Bently Nevada 330104-10-16-10-12-00 3300 XL 8 mm Proximity Probe

Product Overview

When critical rotating machinery experiences unexpected vibration, the Bently Nevada 330104-10-16-10-12-00 provides precise, non-contact measurement to protect your assets. This 3300 XL 8 mm proximity probe is part of the trusted 3300 XL series, designed for reliable shaft vibration and position monitoring in demanding industrial environments. Manufactured in the U.S.A., this probe offers a robust solution for continuous condition monitoring.

Technical Specifications

The 330104-10-16-10-12-00 features an 8 mm diameter sensing tip made of polyphenylene sulfide (PPS) for durability and chemical resistance. The probe case is constructed from AISI 303 or 304 stainless steel (SST), ensuring corrosion resistance in harsh settings. Key dimensional options include an unthreaded length of 100 mm, overall case length of 160 mm, and a total length of 1.0 meter (3.3 feet). The connector is a miniature coaxial ClickLoc type with FluidLoc cable, providing secure and reliable signal transmission. Nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.59 ± 0.50 ohms for the 1.0 m probe length. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications

This proximity probe is ideal for monitoring radial vibration and axial position in turbines, compressors, pumps, and other rotating equipment. In power generation, it helps detect early signs of bearing wear or imbalance, reducing unplanned downtime. In oil and gas applications, the robust stainless steel and PPS construction withstands corrosive atmospheres and high temperatures up to +232°C (for T1 classification). The 330104-10-16-10-12-00 integrates seamlessly with Bently Nevada 3300 XL Proximitor sensors and extension cables to form a complete measurement system.

Installation & Setup Guidance

For optimal performance, mount the probe perpendicular to the target shaft surface at a nominal gap of 1.27 mm (50 mils) when using an AISI 4140 steel target. Ensure the probe tip is clean and free from debris before installation. Use the ClickLoc connector to secure the cable, and route the FluidLoc cable away from high-voltage sources to avoid electrical interference. Verify the power supply meets the requirement of -17.5 Vdc to -26 Vdc for non-incendive circuits, or -23 Vdc to -26 Vdc when using barriers. Refer to installation drawing 140979 for non-incendive connections or drawing 141092 for intrinsically safe setups.

Maintenance & Reliability

Regularly inspect the probe tip and cable for physical damage or contamination. The PPS tip resists many chemicals, but avoid prolonged exposure to strong acids or bases. Check the Viton O-ring seal integrity during routine maintenance to ensure pressure sealing. The stainless steel case provides excellent corrosion resistance, but periodic visual checks are recommended in extreme environments. For hazardous locations, follow the temperature schedule: for EPL Ga and Gc, ambient temperature ranges from -55°C to +232°C (T1) down to -55°C to +40°C (T5). Always verify the probe's lifecycle status and availability with plcmatrix.com before ordering.

Compatibility & Integration

The 330104-10-16-10-12-00 is designed for use with Bently Nevada 3300 XL Proximitor sensors and extension cables. It accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm probe and extension cable. The system accuracy and interchangeability specifications are based on an AISI 4140 steel target; using other targets may require recalibration. For hazardous area installations, the probe supports Class I, Zone 0 (AEx/Ex ia IIC T5...T1 Ga) with intrinsic safety barriers, and Class I, Zone 2 (AEx/Ex nA IIC T5...T1 Gc) with non-incendive circuits.

Selection Guide & Purchasing Advice

When selecting the 330104-10-16-10-12-00, verify the cable length (1.0 m), connector type (miniature coaxial ClickLoc), and agency approval option (00 = not required). Ensure your target material is compatible; the system is calibrated for AISI 4140 steel. For replacement or upgrade projects, confirm the existing Proximitor sensor and extension cable are 3300 XL series components.
