Bently Nevada 330708-00-24-10-11-05 11 mm Probe

Product Introduction

The Bently Nevada 330708-00-24-10-11-05 delivers precision non-contact displacement measurement as part of the proven 3300 XL platform. This 11 mm proximity probe excels in radial vibration, axial thrust, and speed monitoring for turbines, compressors, and pumps. Its design incorporates a PPS tip and AISI 304 stainless steel case, ensuring long-term reliability in challenging industrial settings. Significantly, this variant offers a FluidLoc cable and connector protector, enhancing moisture resistance and cable retention in demanding environments. Furthermore, the "05" agency approval option confirms multiple certifications, streamlining global procurement and compliance efforts.

Technical Specifications

The 3300 XL 11 mm Proximity Probe utilizes a 75 Ω triaxial cable with FEP insulation, maintaining signal fidelity across its 1.0 metre (3.3 feet) length. The DC resistance from the center conductor to the outer conductor measures 5.9 ± 0.5 ohms, enabling straightforward driver calibration and system integration. Specifically, the probe case features a 5/8-18 UNF thread with a maximum engagement length of 0.938 inches, accommodating standard mounting hardware configurations. Meanwhile, the recommended installation torque is 15.2 N•m (133 in•lb), with a maximum rated torque of 45.2 N•m (400 in•lb) to prevent over-tightening damage. For the connector interface, finger-tight torque is sufficient, while the absolute maximum is 0.565 N•m (5 in•lb). Additionally, the FluidLoc cable technology provides superior strain relief and environmental sealing, while the ClickLoc connector with protector ensures secure, vibration-resistant connections.

Mechanical and Environmental Ratings

This probe withstands extreme operating and storage temperatures from -51°C to +177°C (-60°F to +351°F). However, exposing the probe to temperatures below -34°C (30°F) may accelerate Viton O-ring seal degradation, so consider this for cold-start applications. The cable exhibits a minimum bend radius of 25.4 mm (1.0 inch), allowing flexible routing even without armor. Moreover, the PPS tip delivers excellent chemical and wear resistance, while the AISI 304 SST case provides robust corrosion protection. The multiple agency approvals (option "05") include certifications for various international standards, simplifying adoption in regulated industries worldwide.

Installation Guidelines

Proper installation of the Bently Nevada 330708-00-24-10-11-05 requires adherence to specific torque and handling procedures. First, clean the 5/8-18 threaded mounting hole to remove debris or contaminants. Next, hand-thread the probe into position until it contacts the mounting surface. Then, apply the recommended torque of 15.2 N•m using a calibrated torque wrench, ensuring even seating without overstress. Simultaneously, route the FluidLoc cable while maintaining the 25.4 mm minimum bend radius to preserve cable integrity. For the ClickLoc connector, engage it firmly by hand until it clicks into place, then avoid exceeding the 0.565 N•m maximum torque. Finally, verify the Viton O-ring is properly seated for effective differential pressure sealing. If pressure testing is required for your specific application, coordinate with Bently Nevada's engineering team before installation.
