Bently Nevada 330104-01-14-10-01-CN 3300 XL 8 mm Proximity Probe

Product Introduction

When unexpected machine vibration threatens production uptime, the Bently Nevada 330104-01-14-10-01-CN 3300 XL 8 mm Proximity Probe provides precise, non-contact displacement measurements. This probe is part of the trusted 3300 XL series, designed for continuous monitoring of shaft vibration and position in critical rotating equipment such as turbines, compressors, and pumps. Manufactured in the USA, it offers robust construction with a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, ensuring long-term reliability in harsh industrial environments.

Technical Specifications Breakdown

The 330104-01-14-10-01-CN features an unthreaded length of 01 mm and an overall case length of 14 mm, with a total length option of 1.0 meter (3.3 feet). It uses a miniature coaxial ClickLoc connector with connector protector and standard cable. The probe tip material is polyphenylene sulfide (PPS), and the case material is AISI 303 or 304 stainless steel. Nominal probe DC resistance is 7.59 ± 0.50 Ω for the 1.0 m length. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Electrical specifications include a power requirement of -17.5 Vdc to -26 Vdc at 12 mA maximum consumption, with supply sensitivity less than 2 mV change per volt change in input voltage, and output resistance of 50 Ω.

Industry Applications

This proximity probe excels in vibration monitoring for steam turbines, centrifugal compressors, and large pumps. In a typical power generation plant, the 330104-01-14-10-01-CN mounts near bearing housings to detect shaft radial vibration and axial position. Its 8 mm sensing face and PPS tip resist oil and moisture, making it suitable for continuous operation in lubricated environments. The probe's M10 x 1 thread simplifies installation into standard mounting brackets, reducing retrofit time.

Installation & Setup Guidance

For optimal performance, mount the probe with a gap of 1.27 mm (50 mils) to an AISI 4140 steel target. Ensure the probe tip is clean and free of debris before installation. Use the included ClickLoc connector to secure the extension cable, and verify that the cable routing avoids sharp bends or contact with hot surfaces. The probe seals differential pressure via its Viton O-ring, so confirm the mounting hole is properly sized to maintain seal integrity.

Maintenance & Reliability

Routine inspection of the probe tip and cable connector prevents signal degradation. Check for physical damage or contamination on the PPS tip, and verify the O-ring seal remains intact. The stainless steel case resists corrosion, but periodic cleaning with a mild solvent is recommended. For systems operating near maximum temperature, monitor the probe resistance periodically to ensure it stays within 7.59 ± 0.50 Ω. Following these steps extends service life and reduces unplanned downtime.

Compatibility & Integration

The 330104-01-14-10-01-CN accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm proximity probe and extension cable. It integrates seamlessly with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. For non-incendive installations, power requirements range from -17.5 Vdc to -26 Vdc; with barriers, use -23 Vdc to -26 Vdc. Verify the system load is 10 kΩ for accurate output. This probe is a direct replacement for earlier 3300-series probes in existing Bently Nevada racks.
