Bently Nevada 330104-00-07-10-02-CN 3300 XL 8 mm Proximity Probe, Metric

Product Introduction

As industrial machinery evolves toward higher speeds and tighter tolerances, the need for precise vibration monitoring has never been greater. The Bently Nevada 330104-00-07-10-02-CN is a 3300 XL 8 mm proximity probe designed to meet these demands. This metric probe features an M10x1 thread, a 1.0 meter cable, and a miniature coaxial ClickLoc connector. It provides accurate shaft displacement measurements in rotating equipment, helping operators detect early signs of mechanical faults.

Technical Specifications Breakdown

The 330104-00-07-10-02-CN offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to about 1.27 mm (50 mils). Its nominal DC resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms for the 1.0 meter probe length. The probe tip material is polyphenylene sulfide (PPS), and the case is made of AISI 303 or 304 stainless steel. The operating and storage temperature range for the standard probe is -52°C to +177°C (-62°F to +350°F).

Industry Applications

This proximity probe is ideal for monitoring radial vibration and axial position in turbines, compressors, pumps, and motors. In a typical steam turbine installation, the 330104-00-07-10-02-CN provides continuous shaft displacement data, enabling predictive maintenance strategies that reduce unplanned downtime. Its robust stainless steel case and PPS tip withstand harsh environments, making it suitable for oil and gas, power generation, and chemical processing facilities.

Installation & Setup Guidance

For proper installation, use 3-conductor shielded triad cable with tinned field wiring. The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). The probe case thread is M10x1, with a maximum thread engagement of 15 mm. Ensure the probe is mounted securely and the gap is set to -9 Vdc for radial vibration measurements. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal.

Maintenance & Reliability

Regular inspection of the probe and cable is recommended to ensure reliable operation. The probe sealing material includes a Viton O-ring designed to seal differential pressure between the tip and case. While probes are not pressure tested before shipment, the design ensures long-term stability in typical industrial environments. The probe relative humidity specification shows less than a 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC standard 68-2-3 for up to 56 days, indicating excellent moisture resistance.
