Bently Nevada 330103-00-11-50-02-05 3300 XL 8 mm Proximity Probe

Description

Option 00 (0 mm unthreaded length) and Option 11 (110 mm case length) specify this metric, unarmored 3300 XL 8 mm proximity probe configuration — 330103-00-11-50-02-05. This configuration incorporates a 5.0-meter total cable length (Option 50) and a miniature ClickLoc coaxial connector (Option 02), paired with CSA, ATEX, and IECEx hazardous area approvals (Option 05). Designed without mechanical armor, this model utilizes an M10 x 1 metric thread for direct installation into tapped machine housings where external protection is provided by conduit or the machine casing itself.

This configuration differs from imperial alternatives like the 330101 series by using metric threads and dimensions. Unlike armored variants such as the 330104 series, this unarmored probe uses standard coaxial cable, which provides superior routing flexibility in tight spaces. The 5.0-meter total length means the probe connects directly to a 5-meter Proximitor sensor without requiring an intermediate extension cable, reducing potential signal losses and connector failure points in the measurement chain.

Features

• Metric M10 x 1 thread pattern specifically engineered for metric-standard machine casings.
• Option 00 fully threaded probe body with 0 mm unthreaded length for solid mounting stability.
• Option 11 overall case length of 110 mm to reach deep within standard machine housings.
• Option 50 total cable length of 5.0 meters, allowing direct Proximitor sensor connection.
• Option 02 ClickLoc miniature coaxial connector provides positive connection locking without special tools.
• Option 05 agency approvals allow safe installation in CSA, ATEX, and IECEx certified hazardous environments.
• PPS plastic probe tip material resists mechanical impacts and aggressive chemical environments.

Applications

This proximity probe is used in critical rotating machinery protection systems for measuring parameters such as:

• Radial shaft vibration
• Axial shaft position / thrust position
• Eccentricity measurements
• Phase reference (Keyphasor) sensing
• Casing expansion and differential expansion

Technical Specifications

Connections and Interfaces

The probe utilizes a standard miniature ClickLoc coaxial connector interface to connect to the Proximitor sensor:

Installation Guidelines

• Probe Gap: Gap the probe to 1.27 mm (50 mils) to achieve the nominal center of the 2.0 mm (80 mils) linear range.
• Thread Engagement: Ensure thread engagement does not exceed 15 mm for the M10 x 1 case thread to avoid binding or damage.
• Cable Routing: Route the standard coaxial cable inside protective conduit or structural channels to shield it from mechanical damage and abrasive contact.
• Connector Tightening: Tighten gold ClickLoc connectors finger-tight. Avoid using pliers as it can damage the miniature coaxial connection.
• Environmental Protection: Ensure the cable-to-extension connector interface is insulated or protected from moisture and turbine oil contamination.

Compliance and Certifications

• CSA: Approved for Class I, Division 1 and 2, Groups A, B, C, and D hazardous locations when installed with appropriate barriers.
• ATEX: II 1 G Ex ia IIC T1...T5 Ga/Gb
• IECEx: Ex ia IIC T1...T5 Ga/Gb
