Brief Product Description

Bently Nevada 330106-05-30-10-02-00 is a 3300 XL 8mm eddy current proximity probe for rotating machinery monitoring. This probe comes with 5-meter integral cable, 30mm unthreaded tip length and 3/8-24 mounting thread. It forms a complete transducer system together with matched extension cable and Bently 3500 monitor module. Using eddy current non-contact measurement principle, it detects radial shaft vibration, axial thrust displacement and shaft position of turbines, compressors and other rotating equipment. The stainless steel sealed probe body is designed to withstand high temperature, oil mist and continuous mechanical vibration in heavy industrial environments. Fully tested surplus and refurbished Bently 330106-05-30-10-02-00 probes are available for legacy machinery monitoring system maintenance, probe replacement and plant equipment retrofit projects.

Core Product Functions

• 8mm eddy current proximity sensor for non-contact gap, vibration and displacement measurement
• Real-time monitoring of rotating shaft radial vibration, axial thrust position and rotor eccentricity
• Eddy current sensing principle for conductive metal target surface measurement
• Pair with matched extension cable and 3500 monitor to convert gap value into analog voltage signal

FAQ (Frequently Asked Questions)

• Q: Unstable vibration readings or signal loss after installing 330106-05-30-10-02-00?
  A: Check probe installation gap, inspect cable and connector integrity, verify target material and surface finish, check shielding grounding and confirm 3500 monitor configuration.
• Q: Does Bently 330106-05-30-10-02-00 support hot-swap replacement?
  A: Hot swap is not permitted. Shut down rotating equipment and perform lockout-tagout before replacement to avoid mechanical damage and safety hazards.
• Q: What series does 330106-05-30-10-02-00 belong to?
  A: It belongs to Bently Nevada 3300XL 8mm eddy current proximity probe series.
• Q: What are the main differences compared with 330103 series probes?
  A: The 330106 series has longer unthreaded tip length and longer integral cable, suitable for deeper installation space on bearing housings.
• Q: Is Bently 330106-05-30-10-02-00 available for new monitoring projects?
  A: This legacy 3300XL proximity probe is end-of-life for new installations. Only fully tested surplus and refurbished units are supplied for existing machinery monitoring system maintenance and retrofits.
