Bently Nevada 330103-00-19-10-12-CN 3300 XL 8 mm Proximity Probe

Overview of the 3300 XL 8 mm Proximity Probe

The Bently Nevada 330103-00-19-10-12-CN is a 3300 XL 8 mm proximity probe designed for precise shaft vibration and position measurements in industrial rotating machinery. This model features an M10 x 1 thread, a 190 mm overall case length, and a 1.0 meter (3.3 feet) total length with a miniature coaxial ClickLoc connector and FluidLoc cable. The probe tip is made of polyphenylene sulfide (PPS) for durability, and the case is AISI 303 or 304 stainless steel. With a linear range of 2 mm (80 mils) and a recommended gap setting of -9 Vdc (approximately 1.27 mm), it provides accurate, reliable data for predictive maintenance and machine protection.

Technical Specifications Breakdown

Key parameters for the 330103-00-19-10-12-CN are listed below for quick reference:

Industry Applications

Its 2 mm linear range and -9 Vdc gap setting provide high-resolution data for early fault detection. In petrochemical plants, the probe’s PPS tip and stainless steel case resist harsh environments. For power generation, the wide temperature range (-52°C to +177°C) ensures reliable operation near hot bearings. Compared to lower-cost eddy current probes, the 330103-00-19-10-12-CN offers superior accuracy and long-term stability, reducing unplanned downtime.

Installation and Setup Guidance

Mount the probe using the M10 x 1 thread with a maximum engagement of 15 mm. Use 3-conductor shielded triad cable (16 to 24 AWG) for field wiring, with a maximum length of 305 meters (1,000 feet) to the Proximitor Sensor. Set the gap to approximately -9 Vdc (1.27 mm) for radial vibration measurements. Ensure the target surface is clean and free of magnetic irregularities. For extended temperature applications, verify cable and connector ratings.

Maintenance and Reliability

Inspect the probe cable and connector periodically for damage, especially in high-vibration areas. The probe is designed to seal differential pressure between tip and case using a Viton O-ring. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe’s relative humidity tolerance (less than 3% ASF change at 93% humidity per IEC 68-2-3) ensures stable performance in humid environments.

Compatibility and Integration

The 330103-00-19-10-12-CN integrates with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators (Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga). For non-incendive circuits, connect per drawing 140979 (Class I, Zone 2: AEx/Ex nA IIC T5...T1 Gc). Verify agency approvals for your region.

Selection Guide and Purchasing Advice

When selecting a 3300 XL probe, consider the thread size, cable length, and connector type. The 330103-00-19-10-12-CN is suited for standard applications with a 1.0 m cable and ClickLoc connector. For longer cable runs or armored versions, consult other part numbers. AutoDCSTech stocks this probe and can assist with lifecycle status and availability.
