Bently Nevada 330101-00-32-05-01-05 3300 XL 8 mm Proximity Probes

Item Overview

This module 330101-00-32-05-01-05 is a 3300 XL 8 mm Proximity Probe from Bently Nevada. It features a 3/8-24 UNF thread and is supplied without armor. The 3-meter total length option is only available on 330101 probes and is designed for use with the 9-meter Proximitor sensor only. However, this specific model has a 0.5 meter total length, which is intended for use with a 5-meter system Proximitor sensor.

Application

 Radial shaft vibration monitoring – Measures vibration on fluid-film bearing machines such as steam turbines, gas turbines, compressors, and large pumps.

 Axial (thrust) position measurement – Monitors rotor axial displacement to detect thrust bearing wear and prevent rotor-to-stator rub.

 Shaft eccentricity measurement – Detects rotor bow during startup or shutdown of large turbines.

 Differential expansion monitoring – Measures relative thermal growth between rotor and stator in steam turbines and compressors.

 Bearing wear detection – Enables early identification of bearing degradation and shaft misalignment.

 Condition monitoring of critical assets – Integrates into API 670 compliant machinery protection systems for predictive maintenance.

 0.5 meter total length – Ideal for compact installations where the Proximitor sensor is mounted close to the measurement point.

 3/8-24 UNF thread – Standard imperial thread for North American machine casings.
