoring radial vibration, axial thrust position, and eccentricity in high-speed turbomachinery.
Furthermore, the 3300 XL system incorporates significant design improvements over previous generations. The probe utilizes a specialized “ClickLoc” connector that resists environmental contamination while maintaining a secure electrical bond. Consequently, the sensor delivers a linear output across a wide range, even in the presence of industrial lubricants and high-temperature gradients. This reliability makes the 330103 model a cornerstone for machine protection in power plants, refineries, and petrochemical facilities.
In addition to its measurement accuracy, this specific configuration includes the “-CN” designation, indicating compliance with regional Chinese certification standards for hazardous area installations. The probe’s 8mm tip diameter balances sensitivity and range, providing a standard scale factor of 7.87 V/mm (200 mV/mil) when used with a compatible 3300 XL Proximitor Sensor. By implementing this proximity probe, plant operators can detect early-stage mechanical faults—such as shaft misalignment or bearing wear—long before they escalate into catastrophic equipment failure.
The Bently Nevada 31000-16-10-15-030-03-02 is a specialized proximity probe housing designed to physically protect a proximity probe and its integral cable within harsh industrial environments. Its primary function is to provide a secure, environmentally sealed mounting point on rotating machinery for acquiring critical vibration and position data. The housing is constructed from 304 Stainless Steel, offering robust protection against physical impact and corrosion. This specific configuration, 31000-16-10-15-030-03-02, features a 3/4-14 NPT external mounting thread for direct installation into a machine case. Internally, it accommodates a Bently Nevada 3300 XL 8 mm or 3300 5 mm probe, which is positioned by a 1.0-inch stinger (probe sleeve). The housing facilitates the signal path from the probe tip to the Bently Nevada 3500 Monitoring System. The probe, connected via an extension cable to a Proximitor Sensor, generates a high-frequency RF signal. The resulting eddy current field is used to measure the distance to the observed conductive target. The Proximitor Sensor conditions this signal into a calibrated DC voltage proportional to the gap, which is then transmitted to a 3500/42M Proximitor/Seismic Monitor module for analysis, alarming, and machinery protection.

In Oil & Gas applications, the 31000-16-10-15-030-03-02 housing provides essential protection for transducers monitoring centrifugal and reciprocating compressors, pumps, and gearboxes. Its 304 Stainless Steel construction and Viton seals ensure long-term integrity in environments containing corrosive elements such as H2S and hydrocarbons, a critical requirement for meeting API 670 standards for machinery protection systems. In Power Generation, this housing is extensively used on steam and gas turbines, exciters, and boiler feed pumps. It maintains measurement accuracy and reliability under conditions of high temperature and vibration, which is fundamental for monitoring shaft radial vibration, axial thrust position, and differential expansion. The passive mechanical design results in a high Mean Time Between Failures (MTBF), contributing to overall plant availability. When properly installed, the housing assembly provides an environmental rating equivalent to NEMA 4X and IP65, preventing ingress of dust, moisture, and process contaminants that could otherwise compromise signal integrity
The Bently Nevada 330104-00-14-10-11-00 Proximity Probes is a genuine industrial component.
