Brief Product Description

330106‑05‑30‑05‑02‑05 is an 8 mm reverse‑mount eddy‑current proximity probe belonging to Bently Nevada 3300 XL sensor series. This non‑contact sensing probe features 0.5‑meter integral armored cable, Miniature ClickLoc coaxial connector and multi‑agency approvals. Working together with matching extension cable and proximitor, it delivers high‑precision measurement of shaft radial vibration, axial displacement and key‑phasor speed signal for rotating machinery. Stainless‑steel housing and PPS probe tip support wide temperature range and harsh industrial cabinet installation. Thanks to full component interchangeability, no matched‑pair calibration is required during replacement. As a widely‑used machinery monitoring spare, it is supplied as fully‑tested surplus and refurbished units for maintenance and retrofit of existing 3500 / 3300 monitoring systems.

Core Product Functions

• Non‑contact eddy‑current sensing for shaft radial vibration, thrust position and rotor axial displacement measurement
• Capture key‑phasor pulse signal for rotational speed monitoring and shaft phase‑angle analysis
• Standard 8 mm linear measurement range with stable sensitivity for metal target shaft surface
• Reverse‑mount thread design for installation from back side of bearing housing, suitable for limited‑space machinery assemblies
• Armored integrated cable resists mechanical abrasion, vibration and electromagnetic interference in field environments
• Miniature ClickLoc coaxial connector ensures reliable connection with extension cable, preventing loose signal faults
• Full interchangeability with 3300 XL series proximitors and extension cables without component‑matching calibration
• Wide operating temperature adaptability, stable performance for turbine, compressor and generator bearing‑chamber conditions

• Output analog gap signal to proximitor, then transmit processed data to Bently Nevada rack‑based monitoring systems

Application Scenarios

• Vibration and displacement monitoring for steam turbine, gas turbine and generator sets in thermal power plants
• Critical compressor, pump and turbo‑machinery condition monitoring in oil & gas and petrochemical plants
• Rotating‑machinery protection systems based on Bently Nevada 3500 and 3300 monitor racks
• Offshore platform and marine power‑generation equipment shaft condition monitoring applications
• Captive power station, metallurgy and heavy‑industry critical rotating equipment predictive maintenance systems
• Spare replacement proximity probe for maintenance, troubleshooting and retrofit of legacy Bently Nevada machinery monitoring installations

FAQ (Frequently Asked Questions)

• Q: Abnormal jump or zero drift of monitoring readings after installing 330106‑05‑30‑05‑02‑05?
  A: Check probe mounting gap, coaxial connector locking status, cable damage, target shaft surface condition and proximitor configuration parameters.
• Q: Can I mix‑use this reverse‑mount probe with ordinary forward‑mount probe extension cables?
  A: 3300 XL series supports interchangeability; verify cable length matching to ensure total system electrical length complies with specification before commissioning.
• Q: What will happen if probe tip collides with rotating shaft?
  A: Probe tip will get damaged, measurement linearity fails; stop unit and inspect shaft surface, replace damaged probe and re‑set installation gap.
• Q: Can this probe work with non‑Bently Nevada third‑party proximitor or monitoring modules?
  A: Optimized for Bently Nevada 3300 XL proximitor; third‑party hardware may cause sensitivity deviation and inaccurate measurement results.
• Q: Is BENTLY NEVADA 330106‑05‑30‑05‑02‑05 available for brand‑new machinery monitoring projects?
  A: This legacy proximity probe has reached end‑of‑life. Only fully‑tested surplus and refurbished units are offered for existing‑site maintenance and retrofit tasks.
