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

Description

Option 00 (0 mm unthreaded length), Option 05 (50 mm overall case length), and Option 05 (0.5 m total length) define this armored metric proximity probe configuration - 330104-00-05-05-02-05.

This specific metric-threaded probe is equipped with integral stainless steel armor protecting the standard coaxial cable. Unlike the unarmored 330103 model, the 330104 probe is physically shielded for severe environments where mechanical abrasion, crushing forces, or hot flying debris could damage unprotected cabling. Designed to function seamlessly in a complete 3300 XL 8 mm proximity transducer loop, this 0.5-meter probe must be matched with a compatible extension cable and a 3300 XL Proximitor sensor. Together, they deliver eddy-current displacement measurements to monitor rotor shaft vibration, axial position, and Keyphasor reference speeds on critical rotating machinery.

Features

• Metric Thread Specification: Engineered with an M10 x 1 threaded body (0 mm unthreaded portion) for direct installation in metric threaded machine ports.
• Integral Stainless Steel Armor: Provides mechanical protection for the coaxial cable against abrasion, tearing, and crushing.
• Compact Total Length: Specially configured with a 0.5-meter (1.6 feet) total length (Option 05) to connect directly to nearby bulkheads or standard extension cables.
• Miniature ClickLoc Connector: Built with a gold-plated coaxial ClickLoc connector (Option 02) for low-loss electrical coupling.
• Hazardous Area Certified: Fully certified with CSA, ATEX, and IECEx approvals (Option 05) for intrinsically safe and non-incendive environments.

Applications

• Shaft dynamic vibration and axial static position monitoring on rotating machinery.
• Rotor monitoring in gas, steam, and hydro turbines.
• Continuous condition monitoring of industrial compressors, gearboxes, and large pumps.
• Severe plant environments where cable runs are exposed to physical wear or mechanical abuse.

Installation Guidelines

Proper installation of the 330104-00-05-05-02-05 probe is essential for accurate machinery monitoring and preventing premature failure. Standard installation practices include:

• Thread Engagement: Avoid exceeding the maximum thread engagement of 15 mm inside the mounting bracket or machine casing to prevent binding.
• Probe Gap Calibration: Adjust the physical gap between the probe tip and the target shaft to approximately 1.27 mm (50 mils), corresponding to the midpoint of the system's linear electrical range.
• Cable Handling and Bend Radius: Maintain a minimum bend radius for the armored cable of 25.4 mm (1.0 inch) to preserve coaxial transmission properties and prevent armor deformation.
• Connector Torquing: Connect the miniature gold ClickLoc probe connector to the extension cable coaxial connector finger-tight only. Do not use pliers or excessive force, which can damage the delicate gold-plated components.
• Environmental Protection: Ensure the Viton O-ring is properly seated to maintain the differential pressure seal between the probe tip and the machine casing.

Compliance and Certifications

• ATEX / IECEx: Intrinsically safe (Ex ia IIC T5...T1 Ga) and non-sparking (Ex nA/Ex ec IIC T5...T1 Gc) when used with approved safety barriers or isolators.
• CSA: Certified for Class I, Division 1 and 2, Groups A, B, C, and D hazardous environments.
• EMC: Compliant with EN 61000-6-2 (Immunity for Industrial Environments) and EN 61000-6-4 (Emissions for Industrial Environments).
• RoHS: Compliant with European Community Directive 2011/65/EU and China RoHS regulations.
• Functional Safety: Certified for use in safety-instrumented systems up to SIL 2 (HFT = 0) or SIL 3 (HFT = 1).
