330104-00-04-10-02-05 Bently Nevada Proximity Probe

Product Overview

The Bently Nevada 330104-00-04-10-02-05 is a high-precision 3300 XL 8 mm Proximity Probe designed for critical industrial machinery monitoring. Engineered and manufactured in the U.S.A., this eddy current sensor provides exceptional accuracy in measuring vibration and position. It is built to operate reliably in harsh environments, featuring a PPS tip and stainless steel housing that maintains performance integrity even under high differential pressure and extreme temperatures.

Core Technical Advantages

Superior Mechanical Durability

The probe tip is constructed from Polyphenylene Sulfide (PPS) and reinforced with a Viton® O-ring, allowing the unit to withstand differential pressures up to 20 bar. The AISI 303/304 Stainless Steel case ensures long-term corrosion resistance in demanding chemical or offshore applications.

Precision Electrical Performance

Designed for zero-drift stability (less than 0.05% over 1000 hours), the sensor offers a linearity deviation of only ±0.5%. The 50 Ω output resistance and optimized supply sensitivity ensure clean signal transmission to the Proximitor® Sensor even over extended cable runs.

Global Compliance & Safety

This probe is fully certified for hazardous locations with ATEX, IECEx, and CSA approvals. It meets Class I, II, and III Division 1 requirements, ensuring safe operation in Zone 0 and Zone 1 explosive atmospheres.

Technical Specifications

Engineering Installation Notes

• Gap Calibration: The probe is optimized for a 1.27 mm (50 mils) static gap setting for linear displacement measurements.
• Connector Protection: The miniature coaxial ClickLoc connector is IP67-rated. Always ensure the connector is dry and free of debris before mating.
• Mounting Torque: Avoid over-tightening the M10 threads; use a calibrated torque wrench to ensure the stainless steel case is not deformed during installation.

Technical FAQs

Q1: Can this probe be used with non-steel targets?

A1: While factory-calibrated for AISI 4140 steel, it can measure other conductive materials. However, a custom scale factor will be required to maintain accuracy.

Q2: What is the maximum temperature the probe tip can handle?

A2: The stainless steel housing and PPS tip are designed for high-heat industrial environments, maintaining structural integrity up to 400°C for the housing.

Q3: How does the ClickLoc connector benefit field maintenance?

A3: The ClickLoc system provides an audible click when fully seated and features a specialized seal to prevent oil or moisture ingress, which is the most common cause of signal failure.
