Bently Nevada 330101-00-72-10-12-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Technical Specifications Breakdown

Key parameters for the 330101-00-72-10-12-05 are listed below for quick reference:

Industry Applications

In oil and gas facilities, the 330101-00-72-10-12-05 helps detect early bearing wear and shaft misalignment, preventing unplanned downtime. Power generation plants use it for turbine supervisory systems where accurate gap voltage and linear output are critical.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread with a recommended torque of 11.2 N•m (100 in•lbf) for standard forward mounting. For the first three threads, use 7.5 N•m (66 in•lbf). Ensure the target surface is clean and free of coatings. Set the initial gap to achieve –9 Vdc output, which corresponds to approximately 1.27 mm (50 mils) from the target. Use three-conductor shielded triad cable for field wiring, with a maximum length of 305 meters (1,000 feet) between the proximitor and monitor.

Maintenance & Reliability

The probe’s PPS tip and stainless steel case resist chemical exposure and mechanical abuse. The patented TipLoc and CableLoc designs provide 330 N (75 lbf) pull strength, reducing the risk of cable detachment. Inspect the connector and cable periodically for signs of wear or fluid ingress. The probe operates reliably in humidity up to 93% with less than 3% change in Average Scale Factor (ASF).

Robust Vibration Monitoring for Critical Machinery

When protecting rotating assets like turbines, compressors, and pumps, the sensor interface must withstand harsh environments and deliver precise data. The Bently Nevada 330101-00-72-10-12-05 is a 3300 XL 8 mm probe designed for reliable proximity measurement in demanding industrial settings. Its 3/8-24 UNF thread and robust construction make it a preferred choice for permanent vibration monitoring systems.

Compatibility & Integration

This probe is part of the 3300 XL system and works with Bently Nevada proximitors and monitors that accept 8 mm probe inputs. The miniature coaxial ClickLoc connector ensures secure, quick installation. The CSA, ATEX, and IECEx approvals allow use in hazardous areas classified for gas and dust.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), overall length, and cable type. The 330101-00-72-10-12-05 is a 1.0 meter system without armor, suitable for standard clearance holes. For applications requiring higher temperature tolerance, consider the extended temperature range option. Contact AutoDCSTech for availability and lifecycle status before ordering.
