Bently Nevada 330103-00-03-10-01-00 3300 XL 8 mm Proximity Probe

Description

Featuring an M10 x 1 metric threaded body with 0 mm unthreaded length (Option 00) and a 30 mm case length (Option 03), the Bently Nevada 330103-00-03-10-01-00 3300 XL 8 mm proximity probe provides non-contact shaft vibration and axial position measurement. This configuration includes a 1.0-meter total length cable (Option 10) terminated with a miniature coaxial ClickLoc connector with an integrated connector protector (Option 01). It is designed without stainless steel protective armor (separating it from the armored 330104 series) and requires no hazardous area agency approvals (Option 00).

This probe operates as a critical component in the 3300 XL 8 mm Transducer System, paired with a matching standard extension cable and a 3300 XL Proximitor sensor. Utilizing eddy-current technology, it translates the physical distance between the probe tip and a target (typically AISI 4140 steel) into a proportional voltage signal. With its short 1.0-meter cable length, this probe is ideal for installations where the extension cable junction is located in close proximity to the probe mount, eliminating excessive cable looping inside the machine housing.

Features

• M10 x 1 Metric Thread: Allows direct installation into metric machine housings without specialized thread adapters.
• Fully Threaded Body: Standard 0 mm unthreaded length (Option 00) allows the entire 30 mm case to be used for secure mounting depth adjustment.
• Pre-installed Connector Protector: Option 01 incorporates a protective sleeve over the miniature ClickLoc connection to shield against environmental contamination.
• 1.0-Meter Cable Length: Minimizes cable slack inside tight machinery enclosures while keeping connection paths compact.
• Unarmored Mechanical Construction: Offers maximum routing flexibility and lightweight cable installation for non-abrasive environments.
• Standard Temperature Rating: Capable of withstanding harsh physical and temperature conditions on rotating machinery.

Applications

The 330103-00-03-10-01-00 probe is used in critical rotating machinery protection systems across diverse industrial environments, including:

• Steam and gas turbine shaft vibration and axial thrust position tracking.
• Centrifugal and reciprocating compressor radial shaft vibration analysis.
• Industrial gearbox shaft monitoring and bearing clearance checks.
• Generators and pumps where metric mounting interfaces are standard.

Technical Specifications

Connections and Interfaces

The probe utilizes a coaxial signal loop for high-frequency measurement excitation and signal transmission to the matching extension cable.

Installation Guidelines

Ensure correct mechanical installation and connection practices to prevent physical and performance degradation:

• Torque Limits: Tighten the probe case to 7.5 N-m (66 in-lbf). Exceeding the maximum limit of 22.6 N-m (200 in-lbf) will damage external threads.
• Maximum Thread Engagement: Ensure thread depth engagement does not exceed 15 mm to avoid binding during installation.
• Connector Protection: Once the ClickLoc coaxial connection is established, slide the integrated Option 01 connector protector sleeve over the interface. This provides reliable environmental protection.
• Cable Bending: Do not route the triaxial cable at an angle tighter than the minimum bend radius of 25.4 mm (1.0 in).

Compliance and Certifications

This general-purpose configuration is not rated for explosive or hazardous environments:

• Hazardous Area Rating: Option 00 (Not required). This specific model does not carry CSA, ATEX, or IECEx certifications.
• CE Compliance: Compliant with industrial electromagnetic compatibility directive requirements when fully shielded in accordance with installation manual instructions.
• RoHS: Compliant with the restriction of hazardous substances.
