Bently Nevada 330104-00-22-10-01-05 3300 XL 8 mm Proximity Probe

Product Introduction

When reliable vibration and position monitoring is non-negotiable, the Bently Nevada 330104-00-22-10-01-05 delivers precision measurement for rotating machinery. Part of the 3300 XL 8 mm Proximity Probe series, this probe provides non-contact sensing of shaft displacement and eccentricity. Designed for harsh industrial environments, it features a robust construction with armor and a miniature coaxial ClickLoc connector. The 330104-00-22-10-01-05 is an essential component for predictive maintenance programs in power generation, oil and gas, and heavy manufacturing.

Technical Specifications Breakdown

The 330104-00-22-10-01-05 probe offers a nominal DC resistance of 7.59 ± 0.50 Ω at 1.0 meter length. This ensures consistent signal transmission for accurate gap voltage measurements. The probe tip material is polyphenylene sulfide (PPS), providing excellent chemical resistance and dielectric strength. The probe case is made from AISI 303 or 304 stainless steel (SST), offering durability in corrosive environments. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring, making it suitable for high-pressure applications.

For optimal performance, the system should be used with a -24 Vdc power supply and a 10 kΩ load, with the probe gapped at 1.27 mm (50 mils) against an AISI 4140 steel target. The system accuracy and interchangeability specifications apply only when using 3300 XL 8 mm components and the specified target material.

Industry Applications

In steam turbine monitoring, the 330104-00-22-10-01-05 measures shaft radial vibration and thrust position, enabling early detection of bearing wear or misalignment. For centrifugal compressors in gas processing plants, this probe provides critical data for surge control and balance monitoring. Its CSA, ATEX, and IECEx approvals allow installation in hazardous areas, including Class I, Zone 0 and Zone 2 environments. The probe's temperature schedule supports ambient temperatures from -55°C to +232°C (T1 classification), ensuring reliable operation in extreme conditions.

Installation and Setup Guidance

Proper installation of the 330104-00-22-10-01-05 requires careful attention to thread engagement and gap setting. Use the M10 x 1 thread with appropriate locking hardware to secure the probe. The overall case length is 220 mm, and the total length is 1.0 meter (3.3 feet). Ensure the probe tip is clean and free of debris before mounting. Connect the miniature coaxial ClickLoc connector to the extension cable, using the connector protector to prevent damage. Verify the system linearity by performing a static calibration against a target of known material (AISI 4140 steel recommended).

Maintenance and Reliability

Regular inspection of the probe tip and cable assembly helps maintain measurement accuracy. Check for physical damage, contamination, or corrosion on the PPS tip and stainless steel case. The Viton O-ring seal should be inspected periodically for signs of wear or leakage. Environmental factors such as high temperature, humidity, or chemical exposure can affect probe life; the 330104-00-22-10-01-05 is designed to withstand these conditions, but routine checks extend service life. For systems installed with intrinsically safe barriers or galvanic isolators, follow the applicable installation drawings (141092 or 140979) to maintain safety integrity.

Compatibility and Integration

The 330104-00-22-10-01-05 works exclusively with 3300 XL 8 mm Proximitor Sensors and extension cables. It accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm probe. The power requirement ranges from -17.5 Vdc to -26 Vdc when installed with non-incendive circuits, and -23 Vdc to -26 Vdc with barriers. The output resistance is 50 Ω, and sensitivity is less than 2 mV change per volt change in input voltage. For integration into existing monitoring systems, ensure the power supply and load match the specified conditions.

Selection Guide and Purchasing Advice

Before ordering the 330104-00-22-10-01-05, verify that your application requires the 8 mm probe diameter, M10 x 1 thread, and armored cable. Confirm the agency approval option (05) meets your site's hazardous area classification: CSA, ATEX, or IECEx. The probe is designed for use with AISI 4140 steel targets; using other materials may affect accuracy. For current availability and lifecycle status, contact plcmatrix.com.
