Bently Nevada 330104-00-12-05-02-00 3300 XL 8 mm Proximity Probe

Introduction

When vibration monitoring in rotating machinery demands precision and reliability, the Bently Nevada 330104-00-12-05-02-00 delivers. This 3300 XL 8 mm proximity probe is engineered for non-contact shaft displacement and position measurement in critical assets like turbines, compressors, and pumps. With its M10 x 1 threaded design and built-in armor, it withstands harsh industrial environments while providing consistent performance.

Technical Specifications

The 330104-00-12-05-02-00 features a probe tip made of polyphenylene sulfide (PPS) and a case constructed from AISI 303 or 304 stainless steel (SST). It has an unthreaded length of 00 mm, an overall case length of 12 mm, and a total length of 0.5 meter (1.6 feet). The connector is a miniature coaxial ClickLoc connector with standard cable. The nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.45 ± 0.50 Ω for the 0.5 meter length. The probe is designed to seal differential pressure between the probe tip and case using a Viton O-ring.

Industry Applications

This proximity probe is ideal for monitoring shaft vibration and position in steam turbines, gas turbines, centrifugal compressors, and large pumps. The 8 mm sensor size and PPS tip provide reliable gap measurements even in oil mist or high-temperature environments. The armored cable protects against abrasion during installation and operation, reducing downtime risks.

Installation & Setup Guidance

Mount the 330104-00-12-05-02-00 using the M10 x 1 thread into a properly tapped hole. Ensure the probe tip is clean and free of debris before installation. Gap the probe at 1.27 mm (50 mils) for optimal linear range when used with a 3300 XL Proximitor Sensor and extension cable. Verify the target material is AISI 4140 steel for system accuracy and interchangeability. Use the miniature coaxial ClickLoc connector for secure, quick cable attachment.

Maintenance & Reliability

Periodically inspect the probe cable and connector for wear or damage. The Viton O-ring seal should be checked during routine maintenance to ensure differential pressure integrity. The stainless steel case resists corrosion in most industrial environments. For best reliability, operate the system within the specified power supply range of -17.5 Vdc to -26 Vdc (or -23 Vdc to -26 Vdc with barriers) and maintain a 10 kΩ load.

Selection Guide & Purchasing Advice

Before ordering, confirm your system requires a 3300 XL 8 mm probe with M10 x 1 thread and 0.5 meter cable. Verify compatibility with your existing 3300 XL Proximitor Sensor and extension cable.
