Bently Nevada 330104‑01‑05‑50‑02‑02 – Comprehensive Product Overview

1. Product Overview

The Bently Nevada 330104‑01‑05‑50‑02‑02 is a high‑precision eddy current proximity probe designed for non‑contact measurement of shaft vibration, radial position, and displacement in rotating machinery.

This model is part of the 3300 XL Proximity Probe Series, a widely used industrial sensing solution for machinery condition monitoring, vibration diagnostics, and protection systems. The probe combines a medium‑length probe case with a 2‑meter system cable, making it suitable for applications where the monitoring electronics are located some distance from the sensing point while still maintaining a compact overall installation footprint.

The “02‑02” suffix indicates specific configuration options related to connector type and internal assembly tailored for standardized industrial control systems.

5. Product Description

The 330104‑01‑05‑50‑02‑02 is engineered for precise and continuous monitoring of machinery vibration and shaft displacement without mechanical contact. Utilizing eddy current sensing principles, the probe generates a voltage signal proportional to the distance between the probe tip and the surface of a conductive shaft. Because there is no physical contact, wear and drift are significantly minimized, enabling long service life and stable performance.

The medium‑length case facilitates installation in machine housings with typical clearance requirements, while the 2‑meter system cable allows for greater flexibility in placing the proximity electronics relative to the measurement location. Its standardized threaded mounting and miniature coaxial connector offer straightforward installation and serviceability.

Constructed from stainless steel with an oil‑resistant cable jacket and IP67 environmental protection, the probe withstands dust, moisture, oil contamination, and vibration commonly found in industrial environments.

6. Applications

The 330104‑01‑05‑50‑02‑02 proximity probe is suitable for a wide range of rotating machinery and monitoring applications, including:

• Steam turbine radial vibration measurement
• Gas turbine rotor position tracking
• Centrifugal and reciprocating compressor vibration diagnostics
• Industrial pump vibration and displacement monitoring
• Electric motor shaft health monitoring
• Gearbox radial displacement sensing

Common system functions:

• Radial shaft vibration amplitude measurement
• Axial displacement and position tracking
• Phase and speed reference (keyphasor) generation
• Integration into predictive maintenance systems
• Protection trip systems in critical machinery

The 2‑meter cable facilitates routing to local panels, monitoring racks, or distributed control systems.
