Product Overview
The Bently Nevada 330709-000-230-90-01-00 3300 XL 11 mm Proximity Probes deliver precise shaft vibration and position measurements in rotating machinery. Built for harsh environments, this probe resists common failure modes such as temperature-induced pressure seal damage and connector loosening. The 330709-000-230-90-01-00 design includes a rugged M16x1.5 thread, a 9.0-meter coaxial cable with ClickLoc connector, and a polyphenylene sulfide (PPS) tip for reliable performance in demanding applications.

Failure Mode Analysis & Robust Design
The 330709-000-230-90-01-00 addresses common failure causes in proximity probes. Its PPS tip resists chemical attack and high temperatures, while the stainless steel case withstands corrosion. The probe’s temperature schedule covers classifications T1 to T5, with ambient ranges from -55°C up to +232°C, preventing premature seal failure. The recommended torque values (21.1 N•m for the case, finger-tight for the connector) help avoid thread damage or loose connections that can cause false readings. Cross-talk is minimized by adhering to the specified minimum target and shaft diameters.
Industry Applications
This probe is ideal for monitoring critical rotating equipment such as steam turbines, compressors, and pumps. In a petrochemical plant, the 330709-000-230-90-01-00 provides accurate shaft displacement data, enabling early detection of bearing wear or imbalance. For power generation, its wide temperature range allows installation near hot turbine casings without signal degradation. The 9.0-meter cable length suits large machinery where the monitor rack is positioned remotely.
Installation & Setup Guidance
Mount the Bently Nevada 330709-000-230-90-01-00 with the recommended torque to avoid thread stress. Use a torque wrench set to 21.1 N•m for the M16x1.5 case. For the miniature coaxial ClickLoc connector, tighten by hand only; overtightening (max 0.565 N•m) can damage the contact. Ensure the probe tip is perpendicular to the target surface and that the minimum flat surface diameter of 30.5 mm is met. Observe the minimum bend radius of 25.4 mm (1.0 in) for the cable to prevent internal breakage.
Maintenance & Reliability
Inspect the probe cable and connector for wear or moisture ingress annually. The PPS tip requires no routine cleaning but should be protected from abrasive particles. The probe’s robust construction – 304 SST case and FEP-insulated cable – offers long service life in temperatures from -52°C to +177°C. Note: Exposing the probe to temperatures below -34°C may risk the pressure seal, so avoid prolonged sub-30°F storage without proper conditioning.
Selection Guide & Purchasing Advice
When ordering the 330709-000-230-90-01-00, confirm compatibility with your monitor system (e.g., 3300 XL series). The 9.0-meter cable length is fixed; for different lengths, consider other part numbers in the 330709 family. UBEST Automation stocks genuine Bently Nevada probes with full traceability.
