Bently Nevada 330101-00-33-05-02-00 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Technical Specifications Breakdown

Key parameters for the 330101-00-33-05-02-00 are listed below for quick reference:

Industry Applications

The 8 mm diameter provides a thicker PPS encapsulation, offering better protection against physical abuse compared to smaller probes. In oil and gas facilities, the optional FluidLoc cable prevents liquid leakage through the cable interior, maintaining machine integrity. The 0.5 m cable length suits installations where the Proximitor sensor is mounted close to the machine.

Installation and Setup Guidance

When installing the 330101-00-33-05-02-00, ensure the target surface is clean and within the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. The maximum distance between the Proximitor sensor and the monitor is 305 meters (1,000 feet). Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal.

Maintenance and Reliability

Inspect the probe and cable periodically for physical damage, especially at the connector and tip. The patented CableLoc design provides 330 N (75 lbf) pull strength, but avoid excessive bending near the probe tip. The probe is designed to seal differential pressure using a Viton O-ring; if pressure sealing is critical, contact the custom design department for testing. Verify the incremental scale factor remains within ±5% over the 80 mil linear range at operating temperatures.

Reliable Vibration Sensing for Critical Machinery

For maintenance engineers overseeing rotating equipment, the Bently Nevada 330101-00-33-05-02-00 3300 XL 8 mm Probe offers a robust solution for eddy-current vibration monitoring. Designed with a 3/8-24 UNF thread and without armor, this probe provides accurate displacement measurements essential for predictive maintenance and machine protection. Its patented TipLoc and CableLoc designs enhance durability, reducing the risk of probe failure in demanding industrial environments.

Compatibility and Integration

The miniature coaxial ClickLoc connector ensures a secure, quick connection without special tools. For extended temperature range applications, the probe tip can withstand up to +218°C (+425°F) with the ETR option.

Selection Guide and Purchasing Advice

When selecting a replacement probe, verify the thread type (3/8-24 UNF) and total length (0.5 meter). The 330101-00-33-05-02-00 is a standard configuration without armor, suitable for most industrial environments. For applications requiring additional cable protection, consider the armored version.
