Bently Nevada 330104-00-06-50-01-00 3300 XL 8 mm Proximity Probe

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330104-00-06-50-01-00 3300 XL 8 mm proximity probe delivers precise displacement measurements. This metric probe features a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, built for harsh environments. Part of the trusted 3300 XL series, it provides a linear range of 2 mm (80 mils) starting at approximately 0.25 mm from the target, with a recommended gap setting of -9 Vdc for radial vibration applications.

Technical Specifications

The 330104-00-06-50-01-00 offers a 5.0-meter total cable length with a miniature coaxial ClickLoc connector and connector protector. Its nominal probe DC resistance (RPROBE) is 8.73 ± 0.50 ohms from center conductor to outer conductor. The probe case thread is M10x1 with a maximum thread engagement length of 15 mm. Operating temperature range for the standard probe is -52°C to +177°C (-62°F to +350°F). An extended temperature range version supports probe tip temperatures up to +218°C and cable temperatures up to +260°C.

Industry Applications

This proximity probe excels in radial vibration monitoring of rotating machinery such as turbines, compressors, and pumps. The 5-meter probe is designed for use with the 5-meter Proximitor sensor only, ensuring matched performance. Its robust construction withstands high humidity, with less than a 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68-2-3. For hazardous areas, the probe can be installed with intrinsically safe zener barriers or galvanic isolators for Class I, Zone 0 and Class I, Division 2 environments.

Installation Guidance

Field wiring requires 0.2 to 1.5 mm² (16 to 24 AWG) conductor, preferably using a 3-conductor shielded triad cable with tinned wiring. Maximum field wiring length between the Proximitor sensor and monitor is 305 meters (1,000 feet). The probe is designed to seal differential pressure between tip and case using a Viton O-ring; note that probes are not pressure tested prior to shipment. For applications requiring pressure seal verification, contact the custom design department.

Maintenance and Reliability

Routine inspection of the probe cable and connector ensures reliable signal transmission. Avoid exposing the probe to temperatures below –34°C (–30°F) to prevent premature failure of the pressure seal. The PPS tip resists chemical attack, while the stainless steel case provides corrosion resistance. For extended life, verify compatibility with the target material and operating environment.

Buying Guide

When ordering the 330104-00-06-50-01-00, confirm the required cable length and connector type. This model includes the miniature coaxial ClickLoc connector with protector. For replacement or new installations, ensure the Proximitor sensor matches the 5-meter probe length. plcmatrix.com offers this Bently Nevada probe along with expert support to verify compatibility with your monitoring system.
