Product Overview
With a temperature range from -51°C to +177°C and a 5/8-18 UNF thread, the Bently Nevada 330707-00-62-10-12-00 3300 XL 11 mm Proximity Probe delivers reliable proximity sensing in demanding industrial environments. Designed for precision vibration monitoring, this probe uses a Polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case to resist chemical attack and mechanical wear. The 75 ohm triaxial cable with FEP insulation ensures signal integrity even in harsh conditions.

Industry Applications
The Bently Nevada 330707-00-62-10-12-00 is ideal for measuring shaft vibration and displacement in rotating machinery such as steam turbines, centrifugal compressors, and large pumps. Its wide temperature tolerance makes it suitable for engine and gearbox monitoring in power generation and oil & gas applications. The robust PPS tip and stainless steel case prevent common failure modes like tip breakage and corrosion, ensuring long-term measurement accuracy.
Installation and Setup
Proper installation of the Bently Nevada 330707-00-62-10-12-00 begins with verifying thread compatibility (5/8-18 UNF) and thread engagement depth (max 0.938 in). Use the recommended torque of 15.2 N·m for the probe case to avoid thread galling. For the connector, tighten only finger-tight (max 0.565 N·m) to avoid damaging the miniature coaxial ClickLoc connector. Observe the minimum bend radius of 25.4 mm (1.0 in) for the FluidLoc cable to prevent internal conductor stress.
Maintenance and Reliability
The Bently Nevada 330707-00-62-10-12-00 uses a Viton O-ring to seal differential pressure between the probe tip and case. While the probe can operate from -51°C to +177°C, exposure below -34°C may cause premature seal failure — avoid sustained low temperatures. Inspect the cable and connector periodically for signs of wear or kinking. The FEP insulation and 304 SS case provide excellent resistance to industrial contaminants, reducing the need for frequent replacements.
Selection Guide
When ordering the Bently Nevada 330707-00-62-10-12-00, confirm the unthreaded length (0.0 in), overall case length (6.2 in), and total probe length (1.0 meter). This variant has a miniature coaxial ClickLoc connector with FluidLoc cable and no agency approvals required. For other configurations, contact UBEST Automation at ubest101 for expert guidance.
