Performance & Reliability
The 330904-00-15-10-01-00 excels in environments where chemical resistance is critical. Its PPS probe tip and stainless steel case withstand aggressive media, making it ideal for process compressors and similar applications. The probe's side-view characteristics outperform the 3000-series 190 probe, ensuring accurate gap measurements even in tight installations.
With an incremental scale factor of 7.87 V/mm and a linear range of 1.5 mm, this probe delivers precise, repeatable readings. The deviation from best fit straight line remains below ±0.06 mm, guaranteeing high measurement fidelity. The probe operates reliably across a wide temperature range, from -52°C to +177°C, and supports field wiring up to 305 meters (1,000 feet) without significant signal degradation.
Installation & Setup
Proper installation is essential for optimal performance. The probe case thread is M8X1, and the recommended installation torque is finger tight, with a maximum of 0.56 N•m (5 in•lb). Ensure the minimum bend radius of 25.4 mm (1.0 in) is respected for the probe cable to prevent damage. For field wiring, use a three-conductor shielded triad cable with conductor sizes from 0.2 to 1.5 mm² (16 to 24 AWG). The maximum distance between the 3300 XL NSv Proximitor Sensor and the monitor is 305 meters (1,000 feet).
When mounting, position the probe so that the target surface is perpendicular to the probe axis. For shaft diameters smaller than 13 mm (0.5 in), expect a change in scale factor; reducing the gap can mitigate this effect. Always verify the gap setting to 1.0 mm (40 mils) for optimal linearity.
Maintenance & Longevity
Routine inspection of the probe cable and connector ensures long service life. The connector-to-connector torque should be maintained within the recommended range: maximum 7.3 N•m (65 in•lb) and recommended 5.1 N•m (45 in•lb) for M8X1 cases. Check for any signs of abrasion or chemical attack on the armor, especially in harsh environments. The probe is designed to seal differential pressure between the tip and case; the Viton O-ring provides the seal. Note that probes are not pressure-tested before shipment; contact the custom design department if pressure testing is required for your application.
Applications
The 330904-00-15-10-01-00 is widely used in:
- Process compressors in chemical and petrochemical plants
- Turbomachinery vibration monitoring
- Axial position measurement on rotating shafts
- General machinery health monitoring
Its enhanced chemical resistance makes it a preferred choice where exposure to aggressive media is a concern. The probe's compatibility with previous 3300 RAM systems allows for straightforward retrofits.
Selection Guide
Before purchasing, verify the probe length and connector options to match your existing system. The 330904-00-15-10-01-00 includes a miniature coaxial ClickLoc connector with a connector protector and standard cable. For specialized requirements, confirm the total length and unthreaded length options.
