Industry Applications
Use it for radial vibration and thrust position monitoring on steam turbines, centrifugal compressors, and large pumps. The 2 mm linear range and -9 Vdc recommended gap setting ensure accurate data for predictive maintenance programs. The PPS tip resists wear in high-speed applications, reducing false alarms.
Installation & Setup Guidance
Mount the probe with the M10 x 1 thread, ensuring maximum thread engagement of 15 mm. Use 3-conductor shielded triad cable (16 to 24 AWG) for field wiring. Keep the distance between the 3300 XL Proximitor Sensor and the monitor within 305 meters (1,000 feet) to avoid signal roll-off. Set the initial gap to approximately 1.27 mm (50 mils) for radial vibration measurements.
Maintenance & Reliability
Inspect the probe tip and cable periodically for physical damage or contamination. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The stainless steel case and Viton O-ring provide robust sealing against differential pressure, though probes are not pressure tested before shipment.
Compatibility & Integration
This probe works with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga requirements. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc.
Selection Guide & Purchasing Advice
Choose the 330103-02-10-05-02-CN for metric installations requiring a 0.5 m cable and ClickLoc connector. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
