Bently Nevada 330103-00-05-10-01-CN 3300 XL 8 mm Proximity Probe

Description

Serving as a high-precision component in industrial machinery protection architectures, this Bently Nevada 330103-00-05-10-01-CN proximity probe enables continuous, non-contacting measurement of shaft dynamic vibration and static position. Designed for integration with the 3300 XL 8 mm Proximity Transducer System, this configuration features a threadless case geometry, robust mechanical seals, and specialized hardware protections to withstand hostile industrial environments. It provides reliable output signals representing the distance between the target shaft and the probe tip, directly interfaceable with vibration monitors and machinery diagnostics platforms.

Features

• Threadless Case Geometry: Designed with a 0 mm unthreaded option and 50 mm total case length for specific bracket-mounted machinery housings.
• High-Performance Tip Material: Constructed from polyphenylene sulfide (PPS) to resist aggressive chemical attack and high thermal exposure.
• Integrated ClickLoc Connector: Miniature coaxial ClickLoc connector paired with a factory-installed connector protector prevents physical damage and connection degradation.
• Viton Pressure Seal: Employs an internal Viton O-ring to establish a secure differential pressure seal between the probe tip and case assembly.
• Regional Approval Certification: Provided with CN option code, certifying compliance with localized industrial safety regulations.

Applications

• Radial vibration monitoring of high-speed steam and gas turbine shafts.
• Thrust position measurement in heavy-duty centrifugal compressors.
• Eccentricity and phase reference (Keyphasor) detection on industrial generators.
• Shaft alignment and displacement tracking in nuclear reactor coolant pumps.

Alternative Models & Compatibility

This probe utilizes a 1.0-meter integral cable configuration. It must only be paired with a Proximitor sensor specifically configured for a 1.0-meter system length (resulting in a 5.0-meter or 9.0-meter total system length when combined with extension cables). Connecting this probe to a Proximitor designed for 0.5-meter systems will lead to calibration distortion, causing substantial output voltage measurement errors.

Application Pitfalls & Engineering Notes

Because this is a threadless 50 mm case probe, ensure the mounting clamp or sleeve provides sufficient gripping surface without deforming the outer stainless steel sleeve. A minimum clearance of 40 mm (1.6 inches) must be maintained between adjacent proximity probes to avoid mutual electromagnetic field interference, commonly referred to as cross-talk.

Commissioning & Wiring Tips

When joining the gold-plated miniature coaxial ClickLoc connector to the extension cable, clean the contacts with electronic contact cleaner before connection. The factory-provided connector protector must be fully secured over the junction. When securing the probe inside bracket mounts, verify that the Viton O-ring is properly positioned in the groove to prevent process fluids from bypassing the mounting surface.
