330101-00-13-10-02-00 | Bently Nevada 8 mm Probe 3/8-24 UNF

Introduction to the Bently Nevada 330101-00-13-10-02-00

When machine vibration threatens uptime, the 330101-00-13-10-02-00 from Bently Nevada provides the precise measurement you need. This 3300 XL 8 mm probe features a 3/8-24 UNF thread and a 1.0 meter (3.3 feet) total length, making it a reliable choice for industrial rotating machinery monitoring.

Part of the trusted 3300 XL series, this probe is engineered for durability and accuracy. Its patented TipLoc molding method creates a robust bond between the probe tip and body, while the CableLoc design provides 330 N (75 lbf) pull strength to secure the cable and tip. These features help prevent common failures caused by vibration and physical stress.

Key Features and Technical Specifications

The 330101-00-13-10-02-00 is built to deliver consistent performance in demanding environments. Here are the core specifications you can rely on:

• Probe Type: 3300 XL 8 mm probe with 3/8-24 UNF thread, without armor
• Overall Case Length: 1.3 inches (option 13)
• Total Length: 1.0 meter (3.3 feet) (option 10)
• Connector: Miniature coaxial ClickLoc connector with standard cable (option 02)
• Linear Range: 2 mm (80 mils), from 0.25 to 2.3 mm (10 to 90 mils)
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% for standard 1 meter system
• Deviation from Straight Line (DSL): Less than ±0.025 mm (±1 mil) for standard 1 meter system
• Probe Tip Material: Polyphenylene sulfide (PPS)
• Probe Case Material: AISI 303 or 304 stainless steel
• Operating Temperature: -52°C to +177°C (-62°F to +350°F) for standard probe

One distinctive spec is the linear range of 2 mm (80 mils), which gives you a wide measurement window for accurate vibration monitoring. This range, combined with the high pull strength of 330 N (75 lbf), ensures reliable readings even in harsh conditions.

Applications and Use Cases

The 330101-00-13-10-02-00 is ideal for monitoring radial vibration in turbines, compressors, pumps, and other rotating equipment. Its 8 mm probe design provides a thicker encapsulation of the probe coil, offering enhanced robustness against physical abuse. This makes it suitable for applications where probe durability is critical.

For example, in a steam turbine train, this probe can be mounted to continuously monitor shaft vibration, helping you detect imbalance or misalignment early. The probe's linear range and scale factor allow precise tracking of vibration amplitude, enabling predictive maintenance strategies that reduce unplanned downtime.

Installation and Setup

Proper installation is key to achieving accurate measurements. The probe case thread is 3/8-24 UNF, and the maximum thread engagement length is 0.563 inches. For standard forward-mounted probes, the recommended torque is 11.2 N•m (100 in•lbf), with a maximum rated torque of 33.9 N•m (300 in•lbf). For the first three threads, use a recommended torque of 7.5 N•m (66 in•lbf) and a maximum of 22.6 N•m (200 in•lbf).

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

Maintenance and Reliability

To maintain reliable performance, inspect the probe periodically for physical damage or wear. The probe is designed to seal differential pressure between the tip and case, using a Viton® O-ring. Note that probes are not pressure tested prior to shipment; if your application requires a pressure seal test, contact the custom design department.

The probe operates in temperatures from -52°C to +177°C, but exposing it to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Regular inspection per the manufacturer's manual helps ensure long service life and consistent measurement accuracy.

Compatibility and Integration

The 330101-00-13-10-02-00 is designed to work with Bently Nevada 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector ensures a secure and reliable connection. This probe is part of a comprehensive monitoring system that can integrate with your existing vibration monitoring infrastructure.
