300103-00-05-10-02-CN | Bently Nevada 8 mm Proximity Probe, 1.0 m

Introduction: The Evolution of Vibration Monitoring

For decades, industrial rotating machinery has demanded reliable, accurate vibration monitoring to prevent catastrophic failures. Early systems relied on simple mechanical sensors, but the industry has evolved toward advanced eddy-current proximity probes that measure shaft vibration and position with exceptional precision. The 300103-00-05-10-02-CN from Bently Nevada represents this evolution, offering a robust 8 mm probe design engineered for demanding environments.

As part of the 3300 XL series, this probe provides the high-resolution data needed for predictive maintenance and machinery protection. Whether you are upgrading an aging system or specifying new equipment, the 300103-00-05-10-02-CN delivers the performance and reliability that modern plants require.

Key Features and Technical Specifications

The 300103-00-05-10-02-CN is a 3300 XL 8 mm proximity probe with a total length of 1.0 meter (3.3 feet). It features a miniature coaxial ClickLoc connector and standard cable, ensuring secure and reliable connections. The probe tip is made of polyphenylene sulfide (PPS), while the probe case is constructed from AISI 303 or 304 stainless steel (SST), providing excellent durability and corrosion resistance.

• Probe type: 3300 XL 8 mm proximity probe
• Total length: 1.0 meter (3.3 feet)
• Connector: Miniature coaxial ClickLoc
• Probe tip material: Polyphenylene sulfide (PPS)
• Probe case material: AISI 303 or 304 stainless steel (SST)
• Agency approval: Country Specific Approval (CN)

One distinctive feature is the probe's linear range of 2 mm (80 mils), which begins at approximately 0.25 mm (10 mils) from the target and extends to 2.3 mm (90 mils). This wide linear range allows accurate measurement across typical vibration amplitudes, making the 300103-00-05-10-02-CN suitable for a variety of rotating machinery applications.

Applications and Use Cases

In turbomachinery, compressors, and pumps, the 300103-00-05-10-02-CN provides critical shaft vibration and position data. Consequently, maintenance teams can detect early signs of imbalance, misalignment, or bearing wear before they lead to unplanned downtime. Moreover, the probe's robust construction ensures reliable operation in harsh industrial environments, including those with high humidity or temperature extremes.

For example, in a steam turbine application, the probe monitors radial vibration, allowing operators to adjust operating conditions and extend equipment life. Therefore, the 300103-00-05-10-02-CN is an essential component for any comprehensive machinery protection system.

Installation and Setup

Proper installation is crucial for accurate measurements. The 300103-00-05-10-02-CN features an M10 x 1 thread, with a maximum thread engagement length of 15 mm. During installation, ensure the probe is mounted securely and the gap is set to the recommended -9 Vdc, approximately 1.27 mm (50 mils), for radial vibration measurements. Field wiring should use a 3-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the probe and the monitor. Always follow the manufacturer's guidelines to achieve optimal performance.

Maintenance and Reliability

Routine inspection of the probe and its connections is essential to maintain reliable operation. The probe's PPS tip and stainless steel case resist corrosion and wear, but periodic checks for physical damage or contamination are recommended. Additionally, the probe is designed to seal differential pressure between the tip and case, using a Viton® O-ring. Therefore, avoid exposing the probe to temperatures below -34°C (-30°F), as this may cause premature failure of the pressure seal. By following these simple maintenance practices, you can extend the service life of the 300103-00-05-10-02-CN and ensure consistent monitoring accuracy.

Compatibility and Integration

The 300103-00-05-10-02-CN is part of the Bently Nevada 3300 XL family, designed to work seamlessly with 3300 XL Proximitor sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a secure and reliable connection, while the standard cable allows for straightforward integration into existing installations. For hazardous area applications, the probe can be installed with intrinsically safe zener barriers per drawing 141092 or with galvanic isolators, meeting Class I, Zone 0 requirements (AEx/Ex ia IIC T5...T1 Ga). Additionally, when connected with nonincendive circuits per drawing 140979, it is suitable for Class I, Zone 2 applications (AEx/Ex nA IIC T5…T1 Gc and AEx/Ex ec IIC T5…T1 Gc).
