Description

Bently Nevada 330173-08-18-10-02-00 3300 XL 5mm Proximity Probe

The Bently Nevada 330173-08-18-10-02-00 is a high-precision non-contacting transducer designed for industrial displacement and vibration sensing. As a specialized 5mm probe within the 3300 series, it is engineered for applications with restricted installation space where a standard 8mm probe cannot be utilized. This sensor measures the gap between the probe tip and a conductive target, converting the physical distance into a proportional voltage signal used by monitoring systems to assess shaft radial vibration, axial position, and eccentricity.

Technical Performance and Environmental Resilience

The 330173 series is constructed to maintain superior signal stability under intense industrial stressors. Specifically, the 5mm tip allows for high-resolution measurements on smaller target areas without sacrificing the ruggedness required for machine internals. Furthermore, the probe is built with a high-strength cable and gold-plated ClickLoc coaxial connectors that provide a moisture-resistant and vibration-proof interface. Consequently, the system remains immune to the effects of electromagnetic interference (EMI) and can operate reliably in temperatures ranging from -51 °C to +177 °C. This ensures that the diagnostic data used for machinery protection is both consistent and accurate.

Critical Machinery Monitoring and Reliability

Deploying the 330173-08-18-10-02-00 probe is a vital step in modern predictive maintenance programs. As a result, operators can identify early indicators of mechanical distress, such as bearing degradation or shaft misalignment, before they escalate into catastrophic failures. Moreover, the inclusion of the factory-installed connector protector ensures the signal path is shielded from oil and environmental contaminants during long-term operation. Therefore, this transducer is an essential component for protecting high-speed rotating equipment in the oil and gas, power generation, and chemical processing industries. Ultimately, the precision of this 5mm system enhances overall plant safety and reduces the frequency of unplanned outages.

FAQ

When should I use a 5mm probe instead of the standard 8mm version?

The 5mm probe is typically selected when the physical mounting space is too small for a 3/8-24 thread or when the target surface (shaft diameter) is extremely narrow. Specifically, it provides a smaller footprint while maintaining the high performance of the 3300 XL series. Accordingly, always ensure your Proximitor sensor is calibrated specifically for the 5mm probe type.

What does the “02” option represent in the model string?

The “02” suffix confirms that this probe is equipped with a connector protector. In addition, this protector is a transparent, heat-shrinkable sleeve that prevents fluids and particulates from entering the coaxial connection point. Consequently, it is highly recommended for probes installed inside machine housings where oil mist is present.

Is this probe compatible with standard 3300 XL extension cables?

This probe must be used with a 5mm-specific extension cable to maintain the proper system capacitance. Furthermore, the total electrical length (probe plus extension cable) must match the requirements of the Proximitor—typically 5.0 or 9.0 meters. Therefore, verify your system configuration before completing the installation to avoid calibration errors.

Can this probe withstand high-pressure environments?

Bently Nevada proximity probes are designed to be fluid-tight; however, for high-pressure applications, it is often necessary to use a specialized pressure seal or housing. Moreover, ensure that the probe tip material (PPS) is compatible with the specific chemicals or gases present in your machine. Ultimately, proper mounting is key to maintaining the integrity of the pressure boundary.
