Bently Nevada 330104-00-08-10-01-05 3300 XL 8 mm Proximity Probe

Reliable Vibration Monitoring for Critical Machinery

When unplanned downtime threatens production targets, the Bently Nevada 330104-00-08-10-01-05 3300 XL 8 mm Proximity Probe delivers the precise shaft displacement data needed to protect rotating assets. This probe is designed for continuous operation in harsh industrial environments, offering a robust armored construction and a miniature coaxial ClickLoc connector with connector protector for secure signal transmission.

Key Technical Specifications

The 330104-00-08-10-01-05 features a nominal probe DC resistance of 7.59 ± 0.50 Ω (for 1.0 meter length) measured from center conductor to outer conductor. Its probe tip is made of Polyphenylene sulfide (PPS), while the probe case is constructed from AISI 303 or 304 stainless steel (SST). The probe is designed to seal differential pressure between the tip and case using a Viton® O-ring. It carries agency approvals: CSA, ATEX, and IECEx.

Real-World Applications

In a steam turbine train, the 330104-00-08-10-01-05 provides critical shaft vibration and position feedback to the protection system. Its 8 mm sensing tip and 1.0 meter (3.3 feet) total length allow installation in tight bearing housing clearances. The M10 x 1 thread and armor option simplify mounting in high-vibration zones, reducing signal noise and improving data integrity.

Installation Guidance

Proper installation begins with verifying the probe's unthreaded length (00 mm) and overall case length (80 mm). Use the miniature coaxial ClickLoc connector for quick, reliable cable attachment. Ensure the probe is gapped at 1.27 mm (50 mils) when used with a 3300 XL 8 mm Proximitor Sensor and extension cable for optimal linear range. Always follow the manufacturer's mounting torque specifications to avoid damaging the PPS tip.

Maintenance and Reliability

The stainless steel case and PPS tip resist corrosion and wear, extending service life in demanding environments. Periodically inspect the probe cable and connector for damage. The Viton® O-ring seal maintains differential pressure integrity, so avoid exposing the probe to chemicals that may degrade Viton®. Routine verification of probe DC resistance helps detect early degradation.

Compatibility and Integration

This probe is part of the 3300 XL 8 mm system and accepts 3300-series 5 mm and 3300 XL 8 mm proximity probes and extension cables. It requires a -17.5 Vdc to -26 Vdc power supply (with nonincendive circuit) and delivers a 50 Ω output resistance. For best performance, pair with Bently Nevada 3300 XL Proximitor Sensors and extension cables.

Purchasing Advice

Before ordering, confirm your system requirements: probe length (1.0 m), thread type (M10 x 1), and agency approval needs (CSA, ATEX, IECEx).
