Bently Nevada 330104-00-20-10-02-CN 3300 XL 8 mm Proximity Probe

Introduction

When rotating machinery experiences unexpected vibration, the Bently Nevada 330104-00-20-10-02-CN 3300 XL 8 mm proximity probe provides the precise measurement needed to diagnose and prevent failures. Designed for continuous monitoring of shaft vibration and position, this probe is part of the trusted 3300 XL series and delivers reliable performance in demanding industrial environments.

Technical Specifications Breakdown

The 330104-00-20-10-02-CN features a probe tip made of polyphenylene sulfide (PPS), offering excellent chemical resistance and dimensional stability. The probe case is constructed from AISI 303 or 304 stainless steel, ensuring durability in harsh conditions. With an unthreaded length of 00 mm and an overall case length of 200 mm, this probe fits a variety of mounting configurations. The total length option of 1.0 meter (3.3 feet) provides flexibility for installation. The connector option is a miniature coaxial ClickLoc connector with standard cable, ensuring secure and reliable signal transmission. The probe has a nominal DC resistance of 7.59 ± 0.50 ohms at 1.0 meter length. It is designed to seal differential pressure between the probe tip and case using a Viton O-ring.

Industry Applications

This proximity probe is ideal for monitoring critical rotating equipment such as turbines, compressors, pumps, and motors in industries like oil and gas, power generation, and petrochemical. The 330104-00-20-10-02-CN helps detect shaft vibration, eccentricity, and thrust position, enabling early warning of mechanical issues and reducing unplanned downtime.

Installation & Setup Guidance

Proper installation is crucial for accurate measurements. The probe uses an M10 x 1 thread and should be mounted according to the manufacturer's guidelines. Ensure the probe tip is gapped at 1.27 mm (50 mils) for optimal performance. The miniature coaxial ClickLoc connector simplifies cable attachment and provides a secure connection. Verify that the system uses a -24 Vdc power supply with a 10 kΩ load for best results.

Maintenance & Reliability

Regular inspection of the probe tip and cable is recommended to ensure reliable operation. The PPS tip and stainless steel case provide long service life in harsh environments. The Viton O-ring seal helps maintain pressure integrity. For continued accuracy, verify system calibration periodically using an AISI 4140 steel target.

Compatibility & Integration

The 330104-00-20-10-02-CN integrates seamlessly with 3300 XL 8 mm Proximitor Sensors and extension cables. It accepts non-contacting 3300-series 5 mm and 3300 XL 8 mm probes. The system requires a power supply of -17.5 Vdc to -26 Vdc and delivers an output resistance of 50 ohms. For non-incendive installations, follow drawing 140979.
