Bently Nevada 330130-045-00-05 Proximity Probe 8mm

Technical Overview

The Bently Nevada 330130-045-00-05 is a high-precision 8mm proximity probe engineered for non-contacting vibration and displacement measurement in hazardous industrial environments. By translating the gap between the probe tip and a conductive shaft into a proportional voltage signal, it provides critical data for the 3300 XL monitoring system, ensuring the mechanical health of high-speed turbines, compressors, and pumps.

Typical Applications

This extended-reach, certified probe is designed for complex installations where safety and physical depth are paramount:

• Hazardous Area Monitoring: Certified for use in explosive atmospheres (Zone 0, 1, and 2) common in oil and gas refineries.

• Through-Casing Measurement: The 4.5-inch unthreaded length allows the probe to reach the shaft through thick machine insulation or deep mounting bores.

• Radial Vibration Analysis: Continuous monitoring of shaft-to-bearing clearance in large-scale centrifugal compressors.

• Axial Position Tracking: Measuring rotor movement in steam turbines to prevent thrust bearing failure.
