Bently Nevada 330104-07-14-05-01-00 3300 XL 8 mm Proximity Probe Overview

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330104-07-14-05-01-00 3300 XL 8 mm Proximity Probe delivers precise, non-contact measurements. This probe is part of the proven 3300 XL series, engineered for continuous monitoring of shaft vibration and position in rotating equipment like turbines, compressors, and pumps. Its robust design includes a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, ensuring durability in harsh industrial environments.

Technical Specifications

The 330104-07-14-05-01-00 features an M10 x 1 thread with armor for secure installation. Key mechanical options include a 70 mm unthreaded length, 140 mm overall case length, and a total length of 0.5 meter (1.6 feet). The connector is a miniature coaxial ClickLoc type with a connector protector and standard cable. The probe tip material is polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel. This probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Electrical performance is optimized for use with a 3300 XL 8 mm Proximitor Sensor and extension cable, requiring a -17.5 Vdc to -26 Vdc power supply. Nominal probe DC resistance from center conductor to outer conductor is 7.45 ± 0.50 Ω for the 0.5 meter length.

Industry Applications

Maintenance engineers rely on the 330104-07-14-05-01-00 for critical machinery protection. In steam turbine trains, it monitors radial vibration to detect early bearing wear. In centrifugal compressors, it tracks axial shaft position to prevent thrust bearing failure. The probe's PPS tip resists chemical attack, making it suitable for refinery and petrochemical applications. Its 0.5 meter cable simplifies installation in tight spaces, reducing downtime during sensor replacement.

Installation Guidance

For reliable measurements, mount the probe perpendicular to the target shaft surface. Use the M10 x 1 threaded mounting hole and tighten to manufacturer torque specifications. Ensure the probe gap is set to 1.27 mm (50 mils) for optimal linear range. Route the armored cable away from high-EMI sources and secure it with cable ties. Verify that the Proximitor Sensor power supply is within -17.5 Vdc to -26 Vdc to maintain accuracy.

Maintenance & Reliability

Regularly inspect the probe tip for debris or damage. Check cable integrity for cuts or abrasions, especially near the connector. The Viton O-ring seal should be verified during each overhaul to maintain pressure integrity. Environmental factors like temperature extremes or corrosive atmospheres can affect performance; monitor output voltage drift as an early warning. Periodic recalibration with a known target ensures long-term accuracy.

Compatibility & Integration

This probe works exclusively with 3300 XL 8 mm Proximitor Sensors and extension cables. It is designed for use with Bently Nevada monitoring systems such as the 3500 series. The miniature coaxial ClickLoc connector ensures a secure, noise-free connection. For retrofit applications, verify that existing cables and sensors are 3300 XL 8 mm series to maintain system accuracy.

Buying Guide

Before purchasing, confirm your required unthreaded length, overall case length, and total length. The 330104-07-14-05-01-00 is a specific configuration with 70 mm unthreaded length, 140 mm case length, and 0.5 meter total length. Ensure your system uses M10 x 1 threaded mounting points. For replacement, match the connector type (miniature coaxial ClickLoc). plcmatrix.com stocks this probe and can verify compatibility with your existing monitoring system.
