Bently Nevada 330104-00-24-10-02-00 3300 XL 8 mm Proximity Probe

Product Introduction

When machinery vibration threatens uptime and safety, the Bently Nevada 330104-00-24-10-02-00 provides reliable, non-contact displacement measurement. This 3300 XL 8 mm proximity probe is designed for permanent installation in critical rotating equipment such as steam turbines, compressors, and pumps. Its robust construction and proven eddy-current sensing technology deliver accurate shaft position and vibration data, enabling predictive maintenance and reducing unplanned downtime.

Technical Specifications Breakdown

The 330104-00-24-10-02-00 features a polyphenylene sulfide (PPS) probe tip and an AISI 303 or 304 stainless steel case for durability in harsh environments. The probe has an unthreaded length of 00 mm, an overall case length of 240 mm, and a total length of 1.0 meter (3.3 feet). It uses a miniature coaxial ClickLoc connector with standard cable. The nominal probe DC resistance from center conductor to outer conductor is 7.59 ± 0.50 Ω at 1.0 m length. The probe is designed to seal differential pressure between the probe tip and case using a Viton O-ring. It accepts a 3300-series 5 mm or 3300 XL 8 mm probe and extension cable, requires -17.5 Vdc to -26 Vdc power with 12 mA maximum consumption, and has an output resistance of 50 Ω.

Industry Applications

This proximity probe is ideal for monitoring radial vibration and axial position in turbomachinery. In a steam turbine application, the 330104-00-24-10-02-00 mounts near the bearing to detect shaft displacement changes that indicate imbalance or misalignment. In a centrifugal compressor, it provides real-time data for surge protection and performance optimization. The probe's armored construction and wide temperature range (-55°C to +232°C for T1 classification) make it suitable for both indoor and outdoor installations in oil and gas, power generation, and petrochemical plants.

Installation & Setup Guidance

For accurate measurements, mount the probe perpendicular to the target surface with a gap of 1.27 mm (50 mils) when using an AISI 4140 steel target. Ensure the probe tip is clean and free of debris before installation. Use the M10 x 1 thread for secure mounting. Connect the miniature coaxial ClickLoc connector to the extension cable, then route the cable away from high‑interference sources. Verify power supply voltage between -17.5 Vdc and -26 Vdc. For intrinsically safe installations, follow drawing 141092; for nonincendive circuits, use drawing 140979.

Maintenance & Reliability

Regularly inspect the probe tip and cable for physical damage or contamination. The PPS tip resists chemical attack, but periodic cleaning with a soft, dry cloth is recommended. Check the O-ring seal integrity during routine maintenance to ensure pressure sealing. The probe's stainless steel case withstands corrosion in most industrial environments. For maximum reliability, verify the system calibration annually using an AISI 4140 steel target. The 330104-00-24-10-02-00 is designed for long service life, reducing total cost of ownership through fewer replacements and lower downtime.

Buying Guide & Purchasing Advice

Before ordering, confirm that the 330104-00-24-10-02-00 matches your system requirements: 8 mm probe size, 240 mm case length, 1.0 m cable, and ClickLoc connector. Ensure compatibility with your existing 3300 XL or 3300-series monitor. For replacement or upgrade, verify the target material and gap settings. plcmatrix.com stocks this Bently Nevada probe and can advise on availability, lead times, and compatible accessories.
