330101-00-13-15-02-05 | Bently Nevada 8 mm Probe 1.5m

Introduction to the Bently Nevada 330101-00-13-15-02-05

When machinery vibration threatens uptime, the 330101-00-13-15-02-05 from Bently Nevada provides the reliable measurement you need. This 3300 XL 8 mm probe uses a 3/8-24 UNF thread and comes without armor, making it a versatile choice for many industrial applications. With a total length of 1.5 meters (4.9 feet), it fits standard installations while offering the robustness that Bently Nevada is known for.

Key Features and Technical Specifications

• Probe type: 3300 XL 8 mm, 3/8-24 UNF thread, without armor
• Unthreaded length: 0.0 inches
• Overall case length: 1.3 inches
• Total length: 1.5 meters (4.9 feet)
• Connector: Miniature coaxial ClickLoc connector with standard cable
• Approvals: CSA, ATEX, IECEx
• Probe tip material: Polyphenylene sulfide (PPS)
• Probe case material: AISI 303 or 304 stainless steel
• Linear range: 2 mm (80 mils), from approximately 0.25 mm to 2.3 mm (10 to 90 mils)
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% for standard 5 or 1 meter systems

One standout feature is the patented TipLoc molding method, which creates a stronger bond between the probe tip and body. This directly reduces the risk of tip detachment, a common failure point in vibration probes. Additionally, the CableLoc design provides 330 N (75 lbf) pull strength, ensuring the cable stays securely attached even under stress.

Applications and Use Cases

In rotating machinery monitoring, the 330101-00-13-15-02-05 excels at measuring shaft vibration and position. It is ideal for turbines, compressors, pumps, and motors where early detection of imbalance or misalignment prevents costly downtime. Furthermore, its robust construction makes it suitable for harsh environments, including those with high humidity or temperature extremes.

For maintenance engineers, this probe offers a practical solution for predictive maintenance programs. By providing accurate vibration data, it enables condition-based monitoring rather than relying on fixed maintenance schedules. Consequently, you can optimize maintenance intervals and reduce unplanned outages.

Installation and Setup

When installing the 330101-00-13-15-02-05, follow the manufacturer's guidelines for gap setting. The recommended gap for radial vibration is -9 Vdc, which corresponds to approximately 1.27 mm (50 mils). Ensure the probe is mounted securely and the cable is routed without sharp bends to avoid damage.

Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) wire, preferably a 3-conductor shielded triad cable with tinned ends. The maximum distance between the Proximitor Sensor and the monitor is 305 meters (1,000 feet). For longer runs, consult the frequency response graphs to account for signal rolloff at high frequencies.

Maintenance and Reliability

Regular inspection of the probe and cable is essential to maintain accuracy. Check for physical damage, especially at the tip and connector. The probe operates in a temperature range of -52°C to +177°C (-62°F to +350°F) for standard versions, but exposing it to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Therefore, avoid such conditions unless using an extended temperature range probe.

The probe is designed to seal differential pressure between the tip and case, using a Viton® O-ring. However, probes are not pressure tested before shipment. If your application requires pressure seal verification, contact Bently Nevada's custom design department.

Compatibility and Integration

The 330101-00-13-15-02-05 is part of the 3300 XL family and works seamlessly with Bently Nevada monitors and Proximitor sensors. Its miniature coaxial ClickLoc connector ensures a secure and reliable connection, compatible with standard extension cables. For system integration, you can pair it with the 3300 XL extension cable and Proximitor to form a complete measurement chain.

Troubleshooting Common Issues

If you encounter erratic readings, first check the cable connection and continuity. A damaged cable or loose connector can cause signal loss. Also, verify that the probe tip is clean and free from debris, as contamination can affect the linear range. If the probe fails to produce a signal, test the DC resistance between the center and outer conductors; for a 1.5 m probe, the nominal resistance is 7.73 ± 0.50 ohms.

For persistent issues, refer to the official Bently Nevada documentation or contact Petro Auto Tech for technical support.
