330101-00-14-10-02-05 | Bently Nevada 8 mm Probe 3/8-24 UNF

Introduction to the Bently Nevada 330101-00-14-10-02-05

When machinery vibration threatens uptime, the 330101-00-14-10-02-05 from Bently Nevada provides the precise measurement you need. This 3300 XL 8 mm probe is engineered for demanding rotating equipment applications, delivering accurate displacement data that helps maintenance teams detect issues early.

As part of the trusted 3300 XL series, this probe features a 3/8-24 UNF thread and a robust design that withstands harsh industrial environments. The model number 330101-00-14-10-02-05 indicates a 1.0 metre total length, a miniature coaxial ClickLoc connector, and CSA, ATEX, and IECEx approvals for hazardous area use.

Key Features and Technical Specifications

The 330101-00-14-10-02-05 offers several standout features that make it a reliable choice for vibration monitoring:

• Probe Type: 3300 XL 8 mm probe with 3/8-24 UNF thread, without armor.
• Total Length: 1.0 metre (3.3 feet) – ideal for standard installations.
• Connector: Miniature coaxial ClickLoc connector with standard cable.
• Approvals: CSA, ATEX, and IECEx certified for use in explosive atmospheres.
• Linear Range: 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target.
• Incremental Scale Factor: 7.87 V/mm (200 mV/mil) ±5% for standard 5 or 1 meter systems.
• Probe Tip Material: Polyphenylene sulfide (PPS) for durability.
• Probe Case Material: AISI 303 or 304 stainless steel.

These specifications ensure accurate, repeatable measurements even in challenging conditions. The patented TipLoc molding method provides a robust bond between the probe tip and body, reducing the risk of mechanical failure.

Applications and Use Cases

The 330101-00-14-10-02-05 is well-suited for monitoring radial vibration in turbines, compressors, pumps, and other rotating machinery. Its 8 mm probe design offers thicker encapsulation of the probe coil, making it more rugged and resistant to physical abuse.

In addition, the optional FluidLoc cable option prevents oil and other liquids from leaking out of the machine through the cable interior, which is critical in applications where fluid contamination is a concern. This probe is also approved for use in hazardous areas, making it a versatile choice for oil and gas, chemical, and power generation facilities.

Installation and Setup

Proper installation is essential for accurate readings. The 330101-00-14-10-02-05 uses a 3/8-24 UNF thread, so ensure the mounting hole is tapped to the correct specification. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils) from the target.

Field wiring should use a 3-conductor shielded triad cable with tinned wiring, sized between 0.2 to 1.5 mm² (16 to 24 AWG). The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Always follow the manufacturer's installation manual for detailed procedures.

Maintenance and Reliability

To maintain reliable performance, inspect the probe periodically for signs of wear or damage. The probe is designed to seal differential pressure between the tip and case, using a Viton® O-ring. Avoid exposing the probe to temperatures below -34°C (-30°F), as this may cause premature failure of the pressure seal.

Regularly verify the probe's DC resistance and scale factor to ensure it remains within specification. For extended temperature range probes, the operating range is -52°C to +218°C for the tip, and -51°C to +260°C for the cable and connector. Following these guidelines helps extend the service life of the probe.

Compatibility and Integration

The 330101-00-14-10-02-05 is designed to work with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a secure, reliable connection. The probe's linear range and scale factor are optimized for use with standard 3300 XL system components.

For integration, ensure that the total system length (probe plus extension cable) matches the calibration requirements. The standard 5 or 1 meter system provides an incremental scale factor of 7.87 V/mm ±5%, while the 9 meter system offers ±6.5%. This compatibility simplifies replacement and upgrades in existing installations.

Troubleshooting and Common Issues

If you encounter erratic readings, first check the probe tip for damage or contamination. Verify that the gap setting is within the recommended range of -9 Vdc. Also, inspect the cable for cuts or kinks that could affect signal integrity.

Another common issue is moisture ingress. The optional FluidLoc cable option can help prevent liquid from entering the machine through the cable. If the probe is exposed to high humidity, the average scale factor may change by less than 3%, which is within acceptable limits. For persistent problems, consult the official Bently Nevada documentation or contact Petro Auto Tech for support.
