Bently Nevada 330104-14-19-10-11-CN 3300 XL 8 mm Proximity Probe

Product Introduction

In the demanding world of industrial rotating machinery, precise vibration and position monitoring is critical to prevent costly downtime and catastrophic failures. The Bently Nevada 330104-14-19-10-11-CN, a 3300 XL 8 mm proximity probe, delivers the accuracy and durability required for these challenging environments. Part of the trusted 3300 XL series, this probe is designed for non-contact displacement measurements, providing essential data for machinery protection and condition monitoring.

Technical Specifications Breakdown

The 330104-14-19-10-11-CN features an M10 x 1 thread and includes armor for enhanced cable protection. It offers an unthreaded length of 14 mm and an overall case length of 19 mm. The total length option is 1.0 meter (3.3 feet), with a miniature coaxial ClickLoc connector and FluidLoc cable. The connector includes a protector, and the probe carries a Country Specific Approval (CN). The probe tip is made of Polyphenylene sulfide (PPS), and the case is constructed from AISI 303 or 304 stainless steel. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. For a 1.0-meter probe, the nominal DC resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms.

Industry Applications

This proximity probe is widely used in critical rotating equipment such as steam turbines, compressors, pumps, and electric motors. In a typical steam turbine application, the 330104-14-19-10-11-CN monitors shaft vibration and axial position, feeding data to a Bently Nevada monitoring system. This enables early detection of bearing wear or imbalance, allowing maintenance teams to plan interventions before unplanned shutdowns occur. The probe's robust construction and precise performance make it a reliable choice for continuous operation in harsh industrial environments.

Installation & Setup Guidance

Proper installation is key to achieving accurate measurements. When mounting the 330104-14-19-10-11-CN, ensure the probe tip is correctly gapped at 1.27 mm (50 mils) against an AISI 4140 steel target for optimal performance. The probe must be connected to a compatible 3300 XL 8 mm Proximitor Sensor and extension cable. Verify that the power supply meets the requirements of -17.5 Vdc to -26 Vdc when installed with a non-incendive circuit, and -23 Vdc to -26 Vdc with barriers. Always follow the installation drawing 140979 for proper wiring and grounding to maintain system accuracy and safety.

Maintenance & Reliability

Routine inspection of the probe and cable assembly is recommended to ensure long-term reliability. Check for any signs of physical damage or wear on the PPS tip and stainless steel case. The Viton O-ring seal should be verified periodically to maintain differential pressure integrity. Because the probe is designed for continuous operation, regular calibration checks against a known target help sustain measurement accuracy. By following these simple maintenance steps, users can maximize the service life of the 330104-14-19-10-11-CN and reduce total cost of ownership.

Selection Guide & Purchasing Advice

Before purchasing the 330104-14-19-10-11-CN, confirm that your system uses 3300 XL 8 mm components for full compatibility. Verify the required cable length and connector type—this model includes a 1.0-meter FluidLoc cable with a miniature coaxial ClickLoc connector and protector.
