Bently Nevada 3300 XL 8 mm Proximity Probe 330104-00-07-05-02-00

Product Overview

The Bently Nevada 330104-00-07-05-02-00 serves as a high-precision transducer within the 3300 XL 8 mm Proximity Transducer System. This eddy current sensor measures the static and dynamic distance between the probe tip and a conductive target material. Consequently, it enables industrial operators to monitor vibration, axial position, and speed in critical rotating machinery. By providing real-time displacement data, this probe allows maintenance teams to identify mechanical irregularities before they lead to catastrophic equipment failure.

Industrial Applications and Functional Benefits

Industrial facilities utilize these probes primarily in Turbine Supervisory Instrumentation (TSI) systems to safeguard high-speed assets. Furthermore, because the probe features a robust polyphenylene sulfide (PPS) tip, it maintains structural integrity even when exposed to corrosive lubricants or high-temperature environments.

Specifically, the 330104 series excels in monitoring the following:

• Radial vibration in fluid-film bearing machines
• Thrust position measurements in steam and gas turbines
• Shaft eccentricity and differential expansion
• Phase reference and speed sensing (Keyphasor) applications

Furthermore, the 3300 XL system offers a significant improvement in moisture resistance compared to previous generations. This ensures that the sensor maintains signal stability in humid or oil-mist environments, which directly enhances the accuracy of the diagnostic data sent to the monitoring rack.

Operational Integration

The probe interfaces directly with a 3300 XL Extension Cable and Proximitor Sensor. Together, these components create a calibrated system that converts the mechanical gap into a proportional voltage signal. Because the system follows a standard 7.87 V/mm (200 mV/mil) scale factor, it integrates seamlessly with Bently Nevada 3500 series monitoring racks and various Distributed Control Systems (DCS). Consequently, plant managers gain a reliable stream of data to support predictive maintenance strategies and optimize asset longevity.
