Bently Nevada 330104-02-08-10-01-00 3300 XL 8 mm Proximity Probe, Metric

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330104-02-08-10-01-00 provides reliable measurement. This 3300 XL 8 mm proximity probe, part of the trusted Bently Nevada series, offers precise displacement sensing for critical rotating equipment. Designed with a PPS tip and stainless steel case, it withstands harsh industrial environments.

Technical Specifications

The 330104-02-08-10-01-00 features a 2 mm linear range starting at approximately 0.25 mm from the target, extending to 2.3 mm. Recommended gap setting for radial vibration is -9 Vdc, roughly 1.27 mm. Nominal probe DC resistance measures 7.59 ± 0.50 ohms for the 1.0 meter length. The probe case thread is M10x1 with a maximum thread engagement of 15 mm. Operating temperature range spans -52°C to +177°C for standard probes, with extended range options for the tip up to +218°C and cable up to +260°C. Relative humidity testing shows less than 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3.

Industry Applications

This probe excels in monitoring radial vibration and axial position of turbines, compressors, pumps, and motors. Its robust construction suits oil and gas, power generation, and petrochemical facilities where continuous operation is essential. The armored design and miniature coaxial ClickLoc connector simplify installation in tight spaces.

Installation Guidance

Field wiring accepts 0.2 to 1.5 mm² (16 to 24 AWG) conductors. Use a 3-conductor shielded triad cable with tinned ends. Maximum field wiring length between the probe and monitor is 305 meters (1,000 feet). For optimal signal integrity, refer to frequency response graphs for rolloff at high frequencies with longer runs. Ensure the probe tip material (polyphenylene sulfide) is compatible with the target environment.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The Viton O-ring seals differential pressure between tip and case, but probes are not pressure tested before shipment. Contact Bently Nevada custom design for pressure test requirements.

Compatibility & Integration

The 330104-02-08-10-01-00 integrates with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators for Class I, Zone 0 environments. For non-incendive circuits, follow drawing 140979 for Class I, Zone 2 applications.

Selection & Purchasing Advice

Before ordering, verify the unthreaded length (20 mm), overall case length (80 mm), total length (1.0 meter), and connector type (miniature coaxial ClickLoc with protector). The agency approval option is not required for this configuration. For current availability and lifecycle status, contact plcmatrix.com, a trusted supplier of industrial automation components.
