Product Introduction
When dealing with turbo-machinery vibration monitoring, improper probe performance can lead to false trips or undetected faults. The Bently Nevada 330709-000-080-10-02-05 3300 XL 11 mm Proximity Probe offers robust design to mitigate cross-talk and temperature-induced errors. This probe is factory-configured with a 1.0 meter cable, Miniature coaxial ClickLoc connector, and multiple agency approvals.
Technical Specifications Breakdown
Key parameters of the 330709-000-080-10-02-05 include:
- Probe DC resistance: 5.9 ± 0.5 ohms (center to outer conductor) for 1.0m probe length.
- Cross-talk: recommended minimum target flat surface diameter 30.5 mm, shaft diameter 152 mm.
- Operating temperature range: -52°C to +177°C (storage and operating).
- Probe case torque: recommended 21.1 N·m, maximum 63.3 N·m for M16x1.5 thread.
- Probe tip material: Polyphenylene sulfide (PPS); case: AISI 304 stainless steel.
These specs ensure reliable operation in harsh environments.
Real-World Applications
The Bently Nevada 330709-000-080-10-02-05 is ideal for measuring shaft vibration in turbines, compressors, and pumps. In a typical steam turbine installation, the probe's low cross-talk ensures accurate data even with nearby metallic surfaces. The wide temperature range suits applications from cryogenic to high-temperature zones.
Installation & Setup Guidance
Proper installation is critical for probe accuracy. For the M16x1.5 thread, engage no more than 24 mm of thread length. Tighten the probe case to recommended torque of 21.1 N·m (187 in·lb) not exceeding maximum 63.3 N·m. Use finger-tight for connector-to-connector torque; max 0.565 N·m. Maintain minimum bend radius of 25.4 mm for cable. Never expose probe to temperatures below -34°C to avoid pressure seal failure.
Maintenance & Reliability
Regular inspection of the probe cable and connector is advised. The 75 ohm triaxial FEP cable resists chemicals and high temperatures. Replace probe if resistance deviates from 5.9 ± 0.5 ohms. The stainless steel case offers corrosion resistance. The probe's design reduces downtime, supporting long-term reliability.
Selection Guide & Purchasing Advice
When ordering, verify total length option (1.0 metre) and connector type (ClickLoc). This model is part of the 3300 XL series. For system integration, ensure clearance for minimum shaft diameter of 152 mm. For further assistance, contact UBEST Automation (www.ubest101.myshopify.com) for expert support.
