Bently Nevada 330104-00-14-10-02-05 3300 XL 8 mm Proximity Probe

Product Introduction

When rotating machinery vibration threatens unplanned downtime, the Bently Nevada 330104-00-14-10-02-05 3300 XL 8 mm Proximity Probe delivers precise, reliable displacement measurement. This probe is part of the proven 3300 XL series, designed for continuous monitoring in critical applications such as steam turbines, compressors, and pumps. Its robust construction and agency approvals make it a trusted choice for safety-instrumented systems.

Technical Specifications Breakdown

The 330104-00-14-10-02-05 features a polyphenylene sulfide (PPS) probe tip and an AISI 303 or 304 stainless steel case, ensuring durability in corrosive and high-temperature environments. The probe is designed to seal differential pressure between tip and case using a Viton O-ring. Electrical performance is specified with a -24 Vdc power supply and 10 kΩ load, delivering less than 2 mV change in output voltage per volt change in input voltage. The nominal DC resistance for a 1.0 meter probe is 7.59 ± 0.50 ohms. Agency approvals include CSA, ATEX, and IECEx, confirming its suitability for hazardous area installations.

Industry Applications

In petrochemical plants, the 330104-00-14-10-02-05 monitors shaft vibration and position in large centrifugal compressors. Its stainless steel case resists process chemicals, while the PPS tip withstands high temperatures. For power generation, this probe provides critical data for turbine supervisory systems, helping operators detect early signs of bearing wear or imbalance. The CSA, ATEX, and IECEx approvals simplify global deployment in Zone 1 and Zone 2 areas.

Installation & Setup Guidance

Proper gap setting is essential for accurate measurement. The probe should be gapped at 1.27 mm (50 mils) per standard calibration. Use the M10 x 1 thread for mounting, and ensure the unthreaded length is 00 mm. The overall case length is 140 mm, and the total length is 1.0 meter (3.3 feet). Connect the miniature coaxial ClickLoc connector securely to the extension cable. Verify that the power supply meets the -17.5 Vdc to -26 Vdc requirement (or -23 Vdc to -26 Vdc with barriers) to maintain linear range.

Maintenance & Reliability

Regular inspection of the probe tip and cable for physical damage is recommended. The Viton O-ring seal should be checked during each shutdown to ensure differential pressure integrity. Because the probe is part of a safety-critical monitoring loop, follow the manufacturer's guidelines for periodic verification of system accuracy. The robust stainless steel case and PPS tip provide long service life in demanding environments, reducing total cost of ownership.

Compatibility & Integration

The 330104-00-14-10-02-05 accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm Proximity Probe and Extension Cable. It works with 3300 XL Proximitor Sensors and extension cables to form a complete transducer system. The system accuracy and interchangeability specifications apply only when using 3300 XL 8 mm components and an AISI 4140 steel target. For integration with existing monitoring systems, consult the installation drawing 140979.

Buying Guide & Purchasing Advice

Before ordering, verify that the probe length and connector type match your application requirements. The 330104-00-14-10-02-05 includes the 1.0 meter cable with miniature coaxial ClickLoc connector. For hazardous area use, confirm that the agency approval option (05: CSA, ATEX, IECEx) meets your local regulations. plcmatrix.com offers this probe as a new or surplus unit, with fast shipping and expert support to help you select the correct configuration.
