Bently Nevada 330104-00-10-20-02-05 3300 XL 8 mm Proximity Probe

Description

Option 00 (0 mm unthreaded length), Option 10 (100 mm overall case length), and Option 20 (2.0 meters total length) specify this 3300 XL 8 mm metric proximity probe configuration with integral stainless steel armor — 330104-00-10-20-02-05. This eddy-current non-contact sensor measures shaft vibration, radial position, and axial thrust displacement on rotating machinery. Unlike unarmored models, the 330104 series includes integral stainless steel armor that shields the coaxial cable from physical damage, abrasive wear, and harsh industrial environments.

The 330104 probe operates as part of a complete 3300 XL 8 mm proximity transducer system, which requires a matching extension cable and a 3300 XL Proximitor sensor. It utilizes a metric M10 x 1 thread with a 100 mm total case length, featuring a fully threaded design (0 mm unthreaded portion) for secure mounting within standard brackets or custom housings. The integrated 2.0-meter cable is terminated with a miniature coaxial ClickLoc connector and is certified for hazardous areas under Option 05 approvals.

Features

• Integral stainless steel armor protects the coaxial cable from mechanical impact, abrasion, and environmental exposure.
• M10 x 1 metric thread design with a 100 mm case length and 0 mm unthreaded portion for deep-insertion or flush-mount applications.
• Integrated 2.0-meter coaxial cable with a miniature ClickLoc connector for reliable signal transmission to the extension cable.
• Option 05 agency approvals include CSA, ATEX, and IECEx certifications for installation in hazardous environments.
• Polyphenylene sulfide (PPS) plastic probe tip is molded with a thicker encapsulation to withstand chemical attack and high temperatures.

Applications

This proximity probe is used for continuous condition monitoring of rotating machinery across various heavy industries, including power generation, oil and gas, petrochemicals, and water treatment. Typical installation scenarios include:

• Radial shaft vibration and dynamic position measurement on industrial steam and gas turbines.
• Thrust (axial) position monitoring on high-pressure centrifugal compressors and pumps.
• Eccentricity and phase reference (Keyphasor) measurement on turbogenerators and electric motors.
• Casing expansion and differential expansion monitoring on utility turbomachinery.

Installation Guidelines

When installing the proximity probe, adhere to the following engineering practices:

• Thread Engagement: The maximum thread engagement length for M10 x 1 threads is 15 mm. Exceeding this length may cause binding during installation.
• Probe Gap Calibration: Typically gapped at 1.27 mm (50 mils) to establish the midpoint of the linear range, corresponding to approximately -10 Vdc output on a standard Proximitor sensor.
• Armor Handling: Ensure that the stainless steel armor does not rub against sharp edges. Maintain a minimum bend radius of 30.5 mm to prevent kinking or internal conductor damage.
• Grounding and Shielding: Maintain electrical isolation between the coaxial connector outer shield and the machine casing. Connect the shield only at the Proximitor sensor end to prevent ground loops.

Compliance and Certifications

This configuration (Option 05) is certified for use in hazardous areas and meets the following standards:

• CSA: Class I, Division 1 & 2, Groups A, B, C, D
• ATEX: Ex ia IIC T1...T5 Ga; Zone 0/1/2
• IECEx: Ex ia IIC T1...T5 Ga
