Description

Technical Overview

The Bently Nevada 330704-00-050-10-01-05 is a rugged 11mm proximity probe engineered for high-precision displacement and vibration monitoring. As a core component of the 3300 XL Proximity Transducer System, this sensor provides a larger linear range compared to standard 8mm models, making it particularly effective for applications where a greater distance between the probe and target is required. The system generates an eddy current field to measure the gap between the probe tip and a conductive target, converting this distance into a proportional voltage signal for real-time machinery protection.

Configuration and Build Integrity

This specific model features an M14 x 1.5 metric threaded body, which ensures a secure mechanical fit in various industrial housings. The 330704-00-050-10-01-05 configuration includes:

• Case Length: 50 mm unthreaded length for versatile mounting.
• Total Length: 1.0 meter cable integrated with a miniature coaxial ClickLoc connector.
• Armor Protection: 304 stainless steel fluid-tight armor shields the cable from mechanical damage and chemical exposure.
• Environmental Sealing: The probe utilizes a polyphenylene sulfide (PPS) tip to resist oil, moisture, and chemical ingress in harsh environments.

Operational Advantages

Because Bently Nevada prioritizes system flexibility, this probe supports complete interchangeability. Consequently, users can replace probes or extension cables without the need for manual bench calibration, which significantly streamlines maintenance workflows. Furthermore, the 330704-00-050-10-01-05 adheres to the rigorous API 670 standards, guaranteeing exceptional accuracy and reliability for critical machinery monitoring. The probe also provides high resistance to Radio Frequency Interference (RFI), ensuring signal stability even in electronically noisy industrial settings.

Primary Industrial Applications

Facilities typically deploy the 3300 XL 11mm probe for monitoring large-scale rotating equipment, including:

• Radial vibration and axial thrust position in fluid-film bearing machines.
• Keyphasor signals and speed measurements.
• Shaft eccentricity and expansion monitoring in steam turbines.
• General condition monitoring for centrifugal compressors and pumps.
