Bently Nevada 136188-02 Ethernet/RS485 Modbus I/O Module

The Bently Nevada 330104-00-08-05-02-05 is a 3300 XL 8mm proximity probe that provides precision non-contact vibration monitoring. It features a 0.5-meter cable, 1/2-20 UNF threads, and a rugged PPS tip designed for critical turbine and compressor protection in temperatures up to +177°C.

Precision Engineering for Machinery Protection

The Bently Nevada 330104-00-08-05-02-05 drives your predictive maintenance (PdM) strategy by delivering high-resolution vibration data. This 3300 XL 8mm proximity probe tracks microscopic shaft movements without physical contact, eliminating sensor wear and ensuring consistent signal accuracy. By integrating this probe into your 3500 Monitoring System, you enable early fault detection for critical rotating assets. The sensor precisely measures both radial vibration and axial thrust position, providing the raw data necessary for automated machinery protection and emergency trip logic.

Technical Performance and Robust Construction

  • Optimized Signal Integrity: The 3300 XL system minimizes signal noise and provides an industry-leading linear range of 2.0 mm (80 mils).
  • Rugged PPS Tip: The probe employs a polyphenylene sulfide (PPS) tip that resists chemical corrosion and moisture ingress in harsh industrial environments.
  • Thermal Stability: Operates reliably in temperatures ranging from -52°C to +177°C, maintaining calibration accuracy despite thermal cycling.
  • API 670 Compliance: Meets all requirements of the American Petroleum Institute Standard 670 for vibration monitoring systems.
  • ClickLoc Connector: The gold-plated ClickLoc connector ensures a secure, vibration-resistant link between the probe and extension cable.

Strategic Industry Applications

Maintenance teams deploy the 330104 series to safeguard high-capital assets across power generation and oil and gas sectors. This probe monitors:

  • Fluid-film bearing performance in steam and gas turbines
  • Axial displacement in high-pressure centrifugal compressors
  • Shaft eccentricity and thermal expansion during machine startup
  • Real-time speed and phase reference using Keyphasor technology

Installation and System Configuration

Technicians install the 330104-00-08-05-02-05 using its standard 1/2-20 UNF threads. For a complete 5.0-meter measurement loop, pair this 0.5-meter probe lead with a 4.5-meter 3300 XL extension cable. The factory-installed connector protector (02 option) seals the coaxial connection against lubricating oils and contaminants, effectively preventing ground loops. This integrated protection ensures that your condition monitoring system receives a clean, actionable data stream for advanced rotor dynamics analysis.
