Description

Option 000 (0 mm unthreaded length) and Option 050 (50 mm overall case length) specify this armored metric proximity probe configuration — 330704-000-050-10-02-05.

This Bently Nevada 3300 XL 11 mm proximity probe features an M14 x 1.5 thread and integrated stainless steel armor. The flexible AISI 302 stainless steel armor is encased in an FEP outer jacket to protect the triaxial cable from physical wear and industrial environmental exposure. Unlike standard unarmored configurations, this version is designed for direct exposure to abrasive elements. The 1.0 meter triaxial cable terminates in a miniature coaxial ClickLoc connector (Option 02). It is compatible with the 3300 XL 11 mm transducer system, which provides a linear measurement range of 4.0 mm (160 mils) and an output scale factor of 3.94 V/mm (100 mV/mil) for non-contacting displacement monitoring.

Features

• M14 x 1.5 metric thread with integrated flexible AISI 302 stainless steel armor and protective FEP jacket
• Option 000 specifies 0 mm unthreaded length for a fully threaded case
• Option 050 specifies 50 mm overall case length
• Option 10 specifies a total probe and lead length of 1.0 meter (3.3 feet)
• Option 02 specifies a miniature coaxial ClickLoc connector with standard FEP-insulated cable
• Option 05 Multiple Approvals package covers international hazardous area installations (CSA, ATEX, IECEx)
• Large 11 mm tip diameter supports an extended 4.0 mm (160 mil) linear measurement range
• Polyphenylene sulfide (PPS) probe tip material seals against fluid leakage via an integrated Viton O-ring
• Gold-plated brass connector construction resists corrosion

Applications

• Turbine rotor axial position monitoring
• Thrust bearing wear measurements on large rotating machinery
• Differential expansion measurements on industrial steam turbines
• Rod position and rod drop monitoring on reciprocating compressors
• Non-contact shaft vibration and displacement analysis

Installation Guidelines

• Do not exceed the maximum thread engagement length of 21 mm for M14 x 1.5 threads to avoid binding during installation.
• Ensure that external probe threads match the internal mounting threads (M14 x 1.5) before attempting installation.
• Apply the recommended case torque of 21.1 N-m (187 in-lb); do not exceed the maximum rating of 63.3 N-m (560 in-lb).
• Maintain a minimum bend radius of 25.4 mm (1.0 in) along the armored probe lead to avoid internal physical damage.
• Connect the miniature ClickLoc coaxial connectors finger tight; do not exceed 0.565 N-m (5 in-lb) of torque.

Compliance and Certifications

• CE Mark: European Community EMC Directive 2014/30/EU (tested to EN 61000-6-2 and EN 61000-6-4)
• RoHS: European Community ROHS Directive 2011/65/EU
• Hazardous Area Ratings (Option 05 - Multiple Approvals): Certifications for Intrinsic Safety (Ex ia IIC T5...T1 Ga) and Non-Sparking/Increased Safety (Ex nA/Ex ec IIC T4/T5 Gc) under ATEX, IECEx, and CSA standards.
