Bently Nevada 330104-00-02-20-01-05 3300 XL 8 mm Proximity Probe

Product Overview

When unplanned downtime threatens production targets, the Bently Nevada 330104-00-02-20-01-05 3300 XL 8 mm proximity probe delivers the precise measurement needed to keep rotating machinery running efficiently. This probe is part of the proven 3300 XL series, engineered for non-contact vibration and position sensing in harsh industrial environments. With its robust construction and agency approvals, it reduces the risk of costly failures by providing accurate, real-time data.

Technical Specifications

The 330104-00-02-20-01-05 features a polyphenylene sulfide (PPS) probe tip and an AISI 303 or 304 stainless steel case, ensuring durability in demanding conditions. It offers an unthreaded length of 00 mm and an overall case length of 20 mm. The total cable length is 2.0 meters (6.6 feet), equipped with a miniature coaxial ClickLoc connector and FluidLoc cable for reliable signal transmission. The connector includes a protector, and the cable is standard. Nominal probe DC resistance is 7.88 ± 0.50 ohms for the 2.0 m length. Agency approvals include CSA, ATEX, and IECEx, supporting global installation requirements.

Industry Applications

This proximity probe is ideal for monitoring vibration and shaft position in turbines, compressors, pumps, and motors. In a petrochemical plant, for example, the 330104-00-02-20-01-05 helps detect early signs of bearing wear or imbalance, allowing maintenance teams to schedule repairs during planned outages instead of facing emergency shutdowns. By catching issues early, facilities reduce repair costs and extend equipment life, directly improving return on investment.

Installation Guidance

Proper installation ensures optimal performance. The probe uses an M10 x 1 thread for secure mounting. Before installation, verify that the target material matches the AISI 4140 steel target used for system calibration, as accuracy specifications apply only to such targets. Gap the probe at 1.27 mm (50 mils) for standard operation. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring, so avoid overtightening to maintain seal integrity.

Maintenance & Reliability

Routine inspection of the probe and cable assembly helps prevent unexpected failures. Check the connector and cable for wear or damage, especially in high-vibration areas. The stainless steel case resists corrosion, but periodic cleaning with a soft cloth is recommended. Following manufacturer guidelines for periodic testing ensures the probe continues to deliver accurate readings, minimizing the total cost of ownership by extending service intervals.

Selection & Purchasing Advice

When ordering the 330104-00-02-20-01-05, confirm that the cable length and connector type match your system requirements. The miniature coaxial ClickLoc connector with protector is suited for tight spaces.
